Hi prashantlakhlani,
We can use Visual Studio Item Templates for this request.
Create a CS file in your project and change the content you like. Then select File | Export Templates menu. You can export the CS file as a template. It will appear in My Templates section of Add New Item dialog.
For more information, please access following link:
