Visual Studio code snippets for creating fast and easy data sources

If you have to reuse the same code over and over again in different projects, the Visual Studio provides a nice feature for this - "IntelliSense Code Snippets".
For example, as you all know, you can create a constructor for a class by typing "ctor" inside that class 

 This is a pretty simple code snippet, but you can expand it and create more complex ones and reuse this code within few key strokes.

How to make them :

1. Add a new File in the Visual Studio :

2. Choose an XML File and save it as a .snippet file

4. Fill the minimum required fields for a code snippet

5. Build on and create your own code snippet

How to install them :

All you need to do is copy then to your Visual Studio Code Snippets folder.It should look like this :

or :
<drive>:\Program Files (x86)\Microsoft Visual Studio X.0\VC#\Snippets\1033\Visual C#
