That is an urban myth, CLR was designed with support for C++ in mind.

Also Go is at the stage of C# .NET 2.0, and still plenty of lacking language features.

I really think the creator of C# made a disservice to the .NET community by picking Go for the Typescript rewrite.

Go still has a better deployment story. Single static binary deployment are king. On .Net 8 I was hitting random compatibility issues with single binary application bundles, with System.Data.SQLite, and other libraries. (had to use that one and not he Microsoft one for some legacy compatibility reason, maybe around Guid handling maybe)
