I can’t figure out what Re# is complaining about with a piece of code. Everything compiles ok and works as it should, but Re# can’t seem to resolve the expression without offering any suggestions. Look at the attachment for code and error.
Any offers?

Your code is fine. This was a bug in Resharper, now fixed in version 5.1.
Had the same warning all over the place (to the extent I turned off Re# until I got the 5.1 update). Ours was also a Silverlight 4 app.
Re# 5.1 behaves a lot better with VS 2010 now. Clashes with intellisense autocomplete have also vanished.
