Yes, there is a
bit of confusion about this (also read
this post).
I understand that the right way to create your application specific exceptions classes is to inherit from Exception class:
public class MyCustomEx : System.Exception{
//class implementation
}And if in any case you have to throw a general application exception that has not specific type, throw a System.ApplicationException:
throw new System.ApplicationException("Error retrieving data. The web service may be down");
