Question

I am new to the entity framework and wondered, when the data is actually taken from the database. If I e.g. does:

from order in orderQuery where order select car;

is the data then selected from the database, or is it first when I manipulate it like the code below?

(from order in orderQuery where order select car).ToList(); 

Answer 1

LINQ queries have a property called delayed execution. This separates out the building and execution of a query into 2 distinct parts. The first example you gave only defines a query and hence won’t cause any execution. The second however will force the query to run to completion
