Notes: Apologies for the non-minimal repro, as I’m not sure what’s causing this in the first place. Additional apologies if this belongs in roslyn-analyzers instead of this repo. I didn’t see anything related to CAxxxx, so I’m assuming this belongs here.

We have the same issue in github actions. The same commit yesterday had passed dotnet format --verify-no-changes, but today it failed with

I am getting this issue but for 4.5.0.0 in .NET 7.0.202.

For those running into this problem. The following worked for me. Use the dotnet-format standalone tool instead of the one bundled into dotnet.

dotnet tool install -g dotnet-format --version "7.*" --add-source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet7/nuget/v3/index.json

Invoke with dotnet-format

For other versions of dotnet (6, 8, etc). Change the version and source: ex:

dotnet tool install -g dotnet-format --version "6.*" --add-source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet6/nuget/v3/index.json

This was sufficient for me, you may need to look for a specific version of the tool if this doesn’t work for you.

I got the same issue but (temporarily) resolved it by removing <EnforceCodeStyleInBuild>true</EnforceCodeStyleInBuild> from my .csproj.

jerohero on Mar 28, 2023

Just encountered the same issue with the .NET 7 SDK while running dotnet-format in a GitHub Action workflow. Any comment from official side here?

flobernd on Apr 27, 2023

I switched to Rust and everything worked perfect since then.

On the topic: just wait or use LTS versions of .NET.

slonopotamus on Jun 5, 2023

Same for me with .NET 7 SDK

dnaprawa on Jun 2, 2023

@OoLunar There is a fix coming in the next .NET 6 SDK release. In the meantime you can install dotnet format as a global tool to work around this issue (See https://github.com/dotnet/format/issues/1519#issuecomment-1055922333). Closing this issue as duplicate of https://github.com/dotnet/format/issues/1519

JoeRobich on Apr 4, 2022

Unfortunately I cannot do this as I’m on Linux and use Visual Studio Code. Are there any alternatives I can do?

Edit: I failed to read. Will attach the binlog in a moment

The fix for the current SDKs will be in the next servicing release of the SDKs. Sorry the infrastructure that updated the Roslyn version fell behind.

JoeRobich on Jun 1, 2023

@JoeRobich we have similar problem (just version is 4.6.0.0 instead of 4.1.0.0) on github actions with 7.0.302 version. Should this issue be reopened?

I got the same issue but (temporarily) resolved it by removing <EnforceCodeStyleInBuild>true</EnforceCodeStyleInBuild> from my .csproj.

This also fixed the problem for me, though I’m not sure why. I don’t understand why this would be a problem.
