So I have been working intensely with Subsonic lately and I need to change the database back end. Add a table and delete some columns. Oh boy!
It is very simple just delete the .abp file and create a new one. Now rebuild the web project and enjoy the updated objects.
**Update**
according to Rob Conery(the guru of subsonic):
"It's easier than that even :). Just "tweak" (add a space, and save) the abp file to update it's Last Modified and you're all set!"
How true it is. Thank you Rob for the update. Subsonic makes my life sooo much easier.
