A continuation of previous post.
1) Visual Studio, publish web service: check destination IIS app
Before the change, the error was “cannot show the content of the folder”.
2) Add this line to the service.cs (service class C# file), to work around/avoid a problem, asp .net compatibility issue. Do something like this:
class BarService : IHelloContract
Refer to wenlong
3) Bad request: it appears to be a class rename problem, Visual Studio has a “red” warning sign, follow it and accept “update”, rebuild.
