hmm:

src/sdk/src/Layout/redist/redist.csproj(0,0): error NU1100: (NETCORE_ENGINEERING_TELEMETRY=Restore) Unable to resolve 'Microsoft.NET.Sdk.Android.Manifest-10.0.100 (= 36.1.2)' for 'net11.0'. PackageSourceMapping is enabled, the following source(s) were not considered: /__w/1/s/.dotnet/library-packs, prebuilt, previously-source-built, reference-packages, source-built-aspnetcore, source-built-command-line-api, source-built-deployment-tools, source-built-diagnostics, source-built-fsharp, source-built-msbuild, source-built-nuget-client, source-built-razor, source-built-roslyn, source-built-runtime, source-built-source-build-reference-packages, source-built-sourcelink, source-built-symreader, source-built-templating, source-built-transport-arcade, source-built-transport-aspnetcore, source-built-transport-cecil, source-built-transport-msbuild, source-built-transport-razor, source-built-transport-runtime, source-built-transport-sourcelink, source-built-transport-windowsdesktop, source-built-transport-winforms, source-built-transport-wpf, source-built-vstest, source-built-windowsdesktop, source-built-xdt.

The error is looking for a package on dotnet-public:

• https://dev.azure.com/dnceng/public/_artifacts/feed/dotnet-public/NuGet/Microsoft.NET.Sdk.Android.Manifest-10.0.100/overview/36.1.2

Let me review the package source mappings.

@jonathanpeppers this is the source-build job so it can't use dotnet-public. if it's expected that the package is still referenced in 11.0 then you need to keep it in source-build-reference-packages

Ok, I see. I can undo the "deletion" I did:

• dotnet/source-build-reference-packages@4c647b3

This PR should now just be the addition of the .NET 11 manifests now.

I thought the whole point of adding the updated versions was so that they could be referenced. But they aren't being referenced which is why the build failure occurred still looking for the old version. See https://github.com/dotnet/dotnet/blob/release/11.0.1xx-preview1/src/sdk/eng/Versions.props#L151-L163
