F.4. Creating DLL assemblies using csc.exe

If you are using csc.exe, you will need to know how to reference classes coded in other assemblies using the /reference option.

Let's say you have two classes, called MyClass1 and MyClass2, in separate source files. ^[4] MyClass1 creates a new instance of MyClass2 in its Main method.

^[4] Of course, you can put them into the same source file and no referring will be required. But I am trying to show how you can reference something coded in another source file (which will eventually be compiled into a separate assembly).

1: // MyClass1.cs
2: public class MyClass1{
3:   public static void Main(){
4:     MyClass2 mc2 = new MyClass2();
5:     System.Console.WriteLine(mc2.Add(3,4));
6:   }
7: }
