[Mono-dev] Mono 3.0.10: channel type IRequestSessionChannel is not supported.

[Pierre Gronlier]

Hi,

I made this change in mono-3.0.12 (the files haven't change since
3.0.10 when I tried and the callstack is the same) but it is evaluated
as false.
Even if I force the condition to be true, the cast is failing.
TChannel is of type IRequestSessionChannel.
How could it cast a IRequestChannel instance object to a
IRequestSessionChannel object since IRequestSessionChannel inherits
from IRequestChannel? (I would understand the other way around but not
this one.)
