I am developing a code first web app in Visual Studio 2012 Express.

I use this connection string in the web.config:

```
<add name="myContext" connectionString="Data Source=.;Integrated Security=True;Initial Catalog=cityKingMVC4" providerName="System.Data.SqlClient" />

```

I am using SimpleMembership.

I am trying to seed 1 administrator from Filters/InitializeSimpleMembershipAttribute.cs:
...

```
WebSecurity.InitializeDatabaseConnection("myContext", "Users", "UserId", "Email", autoCreateTables: true);

// A: Create Admin user
if (!WebSecurity.ConfirmAccount("admin@mydom.com"))
{
   WebSecurity.CreateUserAndAccount("admin@mydom.com", "password");
}

// B: Create admin role if not exist
if (!Roles.RoleExists("Administrator"))
{
   Roles.CreateRole("Administrator");
   Roles.AddUserToRole("admin@mydom.com", "Administrator");
}

```

If I comment A & B it doesn't crash. If I don't I get this:
The "WebSecurity.InitializeDatabaseConnection" method can be called only once.

If I debug and put a breakpoint on 'WebSecurity.InitializeDatabaseConnection' - it only calls it once and there is no other code calling WebSecurity.InitializeDatabaseConnection anywhere.

If I debug - it crashes on a different line higher up in the file (standard SimpleAuthentication file):
LazyInitializer.EnsureInitialized(ref \_initializer, ref \_isInitialized, ref \_initializerLock);

with this error:
Exception has been thrown by the target of an invocation.

Stack Trace:
