There you have it.

Microsoft has just moved its chess piece (or "cheese trap") by supposedly opening up .NET. .NET is bound to become shared source. The OSI debate is not very relevant here (shared source isn't acceptable as "Open Source", yet), but the 'SCO factor' now comes into play. In an excellent new article, Steven Vaughan-Nichols explains why the cat is out of the bag.

Mono is sponsored by Novell. It's led by noted open-source developer Miguel de Icaza. The Mono code is covered by three different real open-source licenses. The C# Compiler and tools are released under the terms of the GPLv2 (GNU General Public License); the runtime libraries are under the LGPL 2.0 (GNU Library GPL 2); and the class libraries are released under the terms of the MIT 11 license.

Microsoft, however, is baiting its trap for Mono programmers with .NET cheese. They'll claim, come that day, about how open it was in letting people look, but not touch, their code. With the combination of "proof" that some Mono code has been stolen from Microsoft and its attempt to muddy the waters about what open source really means, it can look forward to having a much better chance of killing off an open-source project than SCO ever had with Linux

If you ever, and I mean ever, want to write open-source code, I recommend you not come within a mile of Microsoft's .NET Framework code or any other similar projects that the boys from Redmond "open" up.

If you do, you're nibbling on the cheese of a trap that will eventually snap shut on you and kill up your program and quite possibly your job and finances.

While Novell is betting on Mono, it would be dangerous to bet on Novell.

No mo', Novell

Update: Miguel de Icaza praises Microsoft about the move but cannot hide his disappointment with the choice of licence. It is subtle, yet transparent.

Does this disruptive development finally show everyone why Novell's love affair with Mono isn't such a great idea? Does it teach us just why Novell, which fosters this project and makes its desktop more Mono-oriented, doing it for selfish interests? Only Novell is 'protected' for the use of Mono (this protection will last for another 4 years and then expire). Even Xandros and Linspire are not 'protected' (Mon is excluded explicitly in their deal with Microsoft).

Microsoft is fooling everyone and works with Novell on poisoning the well we all drink from.
