I've tried setting <LangVersion></LangVersion> in vbproj file with the following values and it seems to not be passed to the IDE or the Compiler via the VS2017 Experimental Instance.

15.3
15.5
Latest

As a result I am unable to test / try out my changes.
Note: The Unit Test is working correctly (well it indicate that it passes). (see [unittest](https://github.com/dotnet/roslyn/pull/26865/files#diff-b5061195acc1fa28a4ef716754f4b9d5)), Though I am directly setting the language version.

I would help if we enabled the following project feature for VB.net as well to add How-to-change-targeted-Csharp-version-in-Visual-St

I've set Latest in vbproj file and it is being passed to the IDE or the Compiler via VS2017.

Not sure what bug you are reporting here. You've indicated the project file contents correctly pass to the compiler.

@jaredpar Sorry I didn't realise that I had miss wrote the original issue. dyslexic I've updated it.
It is this feature check, that is returning false. The DirectCast(expr.SyntaxTree, VisualBasicSyntaxTree).Options.LanguageVersion is version 15 no matter how I change the LangVersion in the vbproj file.

[jaredpar]

Can you provide the vbproj file where you use latest?

[AdamSpeight2008]

@jaredpar It's it that same except for the 15.5 is Latest. Also updated the post.

@AdamSpeight2008 Why does the vbproj in the first post specify <LangVersion> twice?

@jaredpar

What I've set in the .vbproj

What VS says I've used.

@jaredpar Narrowed down the issue. I'm using VisualStudioSetup and isn't using the correct value.
