Re: #24966- "Private field x is never assigned" diagnostic when properties can set
From your code snippet, the variable _rateTag is never assigned (I.E. the instance _rateTage of type Location is never created).

If the Location type is a class, calling the property getter or setter will result in a NullReferenceException. In this case R# is correct in its diagnostic.

If the Location is a struct, calling the property getter or setter is valid and R# (build 241) correctly parses the file as containing no errors.

Sorry, I should have mentioned that Location is indeed a struct.

I'll try this code with build 241.

I see the same result with 241. Unfortunately, I'm not able to dupe with a simple program.
