咳咳。

过了一会儿，试图找出这一个，我马上回起点，开始质疑我的假设。通常在这种情况下，如果没有人似乎有一个答案，我做的事情真的很密集。

After a while trying to figure this one out, I got right back to the start and began questioning my assumptions. Usually in this kind of situation if nobody seems to have an answer I am doing something really dense.

果然，我有几个班在我的Web服务文件（因为它是一个用于测试的存根，并不会在长期使用），我已经完全在我的.asmx文件作为Web服务的支持代号为错误的类。

Sure enough, I have a couple of classes in my Web Service file ( because it's a stub for testing and will not be used in the long term ) and I had completely the wrong class named in my .asmx file as the supporting code for the web service.

在我纠正了，一切正常。

Once I corrected that, everything worked fine.

我不感到自豪，这是远从我最自豪的时刻，但我会为了以防万一有人离开这个否则运行到同样的问题...

I'm not proud, it's far from my proudest moment, but I'll leave this just in case anyone else runs into the same problem...
