Make private .NET Framework method public?

Hi,

I just got this message, when refactoring some older code.
I previously had a custom ParseHelper.TryParseGuid, but after converting to .NET 4.0 I would change it to the new Guid.TryParse.
What I noticed was ReSharper trying to make the private method Guid.TryParseGuid public, which I thought was a bit pointless, as it's not possible.

I've attached a screenshot to illustrate my point.
