Most of the time I'm getting a single .exe when I create a package. However for several of our databases I get several files when I try to package:
The .exe file is small but all the .dll files can be very large (i'm guessing this is the data). The other issue is that the package creation is MUCH slower when it runs when this happens compared to a single .exe file. I believe database size is a factor since several of our databases can be fairly large -- 200+ megs.
I am running SQL Packager 22.214.171.124 which is the latest current version but I experienced this in the last version as well.
