Amazon web services working examples

Question

I have searched high and low to try and get the Product Advertising API to work - I have tried many examples from these forums and from the internet and it does not work. There has been some talk about modifying the WSDL and that does not work either.

Here is where I have been:
https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html
http://aws.amazon.com/code/Product-Advertising-API/3941
http://aws.amazon.com/code/Product-Advertising-API/2609
http://flyingpies.wordpress.com/2009/08/13/signing-amazon-product-advertising-api-cwcf-part-2/ *

*This was the best tutorial until AWS changed the WSDL with NO examples on how to deploy - I am actually starting to wonder if they even test their stuff before release!

Can anyone PLEASE point me to a working C# example?

EDIT
I am also aware of the information posted at
https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html
meaning that I am aware that the AssociateTag must now be included with every search etc.

Answer 1

I had a similar issue recently, I used the last link mentioned above to create a c# application but since the new realease this stopped working and i couldn't fix it.

I downloaded this example:

http://aws.amazon.com/code/Product-Advertising-API/2481

And made some small changes and got it all working...

The main one changing the namespace to:

http://webservices.amazon.com/AWSECommerceService/2011-08-01

Throughout all the code......

I think I may have updated the code in a couple of other places and can help you if these errors occur
