Description

I am getting error while building main and release/8.0-staging branch of runtime.
error C3611: 'System::Numerics::INumberBase::System::IUtf8SpanFormattable.Try Format': a sealed function cannot have a pure-specifier

Can somebody help me finding a solution for that.

Reproduction Steps

1. git clone https://github.com/dotnet/runtime.git -b release/8.0-staging
2. .\build.cmd clr+libs -c release -a x64

Expected behavior

It should be compiled.

Actual behavior

@tannergooding Do we need to update the minimum VS version required to build the repo in https://github.com/dotnet/runtime/blob/main/docs/workflow/requirements/windows-requirements.md#visual-studio ?

[tannergooding]

Do we need to update the minimum VS version required to build the repo in

Probably. Notably, it's not kept up to date as is. New versions of Roslyn only work "correctly" with the latest IDE and so we've already "required" VS 17.8 to work with parts of the codebase for months, but the doc still says 17.3

I'll submit a PR updating that and the C++/CLI tools version

[tannergooding]

I've put up #95018.

The issue is the same as described in #94723. C++/CLI required a fix to work with a previously unused aspect of Default Interface Members (DIMs). This fix only exists in v14.38 or higher and so VS2022 17.8 or later is required to build those projects currently.

Can we also update the .vsconfig file? or is that unnecessary?
