调查AmbiguousMatchException

Question

我正试图找到一个AmbiguousMatchException的底部，我已经完成了代码审查，但它还没有发现任何有用的东西。

我认为这与此EF错误有关 - Can't map two classes with same name from different namespace并且已经进行了代码更改，这可能会导致自上次部署以来的问题。我试图将对象添加到实体，只是;

var request = new ApplicationRequest
{
   Name = "Test Application"
   // ... many more Properties
};
var context = new DataContext();
context.ApplicationRequests.Add(request);

挖掘返回的调试对象，但找不到任何链接到导致问题的实际类型或属性名称的内容。

我的调用堆栈提供的信息很少;

在 context.ApplicationRequests.Add（request）;

之前在即时窗口中运行GetType

applicationRequest.GetType();
{Name = "ApplicationRequest" FullName = "EntityModel.ApplicationRequest"}
    [System.RuntimeType]: {Name = "ApplicationRequest" FullName = "EntityModel.ApplicationRequest"}
