[release/7.0.1xx] Build failure when source-build builds on itself due to _GenerateComposites

[ayakael]

Build of source-build fails to due to aspnetcore build failing when using prebuilt artifacts from non-portable build. This seems relevant to dotnet/installer#14549, as the failure does not occur when building using prebuilt portable bits:

A workaround is removing the _GenerateComposites target that triggers this error via:

This does not occur on dotnet6 as that target was added in dotnet7. As source-build does not care about composites, as far as I can tell, removal doesn't seem to be a problem.

[marcpopMSFT]

@dotnet/source-build-internal to take a look.

[MichaelSimons]

We saw this earlier and have added a patch which will be released with 7.0.1. The underlying issue is https://github.com/orgs/dotnet/projects/101/views/1.

What branch/sha are you seeing this?

[ayakael]

This failure was with 7.0.0. Closing as fixed on 7.0.1
