I've managed to get my database into a knot. I was altering a LINQ to SQL dbml file in visual studio. I ran up the application and next thing all subsequent queries fail. Also I can't expand any of the stored procedure folders in ANY database. I keep getting the above error. I see lots of posts to the effect...try re-running the query with without the NOLOCK hint or whatever. What query??? I didn't run a query.
I dropped every database except the system databases. Same error.
I rebuilding the system data. Same error!!!
Is there any way out of this nightmare?
