Is there an up-to-date c# sample for the Amazon product API?

So, I finally found the solution, based on a comment posted here: http://www.falconwebtech.com/post/2010/06/14/Using-WCF-and-SOAP-to-Send-Amazon-Product-Advertising-API-Signed-Requests.aspx This is also the URL, where I downloaded the code I made working.

I didn't pass my "Your unique Associates ID", which I didn't even had until just now. You can get it here: https://affiliate-program.amazon.com/

Add

itemSearch.AssociateTag = "YourAssociateID";

before amazonClient.ItemSearch(itemSearch).

Works like a charm

I have found a up-to-date project, the code is available on github Nager.AmazonProductAdvertising

nuget

PM> install-package Nager.AmazonProductAdvertising

Example

var authentication = new AmazonAuthentication("accesskey", "secretkey");
var client = new AmazonProductAdvertisingClient(authentication, AmazonEndpoint.US, "YourAssociateID");
var result = await client.GetItemsAsync("B0037X9N5U");
