Unused functions in fusion.dll

[Francois Gouget]

The following fusion.dll functions are unused: nobody calls them and 
they are not exported.

CompareAssemblyIdentity()
  GetAssemblyIdentityFromFile()

I checked a Windows fusion.dll I have here and I did not see them being 
exported there either. Yet, the MSDN documents them and presumably 
there's a way a application can call them...

Does anyone know what's up?

What version of the .NET framework do you have? It looks like these came 
with 2.0

Forget that remark. Just checked both fusion and mscoree on .NET 1.1 and 
3.5 and neither have these exports.

So, no clue ;)

Those functions are exported normally from the implementation mscorwks.dll 
(but noone guarantees that) and no executable or DLL is linked directly to 
it, instead they call GetRealProcAddress in mscoree.dll

Forgot to add that on Windows Server mscorsrv.dll is loaded instead of 
mscorwks.

No idea why m$ created two implementations for those functions and classes, 
one for workstation and one for server. Could be a $$$ issue?

/me wonders if there's a mscor3apps.dll for windows starter edition.

I have vague recollection it's to do with threading models and somesuch.

I came across a discussion of it while doing XNA stuff, which is
actually compact framework so different again. ^_^
