10/50 System.Console.WriteLine() example mscorlib is required by CLR so no reference is required in code

11/50 Compiling and running The 4.0.NET Framework must be installed on the computer that will run a 4.0 Assembly (EXE) Use C# compiler to create hw.exe Running assembly invokes JIT by CLR and runs app

12/50 using keyword for Namespaces static keyword means you don’t need an instance of the class Program to call the function Main.

Create the … Data access layer and tests, debug Business logic layer and tests, debug Presentation layer and connect to business layer, debug 4. Test the application 5. Create installer 6. Deploy application to users 7. Repeat until all application features are complete
