How to use Prefix.pch in WP8 like in iOS?

Question

In iOS I have 5 application which use same code. I was able to refer the common classes and separate the application name, theme and color using the values from the Prefix.pch f

Answer 1

C# language supports defines which can be defined either globally in the project file or you can define them on top of any file:

#define USE_BROWN_THEME

However, using application name is set in the WMAppManifest.xml file and you can only check/read it at runtime, you cannot do that at compile time. And xml files don't play well with #defines.

#define (C# Reference)
