QuestionConvert .NET 4.5 method into .NET 2.0 using LinqBridge Pin
arnold_w14-Dec-17 2:39

This is a spin-off from the thread Efficiently sort the following? - Algorithms Discussion Boards , but specifically is about converting .NET 4.5 LINQ code into .NET 2.0 code using LinqBridge. The following code is using .NET 4.5 and works fine in Visual Studio 2013:
        public struct Record
        {
            public string column1 { get; set; }
            public string column2 { get; set; }
            public string column3 { get; set; }
        }

        public Form1()
        {
            InitializeComponent();

            Record[] UnsortedRecords =
            {
                new Record { column1 = "City",   column2 = "Florida",    column3 = "Miami"},
                new Record { column1 = "Animal", column2 = "Land",       column3 = "Dog"},
                new Record { column1 = "Animal", column2 = "Land",       column3 = "Rabbit"},
                new Record { column1 = "Food",   column2 = "Dessert",    column3 = "Chocolate Mousse"},
                new Record { column1 = "Food",   column2 = "Dinner",     column3 = "Hamburger"},
                new Record { column1 = "Animal", column2 = "Water",      column3 = "Fish"},
                new Record { column1 = "Animal", column2 = "Land",       column3 = "Cat"},
                new Record { column1 = "Food",   column2 = "Dessert",    column3 = "Cake"},
                new Record { column1 = "Animal", column2 = "Air",        column3 = "Bird"},
                new Record { column1 = "Food",   column2 = "Dessert",    column3 = "Ice Cream"},
                new Record { column1 = "Food",   column2 = "Dinner",     column3 = "Steak"},

                new Record { column1 = "Food",   column2 = "Dinner",     column3 = "Lasagna" },
            };

            IEnumerable<Record> SortedRecords = SortRecords(UnsortedRecords);
        }

        public static IEnumerable<Record> SortRecords(IEnumerable<Record> source)

            return source
                .GroupBy(r => r.column1, (key, items) => items

The code above works great, but I need to run it in Visual Studio 2005, that is .NET 2.0. I have downloaded LinqBridge.dll ( LinqBridge ) and added a reference to it and I have tried the following, but I get build errors:

            public string column2;

            public Record(string column1, string column2, string column3)
            {
                this.column1 = column1;
                this.column2 = column2;
                this.column3 = column3;
            }
        }
