Question : Sending and Receiving Data like a Dataset using WCF between two or more programs over internet without IIS Configurations

Hello all,

I need to run a program on a computer server that listens a specific port and send/receive data over the Internet without IIS, because I do not want that the end user needs of having to configure anything other than a free port in your firewall. On the other hand, the client side, I need that the program send/receive a Dataset with the server program with all kind of data, like images, texts, movies or pdf files. I'm trying to use WCF with a winforms application. Can anyone give me an example of how to do this?

Thanks in advance.

Ok. This is a *very* basic example. You basically create a ServiceHost object to host your service. Give it an endpoint (mine is just running locally). You also want to define a behavior object so you can enable the Mex, if you so choose. Once you have your service defined, you can run it. Navigate to the endpoint you setup in a browser and you should get the "You have created a service" welcome page. You can copy the line similar to

svcutil.exe http://localhost:10000/?wsdl

and then open up the Visual Studio Command Prompt. Paste the line into the command window and execute it. It should generate two files--a class file, which is basically your proxy to the service, and a config file. Add both files to your client project/application. Rename "output.config" to "app.config" or add the contents of "ouput.config" to your "app.config" if it already exists. Once you have done that, you should be able to create a "proxy" object and call the method you defined in your service/interface. See below.
