Missing NuGet package

[aelij]

Describe the issue or request
When using the latest release (3.0.0-beta.20211013.1), the corresponding NuGet package cannot be found:

  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.AutoRest.CSharp" Version="3.0.0-beta.20211013.1" PrivateAssets="All" />
  </ItemGroup>

error NU1102: Unable to find package Microsoft.Azure.AutoRest.CSharp with version (>= 3.0.0-beta.20211013.1)
error NU1102:   - Found 144 version(s) in https://azuresdkartifacts.blob.core.windows.net/azure-sdk-tools/index.json [ Nearest version: 3.0.0-beta.20210604.3 ]

@weshaggard @pakrym do we have any objections on publishing Microsoft.Azure.AutoRest.CSharp into nuget.org?

[aelij]

@AlexanderSher The problem here is that even the custom feed doesn't contain this version (that was emitted by autorest). But I would be very happy to also see it on nuget.org :)

[weshaggard]

We have been trying to avoid publishing to nuget.org given this is only for carrying our autorest extension.

@aelij I see that version on the feed. https://dev.azure.com/azure-sdk/public/_packaging?_a=package&feed=azure-sdk-for-net&package=Microsoft.Azure.AutoRest.CSharp&protocolType=NuGet&version=3.0.0-beta.20211013.1&view=overview.

@weshaggard autorest.csharp adds a different feed to the generated .csproj - https://azuresdkartifacts.blob.core.windows.net/azure-sdk-tools/index.json

[weshaggard]

@aelij that was the old feed we used to publish to but we now publish to the https://pkgs.dev.azure.com/azure-sdk/public/_packaging/azure-sdk-for-net/nuget/v3/index.json. When you autorest.csharp adds a different feed what do you mean my that? Is there some tool/script that is automatically adding that as a feed? If so we should update that to the new feed.

[aelij]

autorest.csharp generates a .csproj with:

<PropertyGroup>
  <RestoreAdditionalProjectSources>https://azuresdkartifacts.blob.core.windows.net/azure-sdk-tools/index.json</RestoreAdditionalProjectSources>
</PropertyGroup>

[weshaggard]

I see. @AlexanderSher @ShivangiReja looks like we need to update this feed at https://github.com/Azure/autorest.csharp/blob/feature/v3/src/AutoRest.CSharp/Common/AutoRest/Plugins/CSharpProj.cs#L49.

currently running into the same issue as well

What is the plan with this package?

The npm package @autorest/csharp for v3 is a beta package.

The NuGet package Microsoft.Azure.AutoRest.CSharp is a prerelease package and isn't on the official NuGet feed, but is instead on an Azure specific feed.

I've tried to search for docs/roadmap on GA for use outside of Azure SDK repository, but I can't find any information.

It would be nice to see some information as to when we can expect stable versions of each package as well as an official NuGet package, otherwise, we cannot migrate off of V2.

Any update on this? I still get the same error, and the feed URL in the csproj is still the old one as @weshaggard said. Once I replace the URL with https://pkgs.dev.azure.com/azure-sdk/public/_packaging/azure-sdk-for-net/nuget/v3/index.json it works but I also have to change <LangVersion>8.0</LangVersion> to 9.0 to compile successfully.

Not only is the generate csproj pointing to the wrong feed, it also apparently requies C# 9.0 or greater, or is some AZURE_NULLABLE constant supposed to be set to false?

Bumping for visibility..

I see. @AlexanderSher @ShivangiReja looks like we need to update this feed at https://github.com/Azure/autorest.csharp/blob/feature/v3/src/AutoRest.CSharp/Common/AutoRest/Plugins/CSharpProj.cs#L49.

@weshaggard Others noted this already, but the LangVersion also needs to be bumped to 9.0 or latest for the build to work.

Here is a workaround I am using during my build process. Save a Invoke-FixCSProj.ps1 file with the following contents

param(
	[Parameter(Mandatory = $true)]
	[string]
	$CSProj,
	[Parameter(Mandatory = $false)]
	[string]
	$LangVersion = "9.0"
)

$xml = [XML](Get-Content $CSProj)

$xml.Project.PropertyGroup[1].LangVersion = $LangVersion
$xml.Project.PropertyGroup[1].RestoreAdditionalProjectSources = "https://pkgs.dev.azure.com/azure-sdk/public/_packaging/azure-sdk-for-net/nuget/v3/index.json"

$xml.OuterXml | Out-File $CSProj

Then you can run it like

./Invoke-FixCSProj.ps1 -CSProj <pathToCSProj>

And this will "fix" the csproj file in-place and set the LangVersion to 9.0 (this is overridable in case you want latest). This doesn't format the CSProj like it was before but it works fine.
