I have a colleague who has installed Resharper successfully (apparently) and successfully opens our standard solution in VS (c#) consisting of about 20 projects.
However when he opens up a source file, resharper identifies any types (including the System types) in red and states it cannot resolve the symbol (or something to that effect - he's locked his computer for the day - so I can't verify).
He is only running two other add-ins - one's Test Driven.NET and another an internal add-in which we all run.
It is a bit confusing, but I suspect something in the install didn't get setup correctly.
Have you any suggestions ?
