RIA服务初始化问题
我在使用 RIA 服务时遇到问题。有时（并非总是）我收到 InvalidOperationException 并显示消息：“EntityTypes 已被初始化”
该错误来自生成的文件，但我不知道如何解决此问题。谷歌只给出了 2 个结果，这不是很有帮助。
有谁知道我可以做什么来解决这个问题或者我可以尝试什么？
问候
I have a problem with RIA services. Some times (not always) I get an InvalidOperationException with the message: "EntityTypes has already been initialized"
The error comes from the generated file but I don't know how to resolve this issue. Google brings out only 2 results which are not very helpfull.
Does anybody know what I could do to solve this or what I could try?
Regards

我现在找到了解决方案。
设置断点后，我注意到我从不同的线程调用了两次相同的方法。
我的理论：他们同时访问相同的域服务查询，但由于某种原因这是不可能的。这也解释了因为此错误只是偶尔发生。
由于我修改了代码，因此该方法不会被调用两次，一切都运行良好。
希望这对某人有帮助...
I found now a solution.
After setting a breakpoint I noticed that I called two times the same method from different threads.
My theory: they accessed the same Domain Service query at the same time and this is for some reason not possible. This explains also because this error happens only sporadically.
Since I modified my code that this method is not called two times everything works perfectly.
Hope this helps someone...
