By using Java? :)

Seriously, checked exceptions a la Java were such a bad idea that even
Java people came up with "patterns" to convert them to unchecked
exceptions. C# designers simply discarded checked exceptions from a
start and designed their exception handling based on the Python
exception handling model. (This is mentioned in a Microsoft's paper,
but I don't have the reference off hand.)

So, no need to mix exceptions with interfaces, unless you are a
masochist.
