Cannot step into method when debugging, no symbols found when symbols do exist VS Pro 15.4.4 windows 10.0 visual studio 2017 version 15.4 debugger. When stepping into a single statement, the debugger will step into each individual function invoked by that statement and each trigger fired by that statement. The order in which they are debugged is the same order in which the MySQL server executes them.

This article introduces the features of the Visual Studio debugger in a step-by-step walkthrough. If you want a higher-level view of the debugger features, see First look at the debugger. When you debug your app, it usually means that you are running your application with the debugger attached. When you do this, the debugger provides many ways to see what your code is doing while it runs. 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. 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.
Although the demo app is C++, most of the features are applicable to C#, Visual Basic, F#, Python, JavaScript, and other languages supported by Visual Studio (F# does not support Edit-and-continue. F# and JavaScript do not support the Autos window). The screenshots are in C++.
In this tutorial, you will:
Prerequisites
You must have Visual Studio 2019 installed and the Desktop development with C++ workload.
You must have Visual Studio 2017 installed and the Desktop development with C++ workload.
If you haven't already installed Visual Studio, go to the Visual Studio downloads page to install it for free.
If you haven't already installed Visual Studio, go to the Visual Studio downloads page to install it for free.
If you need to install the workload but already have Visual Studio, go to Tools > Get Tools and Features.., which opens the Visual Studio Installer. The Visual Studio Installer launches. Choose the Desktop development with C++ workload, then choose Modify.
Create a project
First, you'll create a C++ console application project. The project type comes with all the template files you'll need, before you've even added anything!
Create the application
Start the debugger!
Set a breakpoint and start the debugger
Navigate code in the debugger using step commands
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 using Run to Click
Restart your app quicklyDev C++ Tutorial
Click the Restart button in the Debug Toolbar (Ctrl + Shift + F5).
When you press Restart, it saves time versus stopping the app and restarting the debugger. The debugger pauses at the first breakpoint that is hit by executing code.
The debugger stops again at the breakpoint you previously set inside the
for loop.
Inspect variables with data tips
Features that allow you to inspect variables are one of the most useful features of the debugger, and there are different ways to do it. Often, when you try to debug an issue, you are attempting to find out whether variables are storing the values that you expect them to have at a particular time.

In this tutorial, you've learned how to start the debugger, step through code, and inspect variables. You may want to get a high-level look at debugger features along with links to more information.
