Re: [Mono-dev] bug #28777

[Rodrigo Kumpera]

No timeline for 4.0.5. It might be a community only release.
Mono 4.2.0 has already been branched and an alpha release is happening in
the coming weeks.

Re: [Mono-dev] Invoking .net interface method from c api

Oh. I got your point.

The build output have System.dll in multiple places.

./lib/mono/2.0/System.dll
./lib/mono/4.5/System.dll
*./lib/mono/gac/System/4.0.0.0__b77a5c561934e089/System.dll*
./lib/mono/4.0/System.dll

I was loading it from ./lib/mono/4.0/System.dll. I am loading it as follows.

mono_set_dirs("/lib", "/etc");
pDomain = mono_jit_init_version("BuildDomain", "v4.0.30319" ); // Init 
the
JIT Engine
mono_config_parse(NULL);

MonoAssembly* pSystemAssembly = mono_domain_assembly_open (pDomain, 
"/lib/mono/4.0/System.dll");
pSystemImage = mono_assembly_get_image (pSystemAssembly);

The file in gac seems to have the implementation.
How to make it load from gac without providing absolute path? Please note
that I cannot install it here.



Use one of the mono_assembly_load_*() functions because they
are obeying the usual CLR assembly binding rules (those rules C#
programmers are used to).


A good start is mono_assembly_load_with_partial_name () which
can be as simple as:

MonoImageOpenStatus status;
asm = mono_assembly_load_with_partial_name("System", &status);

So I opened mono/4.0/System.dll using ILSpy. There, all the methods seems to
have empty body with single instruction.


What could be the issue ?



It looks like you are tying to execute a reference assembly.
These are stripped off of method bodies.

How do you load System.dll?
