RESTful WCF returns 400 Bad Request and more

Client will get a 400 Bad Request response when the return type from the method signature does not match the type of the returned result.

For example,

public Object DoWork()

{

return 12;

}

 

Why IEnumerable<T> cannot be used as the return type?

Because IEnumerable (and other interfaces) are not expressible in XML schema. Using a concrete type works fine in this case.
