+The reason this fails on Mono is because System.IntPtr doesn't define
+any conversions from or to ulong -- there is no IntPtr(ulong)
+constructor, for example.
+
+A workaround is to introduce a cast:
+
+    ulong value = ...;
+    IntPtr p = (IntPtr) (long) value;
+
+You could also use (void*) as the intermediate cast.
+
+I would like to know why this works with CSC.EXE, as msdn2 doesn't
+list any IntPtr members that work with the UInt64, so either CSC.EXE
+has an internally-permitted conversion from ulong, or their class
+library has some members which aren't documented.
