How can I determine if the application config file exits?

You can determine if your application configuration file exists by checking the value of the Application Settings Manger's static ConfigFileExists property.

For example, in C#:

using OakLeaf.MM.Main.Managers;

...

if (mmAppSettingsManager.ConfigFileExists)
{
	// Code to be executed.
}

In VB .NET:

Imports OakLeaf.MM.Main.Managers

...

If mmAppSettingsManager.ConfigFileExists Then
	' Code to be executed.
End If
