dotnet format is broken on sdk 8.0 preview

[froissant]

Running dotnet format is broken on sdk 8.0 preview.
This is similar to #1800.

Reproduction steps

This was reproduced on fresh installs on multiple machines, all running Ubuntu 22.04 under WSL2

• Install the latest dotnet preview (8.0.100-preview.6.23330.14)
• Create a new project with dotnet new webapi
• Run dotnet format on the created project

Expected

dotnet format runs on the project without errors

Actual

The process errors out with the following log:

Additional information

It was also broken on sdk 8.0.100-preview.5.23303.2

[sharwell]

This was fixed by #1885

[froissant]

Thanks @sharwell for the info, will it be included in preview 7? Because at the moment, in preview 6, it's still broken on my machines (even with a fresh install on a new machine without any other versions of dotnet or in Windows Sandbox)

[sharwell]

I'm not sure how/when the SDK updates and packaging occur. The fix was first included in 8.0.432702.

Looking at the version info in the preview 7 branch (https://github.com/dotnet/sdk/blob/release/8.0.1xx-preview7/eng/Version.Details.xml#L73-L77), it appears the build should contain #1885.

[froissant]

Great, thank you! Now I know where to look for this info 🙂

[froissant]

Can confirm that I have no errors anymore with .NET 8.0.0 Preview 7! ❤

[JoeRobich]

@froissant Thanks for confirming!

When trying to build the project, I am encountering errors on preview 7. Here is the environment information:
Windows 11 Pro
Visual Studio 2022 17.7.0
SDK 8.0.100-preview.7.23376.3
However, if I run "dotnet build --configuration Debug" from the CLI, there are no issues.
