Compression of .net executables

Hello

I've developed a DotNet application and I'm looking for software that can make my application smaller with no luck, I've used UPX but it doesn't compress my exe file.

I've found netshrink exe packer, it looks good, but I'm beginner programmer, could anyone test it and tell me what do you think about it, is this a good application for my needs?

It can be downloaded from www.pelock.com/products/netshrink official site.

thanks Smile
