Default AppDomain

[siger99]

Hi,

I try to use a 3rd party assembly ( basically a layer of managed C++
around a native C++ lib).
Unfortunately, it was developped for NET 1.1 and knows only the
default AppDomain.

When I try to call it from another AppDomain, I get the "Cannot pass a
GCHandle across AppDomains" error.

-> is there a way to get the Default AppDomain from the Current
AppDomain?
-> has anybody found a way round this "GCHandle..." error ?

Thanks in advance

This isn't an error, you are simply doing something that you can not do.
You are not allowed to pass GCHandle instances across app domains, and that
is exactly what you are trying to do.

What exactly are you trying to do here? Why are you passing a GCHandle
across app domains?

Hi,

Sorry for the late reply.

I am in a user-defined AppDomain (because I want to be able to unload
the assembly when I am done with it), and from this AppDomain, I call
the
3rd party assembly which expects the defalut AppDomain, hence the
crash.

So I have to figure out how to launch this 3rd party from the default
AppDomain to make it work.

Any idea?

Thanks again
