This doesn't look right to me. Crossgen2 should build just fine. It may not run properly, but if we can't build it I think something else is going on.

#84781 disabled running crossgen2 for riscv. It should be done in the same place.

After some thinking I'm not so sure that this would be enough to just make changes in src/coreclr/crossgen-corelib.proj. Don't know what Risk-V guys did, but in my case I was able to build whole runtime + almost run all tests using standards method.

Will try to resurrect work. When I file issue, it was very ideal, since I have LA64 .NET 7 SDK and now it would require some jumping from the hoops on my side 😢

This seems obsolete with the crossgen-corelib change

This makes the build use packages that were just build instead of the one from the feed. Can we unify this with the mechanism that source build uses to achieve the same?

Why is this needed? Which live built packages do you need to restore and reference here?

That's allow me to use Microsoft.NETCore.App.Runtime.linux-loongarch64
as described in #78854

I use this as temporary stopgap to be able to use test scripts for build tests and run them (to some degree)

Source-build does not have a special mechanism to do this within a repo. The source-build mechanism is used to pickup packages that were built from a different repo within the source build.

Technically this line not needed, and only similar line in the file is here. But I assume concerns applied to line below.

@ViktorHofer isn't there some other way of forcing tests to use the live built packages?

@kant2002 I'm curious does the restore error only happen for the test_dependencies.fsproj you mentioned in #78854?

I do not actually know, since I do not fully understand how test infra setup. So I was worrying that I may break something further down the road. I can play according to your directions if you have some ideas to test
