Re: MEC++ - propogating FullTrust to another AppDomain with a different application base

I've not done anything with stored policy on my system. As for AppDomain
policy, all that I have done is use the 3 argument CreateDomain method. For
the evidence argument I just pass the evidence of the current domain (which
is the default domain). Should I pass something different? Can I pass
null? I didn't really know what to pass for evidence, but I needed the 3
arg constructor because I needed to pass the AppDomainSetup for the
different application base and app.config file. Is it because the
application-base is different than the current app domain that the trust
level is downgraded?

I think that I could probably produce a boiled down example that
demonstrates what I am seeing. Anyway, do you have any other ideas for me?
