My VS instance crashed while I was trying to add a WCF service. Had to terminate the process. But when I restarted, I noticed strange behaviours with the IDE. I could no longer debug my project and would receive an error stating that "The breakpoint will not currently be hit. No symbols have been loaded for this document."
A bit of googling found this article.
The solution for me was to:
1. start debug
2. ctrl+alt+u.
3. Look for project in list and note path.
4. Close VS.
5. In explorer navigate to cache location in step 3, delete location of the cache usually under C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\xxx
I just deleted everything in root.
6. Deleted both bin and obj folder of each project.
6. Restart VS
7. Rebuild
