How to create a WSDL from a C# method?

Question

I have a C# application, and now I need to create a web service from a method that already exist in a windows form app.

Whats the best way to do this ?

Can I generate a wsdl file just for the file or methods that I want to expose ? And then, how can I put it in the IIS, my application is client-server, so, it isn´t in the IIS yet.

Thanks

If you have code that you have multiple applications accessing, I would split them off into their own dlls and reference it in each application that needs access to it. This is easier to manage.

Create a WCF Service Application Project. This will create the structure needed to host the service via IIS.

IService1 will be your interface. You will create a OperationContract here

[OperationContract]
string HelloWorld();

In Service1.svc you will add code that you will access your dll

public string HelloWorld()
{
    return MyClassFromDll.HelloWorld();
}

In your project that will access the service you will add a service reference pointing to the IIS server hosting your service. This will automatically add the needed code to your project.
