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

I had a similar issue, I could not get an out int parameter of my web service to work. I am still not sure due to what this was exactly, but I had it working using a string as out parameter.

[OperationContract]
LoginStatus GetLogin(string username, string password, out string s_uId);

on the web service side:

s_uId = uId.ToString();

on the client side:

int uId;
string s_uId;
result = client.GetLogin(username, password, out s_uId);
Int32.TryParse(s_uId, out uId);
