I'm using .NET 3.5 and I have a class, A, marked as internal sealed partial and it derives from System.Configuration.ApplicationSettingsBase. I then use an instance of this class in the following manner:
A A_Instance = new A();
A_Instance.Default.Save();
Why would the Visual C# compiler be complaining:
error CS0117: 'A' does not contain a definition for 'Default'
?
