Msbuild failed: Newtonsoft.Json, Version=13.0.0.0

[chanakya-svt]

I am using a code analysis tool called Roslynator. After upgrading to .NET6, I am getting the following error when I run analysis on the solution.

I was directed to here by the author of Roslynator based on the discussion

Following is the error I am facing:

Environment: .NET: v6.0 OS: macOS Montery v12.2 Example repo: https://github.com/chanakya-svt/RoslynatorTest

Steps to Reproduce:

1. Clone the above repo and restore
2. install roslynator command line dotnet tool install -g roslynator.dotnet.cli
3. run roslynator analyze -v diag

Note: The same setup works without an errors for .net5.0

Please redirect if this is not the correct place for this issue.

Are there any news? I'm also stumbling over this problem.

Does this use MSBuildLocator at all? From what you're doing, it looks like you need to.
