How to Re-Sign (Strongly Name) an existing .NET Binary

Do you have an existing .Net binary you are trying to use with an existing project that uses strongly named binaries?  If the pre-existing binary is not strongly signed too, you can't use it.  Doh!  I found this nice tutorial that shows you how to de-compile and existing binary and re-sign it with a new key!
