Entity Framework: Why SimpleMembership looking for Default Connection - asp.net-mvc

Question

I have explicitly set AccountsContext to use mytestdb as the connection string for SimpleMembership, as below -
public class AccountsContext : DbContext
{
public AccountsContext()
: base("mytestdb")
{
}
}
But Database initialized in following line of code is still looking for DefaultConnection for some reason. Although I have removed reference to DefaultConnection completely from web.config.
public sealed class InitializeSimpleMembershipAttribute : ActionFilterAttribute
{
private static SimpleMembershipInitializer _initializer;
private static object _initializerLock = new object();
private static bool _isInitialized;
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
// Ensure ASP.NET Simple Membership is initialized only once per app start
LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
}
}
Here is the Web.config file with commented sections -
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<!--<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />-->
</configSections>
<connectionStrings>
<add name="mytestdb" connectionString="Data Source=(local);Initial Catalog=mytestdb;User ID=****;Password=****" providerName="System.Data.SqlClient" />
<!--<add name="DefaultConnection"
connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-LakshyaMvc-20130205074346;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-***.mdf"
providerName="System.Data.SqlClient" />-->
</connectionStrings>
<!--<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
</entityFramework>-->
Any help in this regard will be much helpful.

Take a look at the SimpleMembershipInitializer private class inside the ~/Filters/InitializeSimpleMembershipAttribute.cs file:
private class SimpleMembershipInitializer
{
public SimpleMembershipInitializer()
{
Database.SetInitializer<UsersContext>(null);
try
{
using (var context = new UsersContext())
{
if (!context.Database.Exists())
{
// Create the SimpleMembership database without Entity Framework migration schema
((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
}
}
WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
}
catch (Exception ex)
{
throw new InvalidOperationException("The ASP.NET Simple Membership database could not be initialized. For more information, please see http://go.microsoft.com/fwlink/?LinkId=256588", ex);
}
}
}
Do you notice the following line:
WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
That's where it is coming from. By the way if you had looked at the exception stacktrace you got it would have pointed you to this location.
Also in the ~/Models/AccountModel.cs file you might have the following context defined by default:
public class UsersContext : DbContext
{
public UsersContext()
: base("DefaultConnection")
{
}
public DbSet<UserProfile> UserProfiles { get; set; }
}
