sdk warning on nuget package Microsoft.CodeAnalysis.CodeStyle

[elachlan]

I followed all the instructions for installing and starting VS from a script, but I get 91 of the errors below. I do have ,Net 4.8 installed from VS installer but where do I get new compiler?

Severity	Code	Description	Project	File	Line	Suppression State
Warning	CS9057	The analyzer assembly 'C:\Users\PaulM\Source\Repos\winforms\.dotnet\sdk\8.0.100-preview.7.23376.3\Sdks\Microsoft.NET.Sdk\codestyle\cs\Microsoft.CodeAnalysis.CodeStyle.dll' references version '4.8.0.0' of the compiler, which is newer than the currently running version '4.7.0.0'.

@lonitra created the issue. Does the team want to remove the package and use the SDK version of the analyzers?

@paul1956 - what version of the VS are you on?

[elachlan]

@Tanya-Solyanik do we need VS preview? I get these warnings in VS 2022 17.7.3

@paul1956 - what version of the VS are you on?

Microsoft Visual Studio Community 2022 (64-bit) - Current Version 17.7.3

I used below from PowerShell to start Visual Studio.

.\start-vs.cmd

I also have the current preview Microsoft Visual Studio Community 2022 (64-bit) - Preview Version 17.8.0 Preview 1.0
but don't know how to start it with the included script as it always starts the production version.

You need to right click on any sln file and set the newer version of VS as the one to open "sln" files. Then the script will open the solution in that instance of VS.

@paul1956 is this solved by launching with the correct developer command prompt?

[paul1956]

@merriemcgaw both solutions above work to start the prerelease version of VS. The original issue about sdk warnings is not solved in production release, it is solved in prerelease.
Thanks.
