Re: GCHandle exception (appdomain related?) (was: Re: [Partly-SOLVED!] Re: Output from Console.WriteLine methods is deferred)

Hi Andres, 

The documentation for domain= is buried on this page:
http://nunit.org/?p=consoleCommandLine&r=2.4.7

I've recently had several questions about domain=None,
leading me to realize that something like the following 
should be in the docs.

Domain=none is a hack that most people should never
use. It was created for one user, with code that could
not even execute correctly in a secondary AppDomain.
Since there is only one domain, there is only one 
application base and config file. To use it, you must
copy the NUnit itself to the directory containing your
test assembly. Any entries you would normally put in
a test config file must go in the nunit config.

Unfortunately, because there is no such text, lots of 
people try it as soon as they have a problem with
AppDomains. Our bad.

Do you have any indication of where the exception
is being thrown?

Charlie
