Session Handoff — 2026-02-23 (Session 3)

Context / User Directive (New, strict)

  • The user clarified the architecture rule during audit:
    • ViewModels should NOT have app logic. They should delegate all app logic to CQRS handlers.
    • Code-behind should remain UI-only, except explicitly documented exceptions.
  • Additional directive (must guide all future work):
    • Design and implement for CORRECTNESS, COMPLETENESS, and ADHERENCE.
    • Do not mask broken standards with compliant wrappers.
    • Prefer correct refactors over surface-level compliance.

Compliance Audit (CQRS + Code-Behind) — Detailed Findings

Audit Scope

  • Included src/McpServerManager.Core/ (shared ViewModels, Commands, CQRS)
  • Included src/McpServerManager.Desktop/ and src/McpServerManager.Android/ code-behind (*.axaml.cs)
  • Included legacy src/McpServerManager/ because the request said "all code"
  • Reference points used:
    • HANDOFF.md architecture notes (CQRS/MVVM/3-project architecture)
    • docs/EXCEPTION-EVALUATION.md documented Markdown.Avalonia code-behind exception

Architectural Rule Interpretation Used for Audit

  • Compliant ViewModel behavior:
    • UI state + projection + dispatching commands/queries to mediator
    • Minimal UI-only transformations are acceptable (e.g., local formatting of already-loaded state)
  • Non-compliant ViewModel behavior:
    • Network calls, filesystem IO, process launching, file watchers, JSON parsing/aggregation, service construction/composition
  • Compliant CQRS handler behavior:
    • Operates on command/query DTOs and dependencies (services), not on concrete ViewModel internals
  • Non-compliant CQRS handler behavior:
    • Accepts ViewModel instance in command payload and calls ViewModel.*Internal(...)
  • Compliant code-behind behavior:
    • UI event wiring, control sync, view-only layout persistence
  • Allowed exception:
    • Markdown viewer code-behind binding workaround due Markdown.Avalonia compatibility issue (documented)

Quantitative Signals (used to establish systemic vs isolated issues)

  • 24 *.axaml.cs files under src/
  • 32 command-handler calls in Core/Commands that invoke ViewModel.*Internal(...)
  • 36 *Internal(...) methods declared in Core/ViewModels
  • 6 code-behind hits for chat-window composition/config operations (OllamaLogAgentService, AgentConfigIo, new ChatWindowViewModel(...)) across current + legacy desktop shells

CQRS Compliance Result (Current State)

  • Result: FAIL (systemic)
  • The repo contains a real CQRS foundation (Mediator, handler interfaces, service-based handlers in some modules), but a large portion of the command layer acts as a wrapper over ViewModel internals rather than owning the application behavior.

Code-Behind Compliance Result (Current State)

  • Result: PARTIAL
  • Most code-behind in Desktop/Android is UI-oriented and likely compliant.
  • Desktop shell (MainWindow.axaml.cs) and legacy shell still contain application composition / config IO / viewmodel creation logic.
  • Markdown viewer workaround in legacy code-behind is explicitly documented and treated as allowed.

Detailed Audit Evidence (Representative, not exhaustive)

1) CQRS wrapper anti-pattern in Core/Commands (systemic)

Many commands carry a concrete ViewModel instance and handlers call ViewModel.*Internal(...), which means the app logic remains in the ViewModel and the handler is only a pass-through.

Examples:

  • src/McpServerManager.Core/Commands/AllCommands.cs
    • NavigateBackCommand stores MainWindowViewModel
    • NavigateBackHandler calls command.ViewModel.NavigateBackInternal()
    • Same pattern repeated for selection/navigation/archive/open actions
  • src/McpServerManager.Core/Commands/ChatCommands.cs
    • ChatSendMessageCommand stores ChatWindowViewModel
    • ChatSendMessageHandler calls command.ViewModel.SendAsyncInternal()
    • Similar for models/prompts/config commands
  • src/McpServerManager.Core/Commands/AsyncCommands.cs
    • Commands store MainWindowViewModel
    • Handlers read vm._mediator, vm.McpSessionService, and invoke multiple *Internal(...) methods

Why this fails the rule:

  • CQRS handlers are not the application logic owners.
  • ViewModel internals become a required handler API (*Internal) and effectively form an application service surface.
  • The command layer depends directly on UI state containers, reversing the intended dependency direction.

2) MainWindowViewModel contains substantial app logic (Core)

MainWindowViewModel currently owns responsibilities that should live in handlers/services:

  • Service composition / endpoint switching
    • Creates McpWorkspaceService, McpTodoService, McpSessionLogService
    • Rebinds handlers on endpoint change
  • Workspace health checks
    • Direct network service creation and GetHealthAsync() calls
  • Workspace catalog loading
    • Direct _workspaceCatalogService.QueryAsync()
  • AGENTS file watcher
    • FileSystemWatcher lifecycle, debounce scheduling, reload versioning
  • AGENTS file IO
    • File existence checks, timestamp reads, file content loading, status updates
  • Session loading/parsing
    • Direct session service fetches
    • tree building and JSON processing orchestration
  • Local file/archive operations
    • File.Move, File.ReadAllText, parsing, open-in-browser/process start behaviors

This violates the clarified rule because the ViewModel remains the application coordinator and executor, not a thin state adapter.

3) AsyncCommands handlers still depend on VM internals (worse than simple wrappers)

AsyncCommands are more tightly coupled than AllCommands/ChatCommands:

  • They access vm._mediator.TrackBackgroundWork(...)
  • They call vm.McpSessionService.GetAllSessionsAsync(...)
  • They call vm.BuildUnifiedSummaryAndIndexInternal(...), vm.BuildJsonTreeInternal(...), vm.UpdateFilteredSearchEntriesInternal()
  • They mix app flow control, domain transformations, and UI update dispatch through the ViewModel

This means:

  • The handler layer is not independent
  • The ViewModel and handlers are mutually entangled
  • Unit-level testing of handlers without ViewModel internals is difficult/impossible

4) ChatWindowViewModel retains app logic (Core)

ChatWindowViewModel still performs:

  • File/process launching for config/prompt files
  • Prompt template file IO
  • Ollama model discovery (OllamaLogAgentService.GetAvailableModelsAsync)
  • Send pipeline orchestration including background agent call and reply/error handling

Even when invoked through the mediator, this remains non-compliant because handlers currently delegate back to the ViewModel (ChatCommands wrapper pattern).

5) TodoListViewModel and WorkspaceViewModel act as composition roots for their command handlers

These viewmodels currently create services and register mediator handlers themselves:

  • TodoListViewModel.RegisterCqrsHandlers(McpTodoService service) and SetMcpBaseUrl(...)
  • WorkspaceViewModel.RegisterCqrsHandlers(McpWorkspaceService service) and SetMcpBaseUrl(...)

This is better than the MainWindowViewModel wrapper pattern in some respects (handlers are service-based), but still not ideal under the strict rule because:

  • ViewModels perform application service composition and lifecycle management
  • Handler registration/service replacement is tied to UI state objects

6) Desktop MainWindow code-behind contains application composition logic

src/McpServerManager.Desktop/Views/MainWindow.axaml.cs currently:

  • instantiates OllamaLogAgentService
  • reads config via AgentConfigIo.GetModelFromConfig()
  • constructs ChatWindowViewModel(...)
  • writes persisted chat-window state via LayoutSettingsIo in chat close path

This is beyond UI-only code-behind. The window should host UI and delegate composition/orchestration to a higher-level application layer (or request it from a ViewModel/CQRS flow).

7) Legacy project (src/McpServerManager) remains broadly non-compliant (expected, but real)

The legacy standalone project predates the refactor and still contains:

  • ViewModel app logic and direct service calls
  • code-behind chat composition logic
  • direct file/process/network orchestration in viewmodels

This matters because the user requested an audit of "all code". If legacy code remains in active scope, overall compliance is not met.

Blame Attribution for Non-Compliant Code (line-level snapshot)

Methodology / caveats

  • Blame was captured against the current working tree (git blame --line-porcelain on the exact line refs cited in the audit).
  • This repo is currently dirty, so some lines correctly blame to:
    • 0000000000000000000000000000000000000000 / Not Committed Yet
  • Blame identifies the most recent commit touching the specific line, not necessarily the original architectural decision.

Agent / model provenance determination for blamed commits

Method used

  • Inspected each blamed commit with:
    • git show -s --show-notes --format=... <commit>
  • Looked for explicit provenance markers in commit body/trailers (e.g., Co-authored-by, Generated with, Model:).
  • Also spot-checked history for AI-related trailers/markers.

Result summary

  • Author/committer on all blamed commits: sharpninja <ninja@thesharp.ninja>
  • Explicit agent provenance found on some commits: Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  • Explicit model provenance (e.g., GPT-4o / Claude / etc.): not recorded in any blamed commit metadata/body
  • Uncommitted working-tree lines (000...): no commit metadata exists, so agent/model cannot be determined from Git; working tree may contain mixed authorship

Provenance implications for the audit

  • The audit can reliably distinguish:
    • commits with explicit Copilot co-author provenance
    • commits with no explicit AI provenance recorded
  • The audit cannot reliably determine the exact model used for any blamed commit from Git metadata alone.
  • Absence of an AI trailer is not evidence of human-only authorship; it only means no explicit provenance was recorded in the commit metadata/body.

Attribution implications (for refactor planning)

  • Several non-compliant patterns were introduced in commits labeled as CQRS refactors (0854c8a..., d0b0a6b...), which confirms the audit conclusion: CQRS was introduced structurally, but logic ownership was not fully migrated out of ViewModels.
  • Some lines are last-touched by mechanical or incidental commits (74e099e... ConfigureAwait refactor, 2987350... busy-state fix), so blame should not be read as sole architectural ownership, only as last-touch lineage.
  • The AGENTS watcher / workspace-health non-compliance is currently in uncommitted working-tree changes (Not Committed Yet) and should be corrected before commit by moving watcher/file-load/health logic into handlers/services rather than preserving it in MainWindowViewModel.

Explicitly Allowed / Not Flagged as Violations

  • Markdown viewer code-behind assignment fallback in legacy shell:
    • Documented in docs/EXCEPTION-EVALUATION.md
    • Used to work around Markdown.Avalonia binding incompatibility
  • Layout splitter/window persistence in code-behind:
    • Treated as UI concerns (especially after splitter persistence helper refactor)
  • Control synchronization for AvaloniaEdit text bindings:
    • Treated as UI interop, not application logic

Root Cause Summary (Why the drift happened)

  • The project introduced CQRS incrementally without completing responsibility migration.
  • Commands/handlers were often added as dispatch wrappers to keep [RelayCommand] call sites stable.
  • ViewModels accumulated "internal" methods as the real application API.
  • This created the appearance of CQRS while preserving the original ViewModel-centric application logic.

Refactor Direction (Required for actual compliance)

To satisfy the clarified rule, the project must move from "CQRS wrappers" to "CQRS-owned application logic":

  1. Stop passing concrete ViewModels into commands
  • Commands should carry IDs, DTOs, user inputs, and selection tokens only.
  • Handlers should depend on services and return result DTOs.
  1. Remove *Internal(...) as application API surface
  • Keep ViewModel methods focused on:
    • command/query dispatch
    • applying returned results to observable state
    • simple UI-only transforms
  1. Move app logic to handlers + services
  • Filesystem IO, process start, network calls, parsing, tree building, watchers, orchestration
  1. Move code-behind composition into an application/service layer
  • Shell code-behind should not instantiate business services or ViewModels with config IO dependencies.
  1. Treat legacy code explicitly
  • Either:
    • keep legacy project out of compliance scope and mark deprecated
    • or schedule migration/refactor work there too

Implementation Kickoff Plan (This Session)

Begin by refactoring the Chat subsystem as a pilot because it is self-contained and demonstrates the anti-pattern clearly:

  • Replace Chat CQRS wrapper handlers with real handlers that do not depend on ChatWindowViewModel
  • Move chat app logic (model discovery, prompt file loading/opening, agent send call) into service-backed handlers
  • Keep ViewModel as UI state + command/query dispatch + state application
  • Leave UI-only behaviors (e.g., assigning selected prompt text to input, message list projection) in ViewModel where appropriate

This provides a concrete, correct pattern to apply next to MainWindowViewModel, AsyncCommands, and workspace/todo composition.

Changes Made This Session (Session 3)

  • Performed a repo-wide CQRS/code-behind compliance audit against the clarified rule.
  • Captured systemic failure modes and measurable indicators.
  • Recorded the strict implementation directive and refactor standard in this handoff.
  • Next action (in-progress): start refactoring Chat CQRS handlers to remove ViewModel wrapper usage.

Session Handoff — 2026-02-20 (Session 2)

Project Overview

McpServerManager is an Avalonia UI application (.NET 9) for viewing and analyzing AI agent session logs. It connects to an MCP server (FunWasHad project at localhost:7147) to fetch session data and TODO items, displaying them in a JSON tree, search index grid, structured details view, and a full TODO management tab with an integrated YAML editor. Includes an integrated AI chat window (Ollama-backed, Desktop only). Runs on Desktop (Windows/Linux) and Android (tablet + phone).

Repository Structure

  • src/McpServerManager.Core/ — Shared library (net9.0): ViewModels, Models, Services, Commands, CQRS
  • src/McpServerManager.Desktop/ — Desktop app (net9.0 WinExe, Avalonia)
  • src/McpServerManager.Android/ — Android app (net9.0-android, Avalonia)
  • src/McpServerManager/ — Legacy standalone desktop app (pre-refactor, still builds)
  • lib/Markdown.Avalonia/ — Git submodule for markdown rendering
  • docs/ — Documentation: toc.yml, todo.md, EXCEPTION-EVALUATION.md, fdroid/
  • todo.yaml — Project backlog in YAML format

Key Architecture

  • MVVM pattern with [ObservableProperty] and [RelayCommand] source generators (CommunityToolkit.Mvvm 8.2.1)
  • CQRS via project's own Mediator class with ICommand<T>/IQuery<T> + handlers
  • 3-project architecture: Core (shared lib) → Desktop + Android. Views in platform projects, ViewModels in Core.
  • TabControl shell: Desktop MainWindow and Android TabletMainView use TabControl with 3 tabs: "Request Tracker", "Todos", "Logs"
  • Status bar: Lives in MainWindow.axaml (Desktop) and TabletMainView.axaml (Android) — below the TabControl, not inside individual views
  • MCP server scope: The MCP at localhost:7147 belongs to FunWasHad, not this project. McpServerManager is a read/write client.
  • Config: appsettings.config (JSON) for Mcp.BaseUrl, Paths.SessionsRootPath, Paths.HtmlCacheDirectory. Android has no appsettings.config — uses ConnectionDialogView to get MCP URL at startup (default 10.0.2.2:7147).
  • Layout persistence: LayoutSettingsIo saves/restores window size, position, splitter heights, chat window state
  • Logging: AppLogService singleton implements ILoggerFactory/ILoggerProvider. All logging uses ILogger via AppLogService.Instance.CreateLogger("Category"). Logs feed LogViewModel for the Logs tab.
  • ConfigureAwait(true): Used everywhere (not false). This is a UI app — always continue on captured context.
  • SelectableTextBlock: All TextBlock controls have been replaced with SelectableTextBlock across all 3 platforms.

Major Features Added

ILogger Infrastructure (Core/Services/AppLogService.cs)

  • AppLogService singleton implements ILoggerFactory and ILoggerProvider
  • AppLogger (per-category) and AppLogger<T> (generic) classes
  • LogEntry model with Display property formatting [HH:mm:ss.fff] [Level] [Source] Message
  • NewLogEntry event fires for each log entry → consumed by LogViewModel
  • Added Microsoft.Extensions.Logging.Abstractions v9.0.3 to Core .csproj

Logs Tab (Core/ViewModels/LogViewModel.cs, Desktop+Android Views/LogView.axaml)

  • Full log viewer with level filter dropdown (default: Information)
  • Pause/Resume toggle — paused entries buffer in _pauseBuffer, flushed on resume
  • Auto-select newest entry, auto-scroll to bottom
  • Context menu: Copy, Copy All, Clear (auto-pauses while context menu open)
  • Monospace font (Cascadia Code, 14px), line-by-line display
  • Created on both Desktop and Android platforms

Status Bar Moved to Main View

  • Desktop: MainWindow.axaml wraps TabControl in Grid RowDefinitions="*,Auto", status bar in row 1
  • Android: TabletMainView.axaml same pattern with AnimatedStatusBar
  • Removed from McpServerManagerView.axaml and McpServerManagerTabletView.axaml
  • Updated SaveCurrentLayoutToSettings row count checks (portrait ≥5, landscape ≥3)

Todo Global Status Events

  • TodoListViewModel.GlobalStatusChanged event fires on load/open/save with descriptive messages
  • MainWindowViewModel subscribes in CreateTodoViewModel() factory, forwards to StatusMessage

Copilot CLI Commands (Core/ViewModels/TodoListViewModel.cs)

  • 3 new [RelayCommand] methods: CopilotStatusAsync, CopilotPlanAsync, CopilotImplementAsync
  • RunCopilotCommandAsync helper streams output line-by-line into editor via CopilotCliService
  • IsCopilotRunning observable property for UI state
  • Context menu items added to Desktop TodoListView.axaml

SelectableTextBlock Replacement

  • All TextBlock controls replaced with SelectableTextBlock across 16 .axaml files on all 3 platforms

Android Fixes

  • TODO loading: TodoViewModel was using AppSettings.ResolveMcpBaseUrl() which throws on Android (no appsettings.config). Fixed to use _mcpBaseUrl stored from constructor parameter.
  • McpTodoService timeout: Reduced from 30s to 5s to prevent ANR on connection failure
  • Ollama guard: TryStartOllamaIfNeeded() in AsyncCommands.cs now checks OS platform (Windows/Linux/macOS only)
  • TODO auto-load timing: Added OnDataContextChanged fallback in Android TodoListView.axaml.cs for when Loaded fires before DataContext is set
  • Editor always visible: Removed IsEditorVisible toggling — editor panel and toolbar always shown

Log Level Audit (multiple passes)

  • IsBusy state changes → Debug
  • Window layout, persisting/reading data, AI messages → Information
  • Navigation failures → Warning
  • Non-fatal settings issues → Warning (demoted from Error)
  • Default log viewer filter → Information

Other Changes

  • All ConfigureAwait(false) → ConfigureAwait(true) across 12 files (53 occurrences)
  • Graceful Pandoc handling: IsPandocAvailable() static check with caching
  • Removed manual InitializeComponent() from TodoListView, LogView, and McpServerManagerView (was shadowing Avalonia's source-generated version)
  • Todo list item template: ID prominent (SemiBold, larger), no checkboxes or priority display
  • Log font size increased from 12 to 14 on both Desktop and Android

Build Notes

  • Desktop: dotnet build src\McpServerManager.Desktop\McpServerManager.Desktop.csproj
  • Android (emulator x64): dotnet build src\McpServerManager.Android\McpServerManager.Android.csproj -t:Install -f net9.0-android -c Debug -p:AdbTarget="-s emulator-5554" -p:RuntimeIdentifier=android-x64
  • Android launch: adb -s emulator-5554 shell am force-stop ninja.thesharp.mcpservermanager && adb -s emulator-5554 shell am start -n ninja.thesharp.mcpservermanager/crc64f9c6b05aaee59f0e.MainActivity
  • CRITICAL: The Android emulator (emulator-5554) is x86_64. Must use -p:RuntimeIdentifier=android-x64 or Fast Deployment puts assemblies in arm64-v8a which the emulator can't find → instant crash.
  • Running instance locks DLLs — kill the McpServerManager process before rebuilding (Stop-Process -Id <PID>)
  • Avalonia 11.3.12, FluentAvaloniaUI 2.4.1 (2.5.0 needs .NET 10), AvaloniaEdit 11.0.0, CommunityToolkit.Mvvm 8.2.1
  • Markdown.Avalonia submodule needs Linux CI patching (.props only defines PackageTargetFrameworks for Windows_NT)

Current State

  • Desktop and Android builds succeed with 0 errors
  • All 6 commits from this session are on main branch (not pushed to origin)
  • Android app deployed and running on emulator-5554
  • PhoneMainView NOT modified (no tabs on phone)
  • AI chat button wired on Desktop only (Android does not have ChatWindow)
  • Submodule lib/Markdown.Avalonia shows as modified (dirty) — not a real change

Known Issues / Next Steps

  • ANR on Android startup: Initial MCP session loading (213 requests / 37 sessions) saturates the UI thread during tree building. The HTTP fetching is async/background, but Dispatcher.UIThread.InvokeAsync for the tree node population blocks. Consider batching tree updates or deferring until the tab is visible.
  • View unification (RT-001): Desktop and Android views are separate — could share more XAML
  • Copilot CLI context menu only on Desktop — not wired on Android
  • Android editor: Always visible but OnGroupListBoxSelectionChanged calls OpenSelectedTodoCommand which fetches from MCP. Verify this works reliably on slower connections.
  • Push to origin: 6 commits on main not yet pushed

Connected Devices

  • emulator-5554 — Android tablet emulator (x86_64, 1600x2560)
  • ZD222QH58Q — Physical Android device (not used this session)

MVP-APP-006 Phase 0 Compliance Tranche (Audit + Guardrails)

Status: completed baseline governance/inventory phase (refactor not started in this tranche)

Artifacts added

  • Compliance spec + freeze rule:
    • docs/architecture/compliance/COMPLIANCE-SPEC.md
  • Compliance matrix (violation families, target design, replacement owner):
    • docs/architecture/compliance/COMPLIANCE-MATRIX.md
  • Core ViewModel app-logic inventory:
    • docs/architecture/compliance/INVENTORY-CORE-VIEWMODEL-APP-LOGIC.md
  • Core handler/ViewModel coupling inventory:
    • docs/architecture/compliance/INVENTORY-CORE-HANDLER-VM-COUPLING.md
  • Desktop/Android code-behind classification inventory:
    • docs/architecture/compliance/INVENTORY-CODE-BEHIND.md
  • Legacy project scope decision + inventory:
    • docs/architecture/compliance/LEGACY-COMPLIANCE-SCOPE.md
  • PR compliance checklist:
    • .github/pull_request_template.md
  • CI guardrail scripts:
    • tools/compliance/Check-CqrsBoundaries.ps1
    • tools/compliance/Check-ViewModelBoundaries.ps1
    • tools/compliance/Invoke-ArchitectureChecks.ps1

CI enforcement change

  • Added Phase 0 architecture guardrail step to:
    • .github/workflows/build-android.yml
  • The guardrails intentionally fail while known violations remain. This is expected and aligns with the no-wrapper/no-masking directive.

Scope decision (legacy)

  • Active compliance scope for MVP-APP-006 is Core, Desktop, and Android.
  • src/McpServerManager remains visible in audit documentation but is excluded from Phase 0 guardrail execution pending explicit deprecation/refactor work.

Relationship to existing audit/blame sections

  • The detailed findings and blame attribution earlier in this file remain the line-level source of truth for current non-compliance.
  • The new docs above convert those findings into a tracked matrix and executable guardrails.

MVP-APP-006 Chat Refactor Tranche (Post-Phase 0)

Status: Chat compliance tranche completed for tasks 9, 12, 13, 14, 15, 16, 17, 18, and 33 (MainWindow/Todo/Workspace epic work remains)

Completed in this tranche

  • Added chat application service interfaces and default implementations for:
    • prompt template loading
    • chat-related local file open/config file operations
    • model discovery
    • send orchestration contract (wrapper introduced for later migration)
  • Replaced Core/Commands/ChatCommands.cs wrapper handlers with DTO/result-based handlers:
    • no ChatWindowViewModel command payload properties remain
    • no handlers call ViewModel.*Internal(...)
  • Converted chat model discovery to a CQRS query handler/service path
  • Refactored Core/ViewModels/ChatWindowViewModel.cs so these flows dispatch/apply results instead of owning file-open/prompt-load/model-discovery logic
  • Moved chat send backend orchestration to CQRS command handler + app service (ChatSendMessageHandler)
  • Added compliant ChatWindowViewModelFactory to own chat mediator/handler registration and config IO integration
  • Refactored Desktop MainWindow code-behind to use the chat factory (removed direct chat service/config/VM construction)

Remaining Chat-specific non-compliance in active scope

  • None identified in the active Chat subsystem path after this tranche.
  • CancelSend() remains in ChatWindowViewModel as UI cancellation-token ownership (allowed by current compliance spec).
  • Legacy chat window path in src/McpServerManager remains out of active scope (see legacy scope decision doc).

Files changed in this tranche

  • src/McpServerManager.Core/Services/ChatApplicationServices.cs
  • src/McpServerManager.Core/Services/ChatWindowViewModelFactory.cs
  • src/McpServerManager.Core/Commands/ChatCommands.cs
  • src/McpServerManager.Core/ViewModels/ChatWindowViewModel.cs
  • src/McpServerManager.Desktop/Views/MainWindow.axaml.cs

Validation

  • dotnet build src/McpServerManager.Core/McpServerManager.Core.csproj -c Debug --no-restore ⚠️ one run failed due transient file lock (CS2012, Defender lock on obj DLL); subsequent Desktop build succeeded and compiled Core
  • dotnet build src/McpServerManager.Desktop/McpServerManager.Desktop.csproj -c Debug --no-restore ✅
