FIX: GetValue function is called multiple times on each DataBinding event in Windows Embedded Compact 7

Symptoms
Assume that you have a Microsoft Silverlight for Windows Embedded (SWE) application that runs on a Windows Embedded Compact 7-based device. The GetValue function is called multiple times on each DataBinding or PropertyChanged event. This issue could lead to a performance issue on the application.
Resolution

Download information

The Windows Embedded Compact 7 Monthly Update (July 2015) is now available from Microsoft. To download this Windows Embedded Compact 7 monthly update, see Windows Embedded Compact 7 updates in the Microsoft Download Center website.

The kind of processor that each file applies to is visible in the name of each file in the "File information" section.

Workaround

For the same binding property name, on each DataBinding event, add a cache in order to save the last property name, then at the second time, system will not call GetValue until the third time.
