“Object has been disconnected or does not exist at the server” exception

Question

I need to use cross-appdomain calls in my app, and sometimes I have this RemotingException:

Object \'/2fa53226_da41_42ba_b185_ec7d9c454712/ygiw+xfegmk

Answer 1

In my case, this was happening with SQL LocalDB stored in App_Data folder inside Web project. Whenever I try to use Package Console to run update-database to init my Entity Framework database using migrations, nothing happens. Then after a while, I get that error.

I solved this by revising file permissions on App_Data. Once fixed, voila, it worked.
