The inline debugging functionality facilitates the debugging procedure, as it lets you view the value of variables used in your source code right next to their usage, without having to switch to the Variables pane of the Debug tool window.
To enable the inline debugging functionality, in the Debug tool window toolbar click the Settings icon and select the Show Values Inline option from the popup menu. You can also enable this option from the Debugger. Data Views settings page.
If this option is enabled, when you launch a debug session and step through the program, the values of variables are displayed at the end of the lines where these variables are used.
