Moving MSMQ applications from 32-bit to 64-bit archirtecture

Migrating MSMQ applications from 32-bit to 64-bit systems shouldn’t be a big deal. In theory you will probably be able to just recompile / redeploy as the public MSMQ APIs are not architecture-dependent. Other parts of your own code may be, though, so make sure you check the Getting Ready for 64-bit Windows MSDN article to…
