How do I draw a 2d box on the screen? Or even better a 2d circle.
I guess I should use DrawPrimitives but a little example would be nice..
After that I would like to draw some text, do I need to create a bitmapped font for that and draw using sprites?

I wrote a line manager today (3d), but it was not very easy ..
Hopefully there will be more helper classes available to draw boxes, lines, and simple stuff directly without having to create custom formats, vertex buffers and doing all the low level stuff.
There is also no font support, not only single class will help you out with that. You have to do your own bitmapped font stuff, again not very easy right now. Need more helper classes ^^
"Content". In the sidebar that appears on the left, you'll see an "XNA"

Now you should see a sub-category titled "XNA Game Studio Express". Expand that category.
Below that category you'll see a sub-category titled "Getting Started with XNA". Expand that category.

Also, look at this thread for some other tutorial advice and sites.
I know it's harder than drawing a sprite, thats why I would like some help :)
I would like to use XNA for prototyping, and I think drawing boxes and circles is much better when the design isn't finished. You can scale them to any size and quickly add stuff from code. When you have a working fun game with boxes and have decided what size they need to be you can start drawing or hire an artist.

By the time you are done with their tutorial, you should be able to draw a 2D sprite on the screen and have it move around.Also, look at this thread for some other tutorial advice and sites.

I just addressed this issue in another thread, so rather than repeat myself, I'll just point you at it:
The long and the short of it is that I wrote a font helper class that you might find useful.
I was just looking through some of my old Managed DirectX projects trying to convert various parts to XNA and figuring out how to draw a line in XNA was one thing that I'm not having an easy time converting. I started to go down the path of using DrawPrimitives and was able to get a line drawn on the screen but I had no control over. It seemed like the fact that I got a line at all was more of a fluke than anything because I was just setting parameters to see what they changed without really understanding what each one meant. Has anyone else been playing around with drawing lines to the screen and want to share the method they used? I'm going to keep playing with it, but I've gotten about as far as I'm going to without discovering some new information that makes a solution click for me, so feel free to offer up any advice at all to point me in the right direction. Thanks for any help or advice you can give.
I haven't tried it but hopefully it's useful.

Thanks for the link, Greg. I wrote a little class for rendering lines (2d,3d), the BoundingBox and BoundingSphere from the XNA framework :
http://markus.rubicon-net.de/code/
VectorRenderer.cs, it just needs a reference to the GraphicsDevice and the view-projection matrix of your scene.
Since the API does not yet support a simple static method
like DrawShapes.Line(point A, point B), what about drawing a basic sprite with
the proper rotation.
mySpriteBatch.Draw(mySprite, picBox, picBox, Color.Red, rotationRad, vOrig,SpriteEffects.None, 0);
All you need is a tiny bit of trigonomic magic to calculate the rotation and
the dimensions of your rectangle.This
completely avoids the need for vertices and shading and matrixes and the like.(any help with trig magic is appreciated)
Here is what I have done so far.
sprite rendered and moving on the window with a background image.
the dimensions of the sprite rectangle so that the height is one or two pixels.This will squish any image into a nice
line.
version of the mySpriteBatch.Draw() method that includes the rotation
parameter.So far I have just hard coded
values.
To Do:
a class that accepts two coordinates.
the delta x and delta y between the coordinates.
the length and rotation of my sprite rectangle. The height will be one or
two pixels.
