[HttpStress] [SslStress] Windows stress builds are broken

The failures started on the 17th of November, across all branches, which indicates an image change might have triggered this, we should do a comparison similar to #82528 (comment).

I encountered this on my dev machine. The VS installation needs to be updated, see #94998 (comment)

[antonfirsov]

This is weird, the Initialize job phase logs that

Image: windows-2022
Version: 20231126.1.0
Included Software: https://github.com/actions/runner-images/blob/win22/20231126.1/images/windows/Windows2022-Readme.md

and according to the linked image spec the Visual Studio version is 17.8.34316.72, which should contain the fixed 14.38 C++ runtime tools according to #94998 (comment).

@dotnet/dnceng can you please assist diagnosing this?

[rzikm]

The image seems to contain the right msvc version, but the build script for some reason does not choose the latest toolchain

I wonder what will happen if you manually delete the <=14.37.32822 directories?

then it tries to use GCC 🤦

Okay, I think I have spent enough time on this and am just trying at random, I think we need help from @dotnet/dnceng to debug this. Can you please take a look?

[markwilkie]

@rzikm - what are you hoping dnceng can help with more specifically?

[rzikm]

we are running the sslstress pipeline on 1es-windows-2022-open images, as such, we need first to build the .NET runtime and then build the stress application against it and run it in docker.

Since November, the build has been failing due to #94998, the fix for that was supposed to be updating Visual Studio installation.

According to the list of included software of the image, the new toolchain is installed and seems to shows up in the relevant directories

However, the build still ends up using the older toolchain, and thus failing to build

 -- The CXX compiler identification is MSVC 19.37.32826.1

The failing step is simply building the SDK docker image via the build-docker-sdk.ps1 -w ....

@rzikm - what are you hoping dnceng can help with more specifically?

We are hoping that dnceng would help us get the build to work, since we are using the "official" script to build the image.

(note that the .net runtime is being built on the host, not inside docker image due to #700)
