Microsoft finally released the source code
for .NET as promised. Nothing new, so why are you resurrecting a 3-months old topic? Because they introduced a change in the license that affects the Mono Framework. Quotable quote:
The .NET Framework source is being released under a read-only reference license. When we announced that we were releasing the source back in October, some people had concerns about the potential impact of their viewing the source. To help clarify and address these concerns, we made a small change to the license to specifically call out that the license does not apply to users developing software for a non-Windows platform that has “the same or substantially the same features or functionality” as the .NET Framework. If the software you are developing is for Windows platforms, you can look at the code, even if that software has "the same or substantially the same features or functionality" as the .NET Framework.
I wonder if this means that the guys working at Novell in Mono can actually use the source code as a reference for improving Mono. Hmmm, the blog entry is now 10 days old, but Miguel de Icaza didn't comment anything in his weblog.
EDIT: OK, on second reading, the quote appears to me to specify the contrary to what I thought at first. DO NOT look at the code if you're developing something outside Windows. And it actually makes sense
