This morning, when opening Visual Studio 2012 I see lots of "red code" based around "Cannot resolve symbols". The code compiles and runs fine. I am using Resharper, so not sure if it is an issue with RS?
I did have an issue with my laptop OS over the weekend with a display adapter and windows update corrupting it. I am running windows 7. I did do a restore, but only back a 2 days.
I have closed all files, restarted VS2012 and still not joy.
What do you think might have gone wrong?
Many thanks in advance.
EDIT:
sorted: ReSharper "can not resolve symbol" even when project builds
