What does this implement/fix? Explain your changes.

This occured in trying to use F# code from Python. As the .Name property returns null, ContainsKey fails.

Does this close any currently open issues?

I don't think so.

Any other comments?

I don't know if there is a way to create a C# method without a parameter name. I'll try to set up a few simple F# test-cases in the future in a separate PR (follow-up ticket: #1374).
