writing data in config file

Hello,
I am using config file in C# form application. I have provided UI which takes the data form user and on request saves the data to the "Properties.Settings.Default.MyVal"

The problem is that internally(while debugging the application i saw) it knows that the particular data has been modified and reads the modified data but these changes are not reflected in app.config file.

How should i save the data to the "Properties.Settings.Default.MyVal file" so that it reflects to the app.config file exacly.

Thanks.
