Billy Bob,

Unless you explicitly ask Visual Studio to copy it someplace else, the database will stay where it was when you browsed for it as shown above in Figure 2. In other words, the database *is* Northwnd.mdf, and it stays in the Data directory that is part of the samples.

Pablo,

The DataContext that is created by the LINQ to SQL Designer (aka the Object Relational Designer) has code for reading your config file. This code will be executed if you use the default constructor for the DataContext If you prefer to pass in your own connection string, you can use the second constructor for the DataContext, which takes a connection string as a parameter:

DataClasses1DataContext db =

new DataClasses1DataContext(MyConnectionString);

The samples that ship with the product, such as the Northwind sample, show how to use this second parameter, and how to construct a connection string that will work with it.

A question:

I successfully carried out the steps you gave, but I'm wondering exactly where the database *is*. I don't see it in bin\debug.

More generally, I'm wondering how deployment works. I want my app to carry its own little sqlexpress db with it, and populate itself from data in files on whatever computer it's running on.
