custom Exception class

[Tony Johansson]

Hi!

I just wonder if I will create an custom exception class which of these two
alternatives is it best to use.

public class TeamListFilledException : ApplicationException
or
public class TeamListFilledException : Exception

MS's point of view in docs is:

<quote>
For most applications, derive custom exceptions from the Exception
class. It was originally thought that custom exceptions should derive
from the ApplicationException class; however in practice this has not
been found to add significant value.

So once upon a time MS preferred the first, but today they prefer the
last.

So I suggest that you go for the last!
