Reviews for this release

You know what I was doing on October 31, 2009? Trick or treating. I was 6 years old in 2009. But this is a good version. I like making operating systems because it makes me know I'm going places when I'm older. I'm currently 12 years old.

Awesome Software!

A good system. I found a few bugs while compiling fine code from the older milestone 3. Still, i look more forward to milestone 5. The only new is the compiler speed - of changes that are detectable. The new speed helps you - you don´t go and get a coffee before it is done. Good things: Compiler speed Some crash fixes Expected in next release: Image support Mouse support Sound support

Very cool project. I'm reserving two stars for the release which will support the .Net TCP/IP methods.

Great project! Waiting for Milestone 5. One thing that I miss very much, is a shutdown function. But thats no big problem @ moment (:

Awesome project but will be a lot of work! I am sure this will help many people to learn how to build an OS using a .Net language! Also a nice project which will perhaps change a lot in a few years is ReactOS! but just written in C and partly c++.

Yes, better compiling speed.

Great work! Nice to see that you're still working on this :P

It's great to see you guys are still developing this. Hope to see the multi-decimal arrays working in the next milestone :) Also any one mind telling me how to compile the source code?

I havent tried it yet lol

It installs correctly, but only to Visual C# Express. I have both VB.NET and C# installed, and I wish it would install on both of them... but that's minor. The only thing I ever get when building is a "plug needed" error message... but that's probably my fault.
