This is a multipart series on how to share code between .Net platforms.  All the examples will be showing how to share between Windows 8 Store applications and Windows Phone 8 application, but the techniques are useful for sharing code between any .Net/Xamarin platforms.

What is Inheritance?

I’m just going to go ahead and assume you understand inheritance, but I’m keeping this section to stay with the theme from the other posts in this series.

What are Partial Classes?

Partial Classes are a way to split a class up into multiple files. It is frequently used when one part of your class is generated code and another part is written by hand.  In this case we’ll use partial classes to separate code that is shared between platforms and code that is platform specific.

What is Conditional Compilation?

Conditional Compilation tells the compiler to selectively compile code.  Many developers use these to run certain code only while in debug that they don’t want to run in production.

 What are Linked Files?

Linked files are a way for two or more projects to both reference the same file.  One project generally keeps that file under it’s file structure, other projects reference the file there.  You can open the file from any of the projects as you normally would and edit it.  All changes are saved to the one file.

I just answered this question on StackOverflow about how to generically compare an inserted row to a deleted row within a trigger. I started by just commenting that it would be a good place to do a little code generation, but something about the problem wouldn’t let me put it down. Here’s what I came up with.
