    string.IsNullOrEmpty(myStr) has always annoyed me, why isn’t it an extension method or a non-static method?

    myStr.IsNullOrEmpty() just feels cleaner and more intuitive to me.

      The usual convention is to have extension methods behave like regular methods, I.E. don’t allow them to accept nulls. When looking at foo.Bar(); it’s better if I can just intuit that foo can’t be null because you’re not supposed to be able to invoke the . operator on null.

      Of course, I’m entirely guilty of breaking this rule myself. cough Shoudly cough FluentAssertions cough
