How Can I Efficiently Debug Function Return Values in Visual Studio?

Debug function return value in Visual Studio

Debugging can be challenging when the return value of a function is associated with a target, such as a data grid on an ASPX page. In particular, it can be inconvenient to check the return value before returning.

Visual Studio 2013 and earlier

Unfortunately, in Visual Studio 2013 and earlier, there is no direct way to check the return value of a function before returning. One workaround is to introduce a temporary variable to store the result. However, this can be tedious.

Visual Studio 2015

Starting with Visual Studio 2015, the $ReturnValue variable was introduced in the Watch/Immediate window. However, this feature is not available in subsequent versions.

Visual Studio 2017 and above

The $ReturnValue variable is back in Visual Studio 2017. It allows checking the return value immediately after the function call. To use it, just set a breakpoint on the function call and step through it using F10.

Visual Studio 2022 Instructions

In Visual Studio 2022, the $ReturnValue variable must be added to the watch window before executing the return statement.
