Greeting Rick,

That's what the connection string looks like. The exception error says "A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."

Regarding these possibilities:
1) I know it exists - isn't the B.O.G. going to use it to generate objects?
2) The Server Explorer is showing the database info, would this preclude the B.O.G. from accessing the file?
3) The file is on my c drive.

Thanks for your help.

Regards,

E.R.

>>Thanks for the info Rick. Right now I'm just trying to get the Mere Mortals Business Object Generator to see my database in the app_data folder. I'm getting an exception in the Business Object Generator wizard when I put in the connection string that's in my web.config. The format of the connection string is different when you're just using an .mdf file rather than a regular database and I'm guessing that MM doesn't know how to use that type of connection.
