Unable to switch SampleApps.sln build platform in Visual Studio

[jonthysell]

Problem Description

I'm trying to build SampleApps.sln, Debug x86, from main, in any VS supported version. By default when I open the solution, Debug ARM64 is chosen.

If I switch to x86, VS hangs forever:

This does not repro with 0.67-stable. I believe this may be some kind of race condition with VS trying to restore the nuget packages because of the new PackageReference stuff.

Steps To Reproduce

1. Clone, yarn install, yarn build repo
2. Open SampleApps.sln in VS 2019 or 2022
3. Change build platform to x86

Expected Results

Solution changes platform so I can build it

@JunielKatarn Jon thinks this might be due to the PackageReference change, could you take a look?

[JunielKatarn]

I'll take a look today. Verifying this should be simple.

I have successfully reproduced the issue on the latest main commit as of today (6dd9d8183c3dcf582684ae136a6fb771a213ed80).

Environment:

• npx 8.2.0
• Visual Studio 2019

However, this may not be inherent to the PackageReference feature.

• Commit 522f0c8f1eec1a4e52ea4105685b99a5f3ea96d9: No repro
  Last commit before introducing PacageReference for C++ projects.
• Commit bcdf9ad68eeda2967062f5137bc0f248e2ce7897: No repro either
  Commit introducing the PackageReference for C++ feature.

I'll do a binary search to find the first commit that hits the issue consistently.

Bug confirmed also in Visual Studio 2022.
