No, the .NET Framework is not part of Windows XP. It is part of 2003 Server, but I doubt many people are using that on their desktop!
And I won't hear a bad word said about it. Heck, I'm an old C/UNIX hacker who generally can't stand Microsoft stuff on religious grounds, and even I quite like it for coding.
If it helps anyone, there is direct link here:
.NET Framework 1.1
It's about 20Megs, so a big download if you're on dial-up unfortunately.
Oh, and Zell you can see graphical previews of flats and DOOM format graphics from the 'View' context menu. Which is perhaps a bit long winded, but is on purpose as the central editor knows nothing about the lumps themselves.
You can also configure it to launch the graphics viewer on double clicking a lump if it helps.
And thanks for the kind comments on stabilty, but that's probably more down to C# and .NET being managed code, so it does lots of nice tidying up for the programmer
I've not added anything for previewing sounds and music as there is nothing in the .NET Framework for that (unless you use Managed Direct X I think). I'm trying to keep it in a state where it shouldn't need much porting if any of the free .NET UNIX implementations finally complete their version of the Windows Forms stuff.
