Hello,

1. What happens when I declare DataContext dc = new dataContext ?
I want to know this, because it seems to take a few seconds to pass this statement.

2. Do I declare a new DataContext everytime I open an new form, or do I use the same one and pass this as a parameter?

3. Is it possible to have more datacontext's in 1 project; each with its own set of tables? Or is it wiser to have 1 dataontext with all tables ?

Thanks

1. The Metadata initialization occurs, and the parameters of stored procedures are queried, if
any procedures are present in the context.
2. This is a matter of controversy. Microsoft states that DataContext class is designed to implement
the "unit of work" pattern here in MSDN:

We don't have a unified solutuion, it depends on the purposes of your application.
3. You can use several datacontexts if you wish. This question also does not have any definite answer.
