I am pretty sure this can be done as Visual Studio 2005 already tells

I'm not aware of any feature in VS that does this generally.  It's true  
that the documentation for much of .NET includes information as to which  
exceptions may be thrown, and inasmuch as VS shows you that documentation,  
it will show you those specific exceptions.

If you know of something more specific than that, perhaps you could  
provide more details regarding what you're seeing in VS.

Also Red-Gate Exception hunter validates your code and highlights all
possible exceptions (part from generic exception).

I'm not familiar with that tool.  However, it's plainly false that it  
"highlights all possible exceptions".  No doubt it does a good job  
traversing the call chain (something that's easily done via reflection),  
looking for code that creates and throws exceptions.  But it's simply not  
possible to find literally all possible exceptions.

As Marc already asked, was there some specific situation or scenario  
you're trying to address?  Generally speaking, if it's possible for a  
method to throw some exception that can be usefully dealt with, it will be  
documented by the author of that method.  Other kinds of exceptions that  
might be thrown wouldn't be relevant information anyway, by definition.

Hi

This is possible and it's standard in VS Studio 2005 (C#).

Hover your mouse over a method (e.g. System.IO.File.Open) and wait for
the little popup window, here lists all known exceptions (again part
from generic exceptions), so it is possible.
