Is there a design...

I'm looking for a way to emulate virus-like behaviour for testing exclusions in anti-virus software. Can anyone recommend some behaviour that I can put together in a quick script which would trigger a typical realtime anti-virus scanner?

If the base class actually implements some behaviour then I think it's called a non -abstract base.

In WCF, what is the difference between a Behaviour and a Contract ? From examining the config file, both seem to point to the interface of the service functionality. Why are they both needed?

The Contract is the interface -- it defines the service operations exposed by the WCF service, which may or may not correspond 1:1 to an unadorned code interface your application .

Many of our system tests are written in a BDD style, and we make decent use of inherited behaviours to minimise duplication, for example this might be a basic hierarchy for purchase tests.

Expanding on PoweRoy's answer.
I don't know how you use the DateTimePicker but what about using a simple editbox? (and validate date when a date is entered)
DateTimePicker is mostly used to choose a date without entering any number .

The UI classes shouldn't contain logic - only the code needed to display the interface .
