Dotnet format fails with EnforceCodeStyleInBuild enabled in 7.0.200

Describe the bug

When running dotnet format with .NET SDK 7.0.200 and EnforceCodeStyleInBuild, I get an error of Microsoft.CodeAnalysis 4.5.0.0 not being found. This works however on .NET SDK 7.0.103. It looks like the version of the Microsoft.CodeAnalysis within dotnet-format is incorrect (shipped with 4.4.0 while the SDK is expected 4.5.0), and additionally 4.5.0 is yet to be released on nuget.

To Reproduce

A new project with the csproj modified to have the property <EnforceCodeStyleInBuild>true</EnforceCodeStyleInBuild>. Here is a sample:

Did this solve the issue for you? I’m having the exact same issue, but was unable to resolve it by installing the Microsoft.CodeAnalysis.CSharp v4.5.0 package as suggested. The only solution so far has been to pin the SDK to 7.0.103.

I’m also stuck at 7.0.103 at the moment. Installing Microsoft.CodeAnalysis.CSharp v4.5.0.0 in every project is not a valid solution. At 7.0.103 dotnet format works without that.
