While in Irvine, CA on the .NET Rocks! Visual Studio 2012 Launch Road Trip, Carl and Richard talked to Paul Sheriff about architecture in a heterogeneous world. The conversation starts out digging into Paul’s long history of building software that can stand the test of time – being able to tolerate changes and add new features without having to do the ‘big rewrite.’ Paul discusses the various patterns of architecture that can handle a diversity of clients as well as the realities of unreliable connectivity and distribution.
