Windows ARM64 build gets stuck at installer.tasks

[pgovind]

I'm trying to build dotnet/runtime for windows on ARM64 with the following command line:

build clr+libs+libs.tests -a arm64 -c release

The build seems to be stuck at the installer.tasks step:

C:\Users\prgovi\Desktop\Work\runtime>build clr+libs+libs.tests -a arm64 -c release
  Determining projects to restore...
  Tool 'coverlet.console' (version '1.7.2') was restored. Available commands: coverlet

  Restore was successful.
  All projects are up-to-date for restore.

**The build just gets stuck at this point**

You might need a device to repro this. Let me know if you want to RDP into mine to test/repro or want logs.

Probably an MSBuild/SDK issue?

I'm reproducing the exact same issue in dotnet/runtime. The issue started after dotnet-installer merged this fix.

Possibly related: dotnet/msbuild#5474

Is it possible to get memory dumps during the hang? Or at least build with a diag-verbosity text log (binlogs are better except when they can't be flushed because of a hang/crash in the build) to get more clues about where things are going wrong?

@ladipro is chasing arm64 MSBuild problems, so I'll add this to his pile.

@carlossanlop has a minimal repro for this with diagnostics verbosity. Can you share the whole output in this issue?

Here's my output using build.cmd clr+libs -a arm64 -rc release -v diag

@eiriktsarpalis I think we can reduce the log and make it smaller if you do:

dotnet build tools-local\tasks\installer.tasks\ /p:TargetArchitecture=arm64 /v:diag
