[Solved] Deployed a 3-Tier ASP.NET website and lost the app.config for my Data Layer! How do I get the connection string out of it?

My solution explorer looks like this (proprietary bits redacted):

OK. So I used a .xsd file which I generated by

1. Clicking to add a new Class Library project called DAL to the Solution and then clicking the Data menu, and then clicking Add New Data Source and going through the whole wizard whatever...

2. I answered yes, save the connection string when the wizard prompted me.

3. The app.config under my __DAL project contains my db connection string

It's a usual 3-tier jazz, and it works fine when I press F5 or CTRL+F5 in the Visual Studio (2010, by the way) and then when I click the Website, click the Build menu, and then click Publish, I get the box

Is there something I am setting wrong? Only the web.config file gets published but not the DAL's app.config. Then, when I go to deploy the website and do a test run I get the screen

Then when I publish, there's no ___DAL.dll.config file in the \bin subfolder, just the __DAL.dll. Can someone please help me figure out how I would go about setting things up correctly? I'm a bit of a newbie.

Thanks!
