Golden.Man.Sudoku.Solver (nuget): This is a portable and lightweight Sudoku solver implementation in C#.  How to use  int[,] grid = {     {0, 0, 0, 0, 0, 0, 0, 6, 7},     {0, 0, 0, 9, 0, 7, 4, 0, 3},     {0, 6, 0, 0, 0, 0, 1, 9, 0},     {1, 0, 0, 0, 7, 3, 0, 0, 0},     {0, 0, 0, 4, 0, 6, 0, 0, 0},     {0, 0, 0, 8, 1, 0, 0, 0, 4},     {0, 2, 1, 0, 0, 0, 0, 5, 0},     {8, 0, 7, 1, 0, 9, 0, 0, 0},     {3, 5, 0, 0, 0, 0, 0, 0, 0} };  bool solved = SudokuSolver.Solve(grid);  if (solved) {     // Print out the solution     for (int i = 0; i < 9; i++)     {         for (int j = 0; j < 9; j++)         {             Console.Write(grid[i, j] + " ");         }         Console.WriteLine();     } } else {     Console.WriteLine("No solution"); }
