Hi Peter,
That preprocessing statement was added during the 0.91 release phase, when
NAnt was still using the .NET 1.0 runtime by default.  We were having
issues between .NET 1.0 and 4.0, which is why that statement is there.  I
just took a look at the .NET docs and the AppDomain.CreateDomain method you
mentioned was actually created in .NET 2.0 (my fault for thinking it was
added in .NET 4.0).  Based on my findings and the fact that we are now
building NAnt/NAntContrib on .NET 2.0 runtime (as of 0.92 Alpha1), we can
just eliminate that preprocessing statement altogether and just use the
AppDomain.CreateDomain method with the PermissionSet as standard without
issues.  It'll need testing, of course.

Would you mind adding this to our issues list for tracking purposes?  I'll
see if I can get to this within the next couple of days.

Thanks,
Ryan
