@marcpopMSFT @JL03-Yue This issue repro on the latest build for both .NET 9 Preview1 and .NET 8 Servicing, could you please help confirm whether it is a blocker for .NET 9 Preview1 and .NET 8 Servicing?

@marcpopMSFT @JL03-Yue According the last update, it seems this issue has been moved to .NET 9.0 servicing 9.0.1xx. Could you please help confirm what's the plan for the .NET 8.x issue #38354 ?

[marcpopMSFT]

We'll discuss in triage. Annie has left the team so we do not currently have someone digging into the tools issues anymore. We're short on time for 8.0.4xx and would not fix it in any other 8 sdk.

Verified this issue and it has been Fixed on dotnet-sdk-9.0.100-preview.7.24352.8. Hence closing this issue.
