I've built a very simple web service which builds with no errors. I can navigate to it in a browser, which shows me a list of the available methods. I can select one of those methods, which displays a screen with some detailed information about the method. Then if I click to run the method, I get, "File or assembly name mfdzszl4.dll, or one of its dependencies, was not found." where 'mfdzszl4' is a random string of characters that changes every time I click to run the method. Anyone seen this before?
