i'm beginner with farseer, i want some help to accomplish this :

i have a 2D game , no gravity , and a player, i want when i press the directional buttons (right - left - up - down) to make the player advance to that direction AND rotate to it , just like a car , it rotates to the desired direction while moving to it ..

When you are trying the move your player with no gravity, you are going to want to use Body.ApplyForce() to move the player around. Then, you can calculate the rotation based on the direction it is moving.

If you are making a car simulation this tutorial could be useful (made for the original Box2D in c++):

Some other great tutorials are found on this site (click on the tag Box2D  they are for the Flash port of Box2D):

Since those are not .NET/Farseer tutorials you might have some trouble if you don't read c++ or ActionScript but the concepts are exactly the same.
