    [SOUND] Although no one likes to admit it, we all know that 0:00
    when we're writing code, we're also introducing bugs. 0:04
    Some bugs can be resolved simply by looking up the relevant code and 0:10
    making a quick change. 0:13
    However, most bugs are usually more complex and difficult to locate. 0:15
    That's where debugging comes in. 0:19
    So, what is debugging? 0:21
    I think Wikipedia describes it best. 0:23
    Debugging is the process of finding and resolving defects that prevent 0:25
    correct operation of computer software or a system. 0:30
    In this workshop, we'll take a look at how to debug an application 0:34
    using the powerful Visual Studio ID from Microsoft. 0:37
    Before we dive in, let's take a quick look at the application we'll be using for 0:41
    this workshop, called SongList. 0:45
    SongList is a simple console application for users to list their favorite songs. 0:48
    The main method entry point is located in program.cs. 0:53
    It's responsible for managing application state, 0:56
    getting user options, and displaying the list of songs the user has added. 1:00
    Song.cs is a simple song model. 1:03
    Menu.cs and CLI.cs contain static methods for 1:06
    displaying text and prompting for input from the user. 1:12
    When running the app, we'll see a menu with three options. 1:15
    Add song, view list, and quit. 1:19
    First, let's add a new song using option one. 1:23
    I'll enter Learning to Fly. 1:28
    By Tom Petty. 1:33
    Then we're asked if we'd like to add another song. 1:36
    I'll type n for no. 1:39
    And we're back to the option menu. 1:41
    Let's confirm our song has been added to the list by using option two. 1:43
    There it is. 1:48
    This is a very simple application. 1:51
    So it doesn't persist our songs when we exit the app. 1:53
    But this is all we need to learn about debugging in Visual Studio. 1:57
    So let's get started. 2:00
