Hello Robert,

thank you for your answer!

Actually, my pre-compilation code bases on the Full-AOT
code of Mono 2.6.1. Particularly, it uses code of
'collect_methods()' and 'add_wrappers()'. Instead
of calling 'add_method()' in order to add a chosen
method to the AOT-compile structure, my pre-compilation
code calls 'mono_compile_method()' in order to pre-compile
the method. Quite simple. However, the signature sharing
seems to work not properly for my purposes. In
'mono_marshal_get_runtime_invoke()' the 'runtime_invoke_cache'
returns one wrapper for different call signature, e.g.,
for 'System.Threading.WaitHandle:set_Handle()' and

As far as I see, the code of 'add_wrappers()' and
'mono_marshal_get_runtime_invoke() 'is nearly
the same in Mono 2.8.2 (which supports Full-AOT for
x86) and it seems to work there. Does the signature
comparison function have changed since Mono 2.6.1?

With kind regards,
Martin Däumler
