An anonymous reader writes: Microsoft has announced their Community Promise regarding ECMA 334/335, which seems to be quite open and clear that C# can be freely implemented.
FTA: "It is important to note that, under the Community Promise, anyone can freely implement these specifications with their technology, code, and solutions. You do not need to sign a license agreement, or otherwise communicate to Microsoft how you will implement the specifications. The Promise applies to developers, distributors, and users of Covered Implementations without regard to the development model that created the implementations, the type of copyright licenses under which it is distributed, or the associated business model.
Under the Community Promise, Microsoft provides assurance that it will not assert its Necessary Claims against anyone who makes, uses, sells, offers for sale, imports, or distributes any Covered Implementation under any type of development or distribution model, including open-source licensing models such as the LGPL or GPL."
Apparently the subject of Mono was a hot topic at the Gran Canaria Desktop Summit in Richard Stallman's speech, and when asked if Microsoft could resolve the situation RMS said that Microsoft could come out and be more clear. Will Microsoft's announcement be enough to settle this issue finally?
