我正在使用ASP.Net MVC 3和Entity Framework代码优先构建的项目中使用mvc-mini-profiler.

一切都很有效,直到我尝试通过ProfiledDbConnection在文档中描述的方式包装连接来添加数据库分析.由于我使用的是DbContext,因此我尝试提供连接的方式是使用静态工厂方法构造函数:

public class MyDbContext : DbContext
{                
    public MyDbContext() : base(GetProfilerConnection(), true)
    { }

    private static DbConnection GetProfilerConnection()
    {
        // Code below errors
        //return ProfiledDbConnection.Get(new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionName"].ConnectionString));

        // Code below works fine...
        return new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionName"].ConnectionString);
    }

    //...
}

使用时ProfiledDbConnection,我收到以下错误:

ProviderIncompatibleException: The provider did not return a ProviderManifestToken string.
