Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/checkout@v4, actions/setup-dotnet@v4. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

Nullability of reference types in type of parameter 'obj' of 'lambda expression' doesn't match the target delegate 'SyncWorkerEntry.SyncWorkerDelegate' (possibly because of nullability attributes).

Possible null reference assignment.

Dereference of a possibly null reference.

Possible null reference assignment.

Converting null literal or possible null value to non-nullable type.

Possible null reference assignment.

Converting null literal or possible null value to non-nullable type.

The switch expression does not handle some values of its input type (it is not exhaustive) involving an unnamed enum value. For example, the pattern '(Multiplayer.Common.DevModeScope)2' is not covered.

Possible null reference return.

ProjectReference '/home/runner/work/Multiplayer/Multiplayer/Source/Common/Common.csproj' was resolved using '.NETFramework,Version=v4.8' instead of the project target framework '.NETCoreApp,Version=v8.0'. This project may not be fully compatible with your project.

Non-nullable field 'name' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.
