Resharper newb here - it's entirely possible i've manged to do something really dumb.
We have a large solution. Since installing SP1 I can open a c# source file, and Resharper will tell me that a reference (using) is not needed. Further on in the source it's reporting "Cannot resolve symbol" for types from that assembly.
The project reference itself is fine.
And the build succeeds.
I guess i can supply screen shots if it helps?
