![]() F10 advances the debugger without stepping into functions or methods in your app code (the code still executes). Notice this time that the debugger does not step into the SendMessage method. While paused at the method call, press F10 (or choose Debug > Step Over) once. Press F11 several times until you get back to the SendMessage method call again. You should be back in the For loop in the Main method, paused at the SendMessage method call. This command resumes app execution (and advances the debugger) until the current method or function returns. You can do this using the Step Out command. Let's say that you are done examining the SendMessage method, and you want to get out of the method but stay in the debugger. (To move faster through code, we show you some other options also.) By default, the debugger skips over non-user code (if you want more details, see Just My Code). F11 is a good way to examine the execution flow in the most detail. The yellow pointer advances into the SendMessage method.į11 is the Step Into command and advances the app execution one statement at a time. Press F11 one more time to step into the SendMessage method. While paused in the For loop in the Main method, press F11 (or choose Debug > Step Into) twice to advance to the SendMessage method call.Īfter pressing F11 twice, you should be at this line of code: Mostly, we use the keyboard shortcuts here, because it's a good way to get fast at executing your app in the debugger (equivalent commands such as menu commands are shown in parentheses). Navigate code in the debugger using step commands Press F5 ( Debug > Start Debugging) or the Start Debugging button in the Debug Toolbar, the app starts, and the debugger runs to the line of code where you set the breakpoint. For information on the different types of breakpoints you can set, such as conditional breakpoints, see Using breakpoints.Ī red circle appears where you set the breakpoint. Otherwise, F5 continues running the app to the next breakpoint.īreakpoints are a useful feature when you know the line of code or the section of code that you want to examine in detail. If the app is not yet running, F5 starts the debugger and stops at the first breakpoint. The yellow arrow represents the statement on which the debugger paused, which also suspends app execution at the same point (this statement has not yet executed). , the app starts, and the debugger runs to the line of code where you set the breakpoint. A breakpoint indicates where Visual Studio should suspend your running code so you can take a look at the values of variables, or the behavior of memory, or whether or not a branch of code is getting run. In the For loop of the Main function, set a breakpoint by clicking the left margin of the following line of code:īreakpoints are one of the most basic and essential features of reliable debugging. Private Shared Sub SendMessage(ByVal name As String, ByVal msg As Integer)Ĭonsole.WriteLine("Hello, " & name & "! Count to " & msg) In Program.vb, replace all of the default code with the following code instead: Imports Systemĭim letters As Char() = įor i As Integer = 0 To letters.Length - 1 On the Additional Information window, ensure the recommended target framework is (.NET 6.0), and then choose Create. In the Configure your new project window, type or enter get-started-debugging in the Project name box. Then, in the Visual Studio Installer, choose the. In the Not finding what you're looking for? message, choose the Install more tools and features link. If you do not see the Console Application template, you can install it from the Create a new project window. F# and JavaScript do not support the Autos window). If this is the first time that you've tried to debug code, you may want to read Debugging for absolute beginners before going through this article.Īlthough the demo app is Visual Basic, most of the features are applicable to C#, C++, F#, Python, JavaScript, and other languages supported by Visual Studio (F# does not support Edit-and-continue. ![]() You can step through your code and look at the values stored in variables, you can set watches on variables to see when values change, you can examine the execution path of your code, see whether a branch of code is running, and so on. When you do this, the debugger provides many ways to see what your code is doing while it runs. ![]() When you debug your app, it usually means that you are running your application with the debugger attached. If you want a higher-level view of the debugger features, see First look at the debugger. This article introduces the features of the Visual Studio debugger in a step-by-step walkthrough.
