After years away from writing code in a Windows app, I want to resurrect a 1990s-era Visual Basic desktop app and 'refactor' it in C#. These sessions show me that I can enjoy doing what I did back then in a much more efficient manner. I am also hoping to find sessions that demonstrate how to call Windows functions in the various DLLs that comprise Windows today, and save even more code writing.
2:19 Concept 8:50 LINQ on T var nums = new List() { 1, 2, 3, 4, 5 }; IEnumerable queries = from num in nums where num > 3 select num; queries.ToList().ForEach(x => Console.WriteLine(x));
