Hi, thanks for reporting!

This is a known dotnet-format issue:
dotnet/format#1546

It sadly does not seem like there will be a fix soon (the issue was opened over 1 year ago, closed in the meantime, but now the problem occurs again).

As a workaround, you can remove any <EnforceCodeStyleInBuild>true</EnforceCodeStyleInBuild> directive from your *.csproj files. This seem to work fine according to the comments in the original issue.

[flobernd]

Another workaround is mentioned here:
dotnet/format#1805 (comment)

This involves downgrading the SDK to 7.0.1xx.

[slaterx]

Neither of those worked unfortunately. The hardest part is not knowing what triggers the issue. It started for us out of the blue two days ago...

[flobernd]

@slaterx Would it be possible to share (one of) your *.csproj file(s)? Otherwise it's hard for me to reproduce it. And please paste me the output of dotnet --version executed in the same directory as your solution.

Another option would be to pull the latest standalone version of dotnet-format and use this one instead of the one bundled with the SDK. The bug seems to be fixed upstream. I'm open to add such option to the action.

Edit: The above workaround does not seem to work either.

@slaterx

The hardest part is not knowing what triggers the issue.

The issue is triggered by a .NET SDK update on the GitHub runner images. They do now ship version 7.0.302 which contains a buggy version of the dotnet-format tools. The most recently working version seems to be 7.0.103.

I published v1.1.0 of the action which introduces the use-standalone-tool input. This can be set to use the standalone version of dotnet-format. The latest version 8.0.426908 contains a bugfix for the issue (but this version is not yet shipped with the current .NET 8 SDK and won't probably get backported to the .NET 7 SDK).

The CI workflow has been adjusted to make use of this option (installs the .NET 8 SDK, installs the latest dotnet-format standalone tool and sets the use-standalone-tool input):
https://github.com/zyactions/dotnet-lint/blob/master/.github/workflows/ci.yml

Note that all other dotnet commands will still honor the global.json and use 7.0.103 (in my case).
