Description of Problem:
If you try to access settings from App.config using the
System.Configuration.ApplicationSettingsBase model, or in other words, the code
created using the Visual Studio settings code generatation, a null exception
will be thrown if more than one section exists under applicationSettings.  



Steps to reproduce the problem:
1. Create a new console project in VS.
2. Create two new settings files and add a setting to each.
3. In code, try to write the two settings to the console.
4. The exception will be thrown.
5. To get the correct behavior (from the first setting file only), comment out
the second setting's section in applicationSettings in App.Config. 

Actual Results:
The exception below will be thrown.

Expected Results:
The setting value should be returned.


How often does this happen? 
Every time.
