无法使用Enity Framework 4.0设置MiniProfiler(不是代码优先)

Question

我通过nuget在我的项目中安装了MiniProfiler和MiniProfiler.EF.

在使用MiniProfiler之前,我会在我的模型库中使用它来打开一个连接:

    public class NotificationRepository
    {
       private CBNotificationModel.CB_NotificationEntities db;

       public NotificationRepository()
       {
          db = new CB_NotificationEntities();
       }

       public NotificationContact GetNotificationContacts()
       {
          return db.NotificationContacts.ToList();
       }
    }

要使用我创建的迷你探查器:

  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);
        }
    }

模型库现在使用

db = ConnectionHelper.GetEntityConnection();

但是这会给出错误:

mscorlib.dll中发生了未处理的"System.StackOverflowException"类型异常

我错过了一步吗？我尝试在Application_start()中添加MiniProfilerEF.Initialize()和MiniProfilerEF.Initialize_EF42(),但这只会更改给定的错误.

设置实体框架项目以使用miniprofiler似乎没有太多信息,除非它是代码优先的.

我通过将ConnectionHelper类更改为以下内容来实现此功能:

    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;

          }
     }
