Meta-model-based implementation of Sudoku: Eclipse vs. Visual Studio

By considering Sudoku as a language, where a Sudoku puzzle is an instance of the language, we are able to apply meta-model-based technologies for the implementation of Sudoku, including correctness checking of a puzzle and solving strategies. The description of Sudoku includes not only the structure of Sudoku, but also covers constraints, textual representation, graphical representation, and behaviour (transformation and execution). We have created a meta-model-based description of Sudoku and use this as a basis for a comparative implementation in Eclipse with various plug-ins, and in Visual Studio with DSL-tools.
