Entity Parser for MVC and S#arp Architecture

Sprache: C#

Diese Controller Erweiterung liefert anhand einer per Request übergebenen ID eine S#arp Architecture Entity zurück. Die Entity wird nur dann neu gefetcht wenn die neue ID und die aktuelle ID nicht übereinstimmen. http://code.google.com/p/sharp-architecture/
