Novell’s Mono 1.2 Press Release mentions that the project adds support for Windows Forms.
That was fast. I’m neither a Microsoft nor a Novell customer. Now I’m curious, though; does this software infringe Patents #6,920,461 and #6,959,294? (Note that, at least per my reading of the former, Microsoft has only patented the interface.)
(Note two: if you might work on Mono or a similar project in the future, and if U.S. patent laws apply to you, erase the fact that I mentioned those patents from your head entirely. Then contact your representative legislators to complain that a single sentence I wrote here may make you liable for treble damages someday.)
