WCF consumed as WebService adds a boolean parameter?
- by Martín Marconcini
I've created the default WCF Service in VS2008. It's called "Service1"
public class Service1 : IService1
{
public string GetData( int value )
{
return string.Format("You entered: {0}", value);
}
public CompositeType GetDataUsingDataContract( CompositeType composite )
{
if ( composite.BoolValue )
{
composite.StringValue += "Suffix";
}
return composite;
}
}
It works fine, the interface is IService1:
[ServiceContract]
public interface IService1
{
[OperationContract]
string GetData( int value );
[OperationContract]
CompositeType GetDataUsingDataContract( CompositeType composite );
// TODO: Add your service operations here
}
This is all by default; Visual Studio 2008 created all this.
I then created a simple Winforms app to "test" this. I added the Service Reference to my the above mentioned service and it all works. I can instanciate and call myservice1.GetData(100); and I get the result.
But I was told that this service will have to be consumed by a Winforms .NET 2.0 app via Web Services, so I proceeded to add the reference to a new Winforms .NET 2.0 application created from scratch (only one winform called form1). This time, when adding the "web reference", it added the typical "localhost" one belonging to webservices; the wizard saw the WCF Service (running on background) and added it.
When I tried to consume this, I found out that the GetData(int) method, was now GetData(int, bool).
Here's the code
private void button1_Click( object sender, EventArgs e )
{
localhost.Service1 s1 = new WindowsFormsApplication2.localhost.Service1();
Console.WriteLine(s1.GetData(100, false));
}
Notice the false in the GetData call?
I don't know what that parameter is or where did that come from, it is called "bool valueSpecified".
Does anybody know where this is coming from? Anything else I should do to consume a WCF Service as a WebService from .NET 2.0? (winforms).
