While at MIX10, I met up with Robert Kihm, Director of Product Architecture at Aptify. We talked about how Aptify enables you to create metadata for an application as well as surface the UI, including bindings and validation rules across multiple user interfaces (Silverlight and Windows Forms shown), without making any changes.  Building on all the cool things in .NET, Aptify uses Silverlight, WCF RIA Services, SQL Server, Regular WCF SOAP Services, and tons more to help you build cross-technology, cross-platform business applications using Microsoft tools and technologies. The Aptify Web Site offers more details on the Aptify product. Visit Pete Brown’s Blog at 10rem.net for more information on Silverlight, WPF, Windows Phone, C++, and more.
