This tutorial introduces the debugging tools available in Visual Studio for Mac.
Prerequisites
Use Debug build configuration
Debug and Release are Visual Studio's built-in build configurations. You use the Debug build configuration for debugging and the Release configuration for the final release distribution.
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.
By default, Visual Studio uses the Debug build configuration, so you don't need to change it before debugging.
Set a breakpoint
A breakpoint temporarily interrupts the execution of the application before the line with the breakpoint is executed.
![]() Use the Immediate window
The Immediate window lets you interact with the application you're debugging. You can interactively change the value of variables to see how it affects your program.
Set a conditional breakpoint
The program displays a string that the user enters. What happens if the user doesn't enter anything? You can test this with a useful debugging feature called a conditional breakpoint.
Step through a program
Visual Studio also allows you to step line by line through a program and monitor its execution. Ordinarily, you'd set a breakpoint and follow program flow through a small part of your program code. Since this program is small, you can step through the entire program.
Use Release build configuration
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 negatively affect the behavior of an application. For example, compiler optimizations that are designed to improve performance can create race conditions in multithreaded applications.
To build and test the Release version of the console application, do the following steps:

This tutorial shows how to create and run a .NET Core console application using Visual Studio for Mac.
Note
Your feedback is highly valued. There are two ways you can provide feedback to the development team on Visual Studio for Mac:
Prerequisites
Create the app
Create a .NET Core console app project named 'HelloWorld'. Canon scanner software mac high sierra.
The template creates a simple 'Hello World' application. It calls the Console.WriteLine(String) method to display 'Hello World!' in the terminal window.
The template code defines a class,
Program , with a single method, Main , that takes a String array as an argument:
![]() Main is the application entry point, the method that's called automatically by the runtime when it launches the application. Any command-line arguments supplied when the application is launched are available in the args array.
