In this article I will discuss how to create a code snippet. Visual Studio allows developers to save snippets of code which can be inserted at a later time. This saves on retyping blocks of code that are used often. I also find it very useful when I have to show code during presentations. Instead of typing everything live, I find it far easier to simply add the code block by block using code snippets.

Fallow the steps to create a code snippet using Visual Studio 2010.
