I like to keep our applications Strong Named for a multitude of reason which can make finding third party assembly's a pain.  As simple as strong naming is many vendors are to lazy or ignorant to sign the assembly.  Friday I left the office with some unsigned enterprise library DLLs, being lazy I didn't want to recompiling them my strong name signature.  Thankfully I found a nifty little app by Alois Kraus that will add a strong names to unsigned assemblies.  I also happened upon a tool for removing a strong name from codeproject.  Not sure when it would be of use.
