When I try to run my ASP.NET MVC 4 application using Local IIS on Windows 7 with Visual Studio 2013. I run into the following error when the application tries to connect to localDB\v11.0
Server Error in '/' Application.
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not
found or was not accessible. Verify that the instance name is correct
and that SQL Server is configured to allow remote connections.
(provider: SQL Network Interfaces, error: 50 – Local Database Runtime
error occurred. Cannot create an automatic instance. See the Windows
Application event log for error details. )The 2 event logs are
Unexpected error occurred while trying to access the LocalDB instance
registry configuration. See the Windows Application event log for
error details.and
Cannot get a local application data path. Most probably a user profile
is not loaded. If LocalDB is executed under IIS, make sure that
profile loading is enabled for the current user.
Most solutions I found online references this post: http://blogs.msdn.com/b/sqlexpress/archive/2011/12/09/using-localdb-with-full-iis-part-1-user-profile.aspx
The only difference I see between the described situation and my situation is that the described error code is 0 whereas my error code is 50. However, the proposed solution does not work for me.
I cannot get past this error even if I set modify setProfileEnvironment to true and I've spent hours of time playing around with different processModel parameters and application pools.

I was also suffering from same problem, but there is a solution for it.
Go to the IIS server, and then to the application pool from which your application is running. In the advanced settings of the application pool there is a "Process Model" option, under which there is an "Identity" option. This is by default the application pool identity. Change it to Local System, and you're done.
And Remember to Put App_Data Folder their in WWW folder of IIS server
