Method to build patches using MSI

I work i开发者_如何学编程n an application built upon Visual Studio 2010 and often make little fixes.

I need a method to send these fixes like a patch, a MSP file I guess, not the complete MSI file. How can I do this?? Is there an article or a link?

Patch is a difference between two MSIs. So to create a patch, you would need the original MSI package and the updated one.

Read the following articles in the MSDN:

• Patching and Upgrades
• Patching
• Creating a Patch Package

I also have a step-by-step instruction on how to create patches using WiX Toolset.
