Description

In this episode of Defrag Tools, Andrew Richards and Chad Beeder walk you through a common issue in Windows Store applications that use Frame.GetNavigationState. We use a Windows Store 8.1 app sample to show how using complex objects as a parameter in navigation can cause serialization to raise an exception.
