Any guarantees about patents? Can using and extending .Net will cause in the future claims of software patents violations?

  The absurdity of betting your livelihood on a Microsoft 'promise' aside, to me this reads as a green light to use, but not extend, the .NET runtime. MS still doesn't get free software, and probably never will. Edit: My bad. "As part of a .NET runtime" means you can extend it. But I'd be no less nervous about using it because it is not a license, merely a 'promise' with questionable legal weight.
