Title Body

I'm trying to use the mvc-mini-profiler with EFCodeFirst I'm creating a DbProfiledConnection and passing it to the DbContext on construction as below. The application continues to work as expected by the sql is not exposed to the Profiler. public class WebContext : DbContext { static DbConnection _connection = new SqlConnection(ConfigurationManager.ConnectionStrings["WebContext"].ConnectionString); static DbConnection _profiledConnection = MvcMiniProfiler.Data.ProfiledDbConnection.Get(_connection); public WebContext() : base(_profiledConnection, true) { } oops my bad. I've modified it so that when my WebContext is constructed in my UnitOfWork i pass in a ProfiledDbConnection public UnitOfWork() { var profiledConnection = MvcMiniProfiler.Data.ProfiledDbConnection.Get(connection); this.context = new MyContext(profiledConnection); } I've checked and MiniProfier Current has been set in Application_BeginRequest and it returns a ProfiledDbConnection when I then try and query the database an error is thrown in the ProfiledDbProviderServices class. protected override string GetDbProviderManifestToken(DbConnection connection) { return tail.GetProviderManifestToken(connection); } this method returns a "The provider did not return a ProviderManifestToken string." error
