WCF will not return an int

Question

I am building a WCF in C#, and a client to consume it at the same time. For some reason I am having trouble getting a method to return an int. Here is my contract:

Answer 1

You import it as a Service Reference (with name space MData) instead Web Reference.

And use the below code,

MDataClient m = new MDataClient(); 
String helloWorld = m.HelloWorld(); 
int result = m.ReturnAnInt();

There is nothing wrong in your code. It should works fine if you add Service Reference and use the above snippet.
