.NET, C-sharp, and Mono
Mono and Moonlight are free software packages developed with help from Microsoft. Questions of their legal safety exist because both packages use ideas on which Microsoft holds patents. Microsoft has given limited reassurances, but they are far from complete.
Contents
Mono
What is it?
Mono is an implementation of the C# programming language and the Common Language Infrastucture as described by ECMA-334 / ISO/IEC 23270 and ECMA-335 / ISO/IEC 23271.
What reassurances has Microsoft offered?
The ECMA-334 and ECMA-335 are covered by the Microsoft Open Specification Promise and the Microsoft Community Promise.[1]
Avoiding Mono
- For note-taking, or a personal wiki, use GNote.
- To manage and edit collections of photos, use Shotwell or Solang or GQview.
Avoiding C#
Info sought: there is a langauge called "Vala" which aims to have the utility of C# without the patent problems.
Moonlight
What is it?
Moonlight is primarily a web-browser plugin which provides animation and interactivity features which can be used to develop web applications.
What reassurances has Microsoft offered?
In 2007, Microsoft published a "Covenant to Downstream Recipients of Moonlight".[2] A new promise was published in December 2009,[3] but it was criticised as being no improvement on the previous promise. The new promise also specifically excludes distributors from any patent protection.[4]
Avoiding Moonlight
Many features of HTML 5.0 have been designed to provide functionality which is offered by Moonlight. Here's some good info on HTML5.
