Hello: I have a winows application that I'm currently creating a web service to connect to the backend. The back end was access but I have migrated it to sql server.

I noticed that if you want to place the database in the App_data folder, you must use the express edition of sql and so I'm trying to figure out if it's better to use the express version primarily for the purpose of having the database in the App_data folder. What are the primary benefits of placing in this folder verses having it located else where?

Thanks,
Proctor
