.NET 11 preview-7: Crossgen fails when building PowerShell on Linux and macOS

[daxian-dbw]

Description

We moved PowerShell to use the latest .NET SDK 11.0.100-preview.7 and that broke the PowerShell build on Linux and macOS. Build on Windows is fine.

Here are the CI runs
Linux -- Ubuntu 24.04: 27828/merge - 6179 · PowerShell/PowerShell@623e11d
macOS -- 15.7.7: 27828/merge - 6136 · PowerShell/PowerShell@623e11d

The build failure output:

Reproduction Steps

Building PowerShell on Linux (e.g. Ubuntu 24.04) and macOS (e.g. 15.7.7).
The _CreateR2RImages step will take forever and eventually timed out (cancelled by ctrl+c) with the error output shared above.

Expected behavior

PowerShell build successfully with the _CreateR2RImages step finishes within 30 seconds or so. That's the behavior before us moving to .NET 11 preview.7.

Actual behavior

_CreateR2RImages takes forever and eventually fails.

Regression?

Yes, a regression to .NET 11 preview.6 and prior versions of SDK.

Known Workarounds

None.

Configuration

Does your build recompile against .NET 11, or are you building against .NET 10 and running on .NET 11?

[agocke]

never mind -- I think this is an SDK failure, is that right?

[daxian-dbw]

The build is recompiling against .NET 11 and the _CreateR2RImages step takes forever on Unix platforms.

[daxian-dbw]

I created an issue in the dotnet/sdk repo dotnet/sdk#55762.
Feel free to close this one if that's where I should report the issue.

[agocke]

There are at least two separate issues here. The first is that the closure is missing the nrbf assembly, which is actually referenced. That looks like it might be a package authoring issue in winforms -- I have to dig deeper on that. The other is that failure takes 10 min. I almost have a PR ready for that. The last issue is that missing that DLL is a hard failure. We might be able to make it a warning instead.

The fix for the 10 minute failure is #132282
