How Can I Inspect Function Return Values During Debugging in Visual Studio?

Inspecting function return values ​​while debugging in Visual Studio

When debugging a function, it is very useful to be able to inspect the return value of the function before it actually returns. This is especially useful when troubleshooting a problem or trying to understand the behavior of a specific function.

In Visual Studio, you can check the return value in the Immediate Window or Automated Window. To do this, just add the variable name $ReturnValue or $ReturnValue1 to the Immediate Window, or expand the ReturnValue property in the Automatic Window after setting a breakpoint.

However, it is important to note that this feature has been removed in Visual Studio 2015. If you are using Visual Studio 2015, you will need to use a temporary variable to check the return value, or you can upgrade to Visual Studio 2017, where this feature is available again.

In Visual Studio 2022, you can inspect the return value of a function using the name $ReturnValue in the Watch window. However, it must be added to the Watch window before executing to the "return" statement for this to work properly. This feature is not available in earlier versions of Visual Studio.
