Unable to setup MiniProfiler w/ Enity Framework 4.0 (Not code first) - asp.net-mvc-3

Question

I installed MiniProfiler and MiniProfiler.EF in my project via nuget.
Before using MiniProfiler I would open a connection using this in my model repository:
public class NotificationRepository
{
private CBNotificationModel.CB_NotificationEntities db;
public NotificationRepository()
{
db = new CB_NotificationEntities();
}
public NotificationContact GetNotificationContacts()
{
return db.NotificationContacts.ToList();
}
}
To use mini profiler I created:
public static class ConnectionHelper
{
public static CB_NotificationEntities GetEntityConnection()
{
var conn = new StackExchange.Profiling.Data.EFProfiledDbConnection(GetConnection(), MiniProfiler.Current);
return ObjectContextUtils.CreateObjectContext<CB_NotificationEntities>(conn); // resides in the MiniProfiler.EF nuget pack
}
public static EntityConnection GetConnection()
{
return new EntityConnection(ConfigurationManager.ConnectionStrings["CB_NotificationEntities"].ConnectionString);
}
}
The model repository now uses
db = ConnectionHelper.GetEntityConnection();
However this gives the error:
An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll
Am I missing a step? I tried adding MiniProfilerEF.Initialize() and MiniProfilerEF.Initialize_EF42() in Application_start() however that just changes the errors given.
There does not seem to be much information for setting up a entity framework project to use miniprofiler unless it is codefirst.

Answer 1

I was able to get this working by changing my ConnectionHelper class to the following:
public static class ConnectionHelper
{
public static CB_NotificationEntities GetEntityConnection()
{
var connectionString = ConfigurationManager.ConnectionStrings["CB_NotificationEntities"].ConnectionString;
var ecsb = new EntityConnectionStringBuilder(connectionString);
var sqlConn = new SqlConnection(ecsb.ProviderConnectionString);
var pConn = new StackExchange.Profiling.Data.EFProfiledDbConnection(sqlConn, MiniProfiler.Current);
var context = ObjectContextUtils.CreateObjectContext<CB_NotificationEntities>(pConn);
return context;
}
}
