AmazonECS.Net is an open source .net library developped in C# for the
Amazon E-Commerce Service. It can be used in any .Net application by
any developer who wants to use Amazon's ECS. Built using a simple and
clean design, it is very easy to use and implement.

The library can be used in many ways, from a simple item listing in an
application or website to a complete high-level ecommerce website
including remote shopping cart management. AmazonECS.Net makes it
simple to earn money using your Amazon Associates account. It also
features a caching engine for all requests to make response times
smoother and faster.

Most libraries available for Amazon's ECS are in PHP. AmazonECS.Net is
one of the firsts (if not the first) made publicly available for the
..Net platform.

The library currently supports the following features:

* Access Amazon.com product data (only the US locale is supported)
* Request Validation
* Caching engine
* Search and browse Amazon
* Navigate categories
* Get detailed item informations
* Get latest releases
* Get top sellers
* Manage a remote shopping cart
