MVC MiniProfiler with Entity Framework 5 Model First Error: Unable to determine the provider name

1

See case on http://stackoverflow.com/q/13959820/51.

Using Entity Framework 5, MiniProfiler 2. Nuget installed for MiniProfiler.EF.

Creating a connection as follows

var conn = new EFProfiledDbConnection(DbConnections.GetSqlConnection(),                                                                      MiniProfiler.Current);
return new MyDbContext(conn, true);

When trying to retrieve data using the DbContext, the following error is returned:

Unable to determine the provider name for connection of type     
'StackExchange.Profiling.Data.EFProfiledDbConnection'.`

Tried using the MiniProfilerEF.Initialize() functions, and setting the ProfiledDbProviderFactory in Web.config, but nothing helps.

How can this be fixed? Is MiniProfiler working for EF5 model first?
