How To: Split Web.Config Sections To Multiple Files

Why Split Web.config Sections to multiple files :

1- Easy to maintain.
2- Organizing the Work.
3- Avoid The Error " Cannot read configuration file because it exceeds the maximum file size "

Let's begin:

- We will Split the following sections to separated files:
1- AppSettings.
2- ConnectionStrings.
3- SafeControls.
4- Bindings.
5- Client.

In every section you would like to split you should follow the following steps :

1- In Web.Config Section Cute the entire section contents.
2- Create New File and name it as you want but end with .config E.g. "appsettings.config"
3- Paste the section contents inside the file you just created plus the section tag it self
