Commission Junction recently announced a new version of their Web Services, which now supports Microsoft .NET.

New Web Services page

WSDL List (Current version 1.1)
http://api.cj.com/

They include some rough documentation on how to utilize the code for a Windows Application (C# or VB.NET) using Visual Studio 2005.

Here is a very quick overview of how to utilize it with a Web Application using Visual Studio 2003.  This demonstrates using their Product Search method used to grab product data from merchants.

1) Start a new VB.NET Application or Web Application
2) Add a new Web Reference
Enter http://api.cj.com/wsdl/rpc_encoded/productSearchService.wsdl
And Hit Go
3) Name it CJProductSearch (or whatever you want)
4) Copy the performProductSearch function included in the sample code package to your Webform1.aspx.vb.
5) Change the Console.WriteLine entries to Response.Write
6) Fill in any test data.
7) Make a call to the performProductSearch from the Page_Load

That’s it.
