WCF Calling C# Methods

I used to code only in databases enviroments. Recent changes in the corp. made me start developing in whole new worlds. This new project is something like SQL - C# - PHP.

The class I've been working on in VS2008 is almost dnoe. It calls all the SQL SPs I need and the info is there in the DataReaders. When It came to read that info from PHP so I could populate the website I found out it wasn't that easy. I was recommended into trying several options, the one that suits the best for the project is to create a Web Service and then consume it (please be patient, As I just stated I'm new to most web related programming) So, I'm trying to WCF/Rest and then consume it from PHP but I haven't got there yet.

I've read and watched several tutorials on WCF and It seems to be smooth, but all I've read is:

. Create Interface with its OperationContracts.

. Create Service with DataMembers etc and define the Methods listed in the Interface.

Ok, but what I'd like to do is not to specify any methods there, since all I want is to call C# method I've already written. Should I do that in the Service or in the Interface? And first of all, is this the right the way to approach it?

You would want to write service methods that implement an operation contract interface. The service methods can call the C# code that you've already written.

For example, here is a simple service interface:

[ServiceContract]
public interface IYourService
{
    [OperationContract]
    int GetCountOfTransactions(string filter);
}

And then you would implement this interface in your service class:

public class YourService : IYourService
{
    public int GetCountOfTransactions(string filter)
    {
        // Call your existing code
        YourClass yourClass = new YourClass();
        return yourClass.GetCountOfTransactions(filter);
    }
}

There are plenty of examples out there for setting this up as a REST service, but I think you're on the right track.

The trickiest part is usually setting up the binding configuration to make sure all of your consuming client applications can connect.

Hopefully this helps.
