I can highly recommend the whole Magento CMS which comes equip with a robust shopping cart and advanced functionality to link with your inventory and accounting software.  On top of this it's SEO friendly, open source and allows you to easily up sell and cross sell, leading to high basket size and corporate profits.

I have used Magento in the past is is a good system with good SEO capability, you may need to tweak it for speed some times. But as you are requesting a ASP .net solutions are usually not the best I have heard some decent comments about Umbraco, an open source solution yet have not tested it personally.

Hope this helps

Magento all the way. We have grown upto 250% after giving Magento related services this year.

Another popular solution to investigate would be Drupal CMS running Ubercart
