Hi Shailesh,
Did you use the Ngen tool with ICSharpCode.SharpZipLib.DLL to create a
native image?
Native Image Generator (Ngen.exe)
http://msdn.microsoft.com/library/de...us/cptools/htm
l/cpgrfnativeimagegeneratorngenexe.asp
If so I think you may use the assembly name as the argument of Ngen.
I think you may try to workaround the problem by using any of the three
workaround.
1. You could use the full assembly name.
2. You could change into the directory where the assembly lives and then
pass in the partial assembly name.
3. You could just use filenames instead of assembly names. For instance,
you could provide the full or partial path to ngen, or just change to the
directory where ICSharpCode.SharpZipLib.DLL lives before you compile it.
For detailed information you may try to refer the link above.
Did I misunderstand you meaning?
If you have any concern on this issue,please post here.

Peter Huang
