I am getting this Exception When I am trying to access database from C#.
My Connection String is
Data Source=(localdb)\\v11.0;integrated security=tr
Just to add some more information. If some how this doesn't work for you and it still complains that its not able to locate server. You will be required to set following two attributes on your application pool identity in applicationHost file
where these two attributes are required to make sure your account can start LocalDB server.
