Let's Watch a Movie...
Here's a nice movie to watch for setting up VS to work with the command line to generate some code for you:

Using the Command Line Tool for Non-Web Apps
This is a walkthrough of how to setup Visual Studio to call our command-line tool, sonic.exe.
Configuration
SubCommander will always try and find a configuration file in its executing directory (Web.Config or App.Config). If it does, it will look for config information for itself there, and set itself up accordingly. You can override this by using the /config switch, and then telling it where it can find the config file:
sonic.exe generate /config "c:\myproject\App.config"
If you're working with a project and you want to use our generated code, just add an App.config file to the project, then you can run SubCommander in that directory.
Manual Configuration
All of the config options can be passed in as switches ("/includeTableList table1, table2, table4" e.g.) to SubCommander. This is handy for when you want to use a BAT file.
Scripting Schema and Data
You can script out your schema and data (and then version it in your favorite source control system) using SubCommander. Simply use the command "version" and tell SubCommander where to put the data:
sonic.exe version /out Scripts
This will output a script file (.sql) to the local scripts directory of your project
