error C3611: 'System::Numerics::INumberBase::System::IUtf8SpanFormattable.TryFormat': a sealed function cannot have a pure-specifier

Description

I am getting this error while building the c++/cli project in Azure Pipeline.

Error I am getting: error C3611: 'System::Numerics::INumberBase::System::IUtf8SpanFormattable.TryFormat': a sealed function cannot have a pure-specifier

Task: VSBuild@1
UseDotNet@2 (version): 8.0.x
vmImage: 'windows-2022'

I have gone through the existing defect dotnet/runtime#94998. Here the solution states that we have to use v14.38 or higher and so VS2022 17.8 or later. As I am using Microsoft hosted agent machine (windows-2022), all the required tools are installed, but still it is failing to build the project.

Could someone please help me to resolve this issue.

Hello @NaveenVNaik , do you have repro steps, maybe some minimal project publicly available ?

Hi @ilia-shipitsin , I cannot share the code as it is in my companies private repo.

Hello, @NaveenVNaik

In the issue mentioned by you is said that VC toolset 14.38 is required.
That toolset is included into current windows images.

As there're several toolsets included, VSbuild@1 task may pick either of them. For more diagnostic, please add '-bl' flag to msbuildArgs, it will produce binary log (file msbuild.binlog).

Can you please collect msbuild.binlog via following task

- task: PublishBuildArtifacts@1
  condition: always()
  inputs:
    PathtoPublish: '$(Pipeline.Workspace)\msbuild.binlog'
    ArtifactName: 'msbuild.binlog'
    publishLocation: 'pipeline'

Hello @ilia-shipitsin,

The issue is resolved. We have to set the MSVC toolset version to 14.38 in C++/CLI project properties.
[ Configuration Properties -> Advanced -> MSVC Toolset version -> 14.38 ]

There is no issue with windows current image.

Thank you for looking into it. !
