Answer 1

Simpler than you think. :)

var db = new SampleData.EventoDataContext();
db.MyTable.InsertOnSubmit(new MyTable() { ... });
db.Submit();

1. "MyTable" is the name of the table you defined inside the database.

2. Make sure you define a primary key, or inserting into the table will fail.

3. You will need to initialize your table inside the {...} part.

To get items from the table:

foreach (var item in db.MyTable.Where(x => x.SomeProp == 1))
{
//…
}

This will return all the rows where SomeProp is 1. You can now inspect item to see what the row contains.

Try to study the vici cool stored procedure. It is very very simple to create, add, and retrieve data from any db in WP7 applications
