What I meant by
"I can use a conditional compile and use a simple delegate in CF"
is that the classes that use WeakMulticastDelegate in our framework
could use a simple delegate in CF with a conditional compile and I
would exclude this class from the CF solution.

So how does .NET 2.0 CF deals with delegate targets ? Do they prevent
objects from being garbage collected ?
Of course I can use a conditional compile and use a simple delegate in
CF, but if delegate still keep a strong reference to their target,
then I would need to find a way around that.
