Visual Studio 2010 also includes some nice new “DataTip pinning” features that enable you to better see and track variable and expression values when in the debugger.
Simply hover over a variable or expression within the debugger to expose its DataTip (which is a tooltip that displays its value) – and then click the new “pin” button on it to make the DataTip always visible:
Also, you can even enter comments for a pinned data tip, so that you can view the comment later.
You can “pin” any number of DataTips you want onto the screen. In addition to pinning top-level variables, you can also drill into the sub-properties on variables and pin them as well.
Another great thing is Pinned DataTips are usable across both Debug Sessions and Visual Studio Sessions:
Pinned DataTips can be used across multiple debugger sessions. This means that if you stop the debugger, make a code change, and then recompile and start a new debug session - any pinned DataTips will still be there, along with any comments you associate with them.
Pinned DataTips can also be used across multiple Visual Studio sessions. This means that if you close your project, shutdown Visual Studio, and then later open the project up again – any pinned DataTips will still be there, along with any comments you associate with them.
See the Value from Last Debug Session:
DataTips are by default hidden when you are in the code editor and the debugger isn’t running. On the left-hand margin of the code editor, though, you’ll find a push-pin for each pinned DataTip that you’ve previously set-up.
Hovering your mouse over a pinned DataTip will cause it to display on the screen. Below you can see what happens when I hover over the first pin in the editor - it displays our debug session’s last values for the “Request” object DataTip along with the comment we associated with them
Importing/Exporting Pinned DataTips:
Pinned DataTips are by default saved across Visual Studio sessions (you don’t need to do anything to enable this).
VS 2010 also now supports importing/exporting pinned DataTips to XML files – which you can then pass off to other developers, attach to a bug report, or simply re-load later.
VS 2010 has also got a tone of other Debugger Enhancements, read about them from Scott Gu’s blog if you are interested.
