dotnet general: Use this overload of the ApplicationException constructor

ApplicationException(string, Exception

hello all,
we are writing a class lib dll and want to use our own new app exception.

we want them to have the same 'Message' and "InnerException' members as all
Exceptions have.

we cant override these members because they are 'read only'....

any suggestions ?
what do you do ??

thanks, Ran.
