You scrambling up completely different technologies which really don't have much in common. Sometimes you'll be using them beside each other, but other then that, they don't really mesh.

First of all, WinFX is an API to represent graphical user interfaces differently that how they would normally look. The WinFX is something new coming in .NET 3.0 . Second of all, Direct3D and OpenGL are graphics APIs which can bind your program up to hardware to provide 3D hardware accelerated graphics. The Win32 API is used to create basic windows and stuff and if you're using the .NET Framework, it's already wrapped up for you in nice classes.

A 3D engine would require a vast amount of knowledge and experience to make and considering the questions you've asked, I don't think you have nearly enough of both to create a good 3D engine. My recommendation then would be to go out and try all three of those technologies individually before moving on. See which is which, where to use each one, how they differ. Once you're familiar with the technology itself, then you can use it.

Hello there!
I want to make a WIndow framework for a new 3D Engine.
I want to make the basic functions. Create the window.. Init Direct3D... Init OpenGL.. switch between the two APIs... Detect the available display modes.. Detect AA.. AF ... etc
But i am confuzed with the WinFX stuff...
What is gonna be the difference when I will use WinFX?

I will say this for everyone's benefit: For god's sake don't try to combine WinFX and Direct3D unless you have a really good reason to do so.

WinFX and more specifically Avalon provide a ton of really really cool things right now, but it is terribly wrought with nasty gotchas when it comes to integrating with hardware accelerated 3D viewports. Stick to WinForms and render to a regular window unless you damn well know what you're doing. Using Avalon controls along with D3D is possible, to some extent, if you're very careful and you follow all the rules -- most of which don't seem to be well documented publicly and some of which are probably not written in stone.

To make a long story short, don't try any of this until Vista and WinFX are released, at the very least. WinFX on its own is great, but you're asking for trouble if you try to combine Direct3D with it. If you really, really want to do this, then go learn Avalon for a while, then once you're comfortable with just that, then we can talk.
