[Mono-dev] modified classes compile but don't find method on running

[Iván Herrero]

Hi. I've been hacking the sources to provide support to reference the element 
to sign in a xml doc with an xpath expression. For that, I've modified the 
Reference.cs and SignedXml.cs classes. When I recompile the code of mono and 
make install it, the new method doesn't appear in monodevelop. However, I've 
managed to compile it from the command line, but when I run the test code 
that use the new method, this is not found, and it crashes:

	navitux at darkness:~/Projects/firmado/firmado$ 			 
	mcs -r:System.Security -r:Mono.Security -r:System.Xml Main.cs
	Compilation succeeded - 6 warning(s)

	navitux at darkness:~/Projects/firmado/firmado$ ./Main.exe
	 ** (./Main.exe:25186): WARNING **: Missing member SetXPathReference in type 	
Reference, 
assembly /usr/lib/mono/gac/System.Security/1.0.5000.0__b03f5f7f11d50a3a/System.Security.dll

	Unhandled Exception: System.MissingMethodException: Method not 	
found: 'System.Security.Cryptography.Xml.Reference.SetXPathReference'.
	in <0x00000> <unknown method>
	in <0x00039> firmado.MainClass:Main (System.String[] args)

I'm quite surprised with the error, searching the library in 
gac/System.Security/1.0.500..., which seems not to be in the standard library 
tree. Added to that, depending on the compiler used (mcs, gmcs), the library 
used is in 1.0.500000... or 2.0.0.0__b03f5f7f11d50a3a folder.

Could you put some light into this so I can test and improve these hacks?
Thanks,
Iván.
