Obfuscator/Packer identification

[amri_amin]

Hi,

I have a .Net assembly packed into win32 executable. I've tried many tutos to extract the .net code without success. Is there any method (footprints, tools ...) to identify the obfuscator used.
Thanks

maybe it's a better idea to post the target so that people can have a look at the file.
