It's not all that unreasonable to say &quot;you must take care in handling
the intptrs so that you don't call into another AD&quot;.
Anyways, we should see what msft has to say about this. Can you post
the bug reference on msdn.

+
+It can't be the expected result to execute instance methods in a
+different AppDomain than they belong to. There are two resonable
+solutions: disallow cross AppDomain delegate marshaling or execute
+methods in the right AppDomain. The current behaviour is a nonsense.
+
+&gt;&quot;fixing&quot; this bug wouldn't make us run real life programs any
+&gt;better.
+
+I think that delegate marshaling is a real life scenario. Unmanaged
+code is portable at source code level and there are situations when
+it is needed. And when you pass marshaled delegates to unmanaged
+code that code can pass back marshaled delegates to managed code
+even that are in different AppDomain.
+
+&gt;It's not all that unreasonable to say &quot;you must take care in
+&gt;handling the intptrs so that you don't call into another AD&quot;.
+
+As you get and IntPtr to an unmanaged funtion it's the runtimes
+responsibility to take care of AppDomain as you cannot.
