 ## Prerequisites
 
 This tutorial works with the console app that you create in [Create a .NET console application using Visual Studio Code](with-visual-studio-code.md).
 
-## Use Debug build configuration
-
-*Debug* and *Release* are .NET's built-in build configurations. You use the Debug build configuration for debugging and the Release configuration for the final release distribution.
+## Set a breakpoint
 
-In the Debug configuration, a program compiles with full symbolic debug information and no optimization. Optimization complicates debugging, because the relationship between source code and generated instructions is more complex. The release configuration of a program has no symbolic debug information and is fully optimized.
+A *breakpoint* temporarily interrupts the execution of the application before the line with the breakpoint is run.
 
-By default, Visual Studio Code launch settings use the Debug build configuration, so you don't need to change it before debugging.

 1. Start Visual Studio Code.
 
 1. Open the folder of the project that you created in [Create a .NET console application using Visual Studio Code](with-visual-studio-code.md).

-A *breakpoint* temporarily interrupts the execution of the application before the line with the breakpoint is run.
-
 1. Open the *Program.cs* file.
 
 1. Set a *breakpoint* on the line that displays the name, date, and time, by clicking in the left margin of the code window. The left margin is to the left of the line numbers. Other ways to set a breakpoint are by pressing <kbd>F9</kbd> or choosing **Run** > **Toggle Breakpoint** from the menu while the line of code is selected.
 
    Visual Studio Code indicates the line on which the breakpoint is set by displaying a red dot in the left margin.

 Once you've tested the Debug version of your application, you should also compile and test the Release version. The Release version incorporates compiler optimizations that can affect the behavior of an application. For example, compiler optimizations that are designed to improve performance can create race conditions in multithreaded applications.
