Debugging during development

In this section, you will learn how to debug problems at development time.

Creating code with a deliberate bug

Let's explore debugging by creating a console app with a deliberate bug that we will then use the tools to track down and fix.

1. In Chapter04, create a folder named Debugging, add it to the workspace, and create a console application in the folder.
2. Navigate to View | Command Palette, enter and select OmniSharp: Select Project, and then select the Debugging project.
3. In the Debugging folder, open and modify Program.cs to define a function with a deliberate bug and call it in the Main method, as shown in the following code:

   using static System.Console;
   namespace Debugging
   {
     class Program
     {
       static double Add(double a, double b)
       {
         return a * b; // deliberate bug!
       }
       static void Main(string[] args)
       {
         double a = 4.5; // or use var
         double b = 2.5;
         double answer = Add(a, b);
         WriteLine...
