XNA documentation?

The install for Game Studio Express installs XNA documentation to your drive. There should be a start menu entry someplace, but if not, select some XNA type in Visual Studio and hit F1 and that will pull it up.

You can also find it Here, online. It's pretty much the same as the one that gets installed with Game Studio Express.

EDIT: You can find it through Game Studio Express. Open up GSE, clikc "Help -> Contents". This should open up a new help window. At the top left hand side, there should be a drop down menu that allows you to select different sets of documentation. There should be one for XNA there.

There is some of both there. The tutorials are under the "Getting Started With XNA Game Studio Express" section and also under the "Programming Guide" section.

It should be noted however that the XNA documentation is quite poor in comparison with some other programming guide. It doesn't tell much about using XNA in the correct way - so it shall be used more as a starting guide than like a real, full featured programming guide.

In the end, the XNA reference will be your best friend, but that means that you'll have to experiment a bit with XNA - there are some classes in the reference that are only documented in the reference, with now mention of their use in the programming guide. This is a poor decision from MS, as it can be challenging to learn how to use these classes correctly. But that's definitely possible...
