@mthalman @dsplaisted The following code in the NuGet.config file was removed by dotnet/dotnet, which caused the error. Should we contact the dotnet team to fix it, or should we add it back ourselves?

 <add key="darc-pub-dotnet-dotnet-fad253f" value="https://pkgs.dev.azure.com/dnceng/public/_packaging/darc-pub-dotnet-dotnet-fad253f5/nuget/v3/index.json" />

 <add key="darc-int-dotnet-dotnet-fad253f" value="true" />

Error:
test/Microsoft.NET.Sdk.WorkloadManifestReader.Tests/Microsoft.NET.Sdk.WorkloadManifestReader.Tests.csproj(0,0): error NU1603: (NETCORE_ENGINEERING_TELEMETRY=Restore) Warning As Error: Microsoft.NET.Sdk.WorkloadManifestReader.Tests depends on Microsoft.Deployment.DotNet.Releases (>= 2.0.0-preview.1.25569.105) but Microsoft.Deployment.DotNet.Releases 2.0.0-preview.1.25569.105 was not found. Microsoft.Deployment.DotNet.Releases 2.0.0-preview.1.25569.110 was resolved instead.

@mmitche @marcpopMSFT I've reverted the NuGet.config changes in 8589691, and that made the build succeed at least locally. How is this flow supposed to work with the feeds?

[mmitche]

That feed removal looks correct. The feeds were there for shipping packages that would have shipped in 10.0.1, and so they shouldn't be needed any longer.

[mmitche]

There might be multiple issues here:

• There's an implicit dependency on Microsoft.Deployment.DotNet.Releases, but the repo doesn't call out the dependency specifically in the Version.Details.xml, and so Maestro does not know to keep the feed around. It happened to work before because some other unreleased shipped dependency was called out explicitly in the V.D.xml. So adding that dependency would do the trick.
• At the same time, it's weird that this package is shipping and non-stable, but got pushed to the isolated feed. This is not necessary for this package. Newer build have this fixed. I think that this was a point in time issue for 10.0.1.

So, I think you can ignore the problem and keep adding the feed back as necessary. We'll switch to active code flow soon and I think the problem will go away.

Current test failures look like this:

Microsoft.NET.Build.Tasks.BuildErrorException : NETSDK1005: Assets file '/tmp/helix/working/B0D809CC/t/tmpvdOWKg.tmp' doesn't have a target for 'net6.0'. Ensure that restore has run and that you have included 'net6.0' in the TargetFrameworks for your project.

It looks like this may be caused by NuGet/NuGet.Client#6992.

Thank you. I think I agree. The others should be fixed with a /completions run. @nkolev92 @jeffkl may you PTAL at what we think is a result of NuGet/NuGet.Client#6992?

[nkolev92]

I'll look into this.
@dsplaisted e-mailed about it.
