I have suddenly started getting an error in my asp.net MVC 4 web application.
The error is:
This operation requires a connection to the 'master' database. Unable to create a connection to the 'master' database because the original database connection has been opened and credentials have been removed from the connection string. Supply an unopened connection.
var filteredContacts = dc.EAContactLists.Where(o => teams.Contains(o.Team)).ToList();
Persist Security Info = True in your connection string.
Hope this helps.
