I know this has been asked before, but there was no solution to the problem, and it was last year, so I thought maybe someone has found something to solve this by now. I am using VS2010 with SP1. before installing the SP1 there was no problem. if I uninstal re# it works fine. I have an ASP.Net website and some other projects. The classes from the other projects are not recognized, resharper suggests using the other project, so I do so, it puts it up at the usings, then the using also gets a "cannot resolve symbol". I have tried the suggestions they gave in 2011 here but nothing. if I delete the _Resharper. and restart vs, it will work for 5 seconds, then all red again...
hope someone found a solution to this since then...thanks
Edit: I have noticed it does this with Web Services
Although this question is rather old it happended to me today. I solved it by going to menu
Tools -> Options -> ResharperClick on
Optionsand pressClear Cachesbutton followed bySave.Then just click on the
Suspend Nowfollowed byResume Nowbutton to restart Resharper and your code should be ok again.EDIT: happened to me again. Clearing caches helped. The only thing changed is that "Clear caches" is hidden under General tab in resharper options.
