@mkArtakMSFT This issue is found during .NET 8 RC1 validation. Could you please confirm whether it is a blocker for RC1? Thanks.

[mkArtakMSFT]

@javiercn can you please give this scenario a try and see if this is an issue with our framework, or with the dependency?

[Junjun-zhao]

@javiercn Do you have any update for this issue? Thanks for helping investigate it.

[Junjun-zhao]

@javiercn @mkArtakMSFT Thank you for checking this issue. Now we are RC2 validation, this issue still repro. Do you have a try for this scenario? If so, is it an issue for our Framework? If no, do you have any plans for it?

@Junjun-zhao what is the behavior on .NET7? The repro information indicates this was passing in .NET6 and failed in .NET8 RC1. Verify Scenarios: 1). Windows 10 21H2 AMD64 + dotnet-sdk-8.0.100-rc.1.23415.7: Fail 2). Windows 10 21H2 AMD64 + dotnet-sdk-6.0.413-win-x64: Pass 3). Windows 10 21H2 AMD64 + dotnet-sdk-8.0.100-rc.1.23412.1: Pass Can you check and clarify the behavior with .NET 7 or other .NET 8 Previews? That will help narrow down the release where this change was introduced.

[mkArtakMSFT]

Can you check and clarify the behavior with .NET 7 or other .NET 8 Previews?

No need for verifying other .NET 8 Previews. Just the latest 7.0 and 8.0-rc2 please.

[Junjun-zhao]

No need for verifying other .NET 8 Previews. Just the latest 7.0 and 8.0-rc2 please.

It works on the latest 7.0, the latest 8.0-rc2 is not working. And it fails starting with 8.0.100-rc.1.23415.7. I have updated the verification scenario as shown below, please let me know if anything is unclear.

Verify Scenarios: 1). Windows 10 21H2 AMD64 + dotnet-sdk-6.0.413-win-x64: Pass 2). Windows 10 21H2 AMD64 + dotnet-sdk-7.0.402-win-x64: Pass 3). Windows 10 21H2 AMD64 + dotnet-sdk-8.0.100-rc.1.23412.1: Pass 4). Windows 10 21H2 AMD64 + dotnet-sdk-8.0.100-rc.1.23415.7: Fail 5). Windows 10 21H2 AMD64 + dotnet-sdk-8.0.100-rc.2.23472.8: Fail

Verified with the latest RC2 coherent build dotnet-sdk-8.0.100-rc.2.23477.19, the issue has fixed and does not repro.
