VS2015 Preview: Inline Rename

Another IDE experience that has been revamped in Visual Studio 2015 Preview is that of renaming stuff. You can rename a variable by right-clicking it and selecting “Rename…” from the context menu, or instead by simply hitting F2 on your keyboard:


When you do this, Visual Studio goes into Inline Rename mode. It finds all the instances of that variable and highlights them for you, while providing some other options on the side:


As you type a new name, all instances are instantly updated:


What’s really cool about this is that the IDE actually warns you if the new name conflicts with some other variable:


Just press Enter to accept the changes.

Although I have demonstrated how to rename a variable, this also works for other things such as methods and classes. In case of conflicts, Inline Rename will attempt to resolve them using fully-qualified names if possible, as demonstrated in the video with Beth Massi and Dustin Campbell.

VS2015 Preview: Potential Fixes and Preview

When there’s a squiggly line in your code due to some error or warning, Visual Studio 2015 Preview provides an improved experience in dealing with them. When you hover over the squiggly line, aside from the fancy coloured tooltip, you’ll also get a link saying “Show potential fixes”:


Once you click on that “Show potential fixes”, you are given a list of actions. Note that you can also get to this list by clicking on the light bulb next to the tooltip, or else pressing Ctrl+. (read: Control Dot) on the keyboard while the caret is on the squiggly line.


When an item in the list is selected (but before you actually accept it), you get a handy preview (similar to what we saw with the unused usings) showing how the code will change as a result of that action. This means you will know what effect any fixes and refactoring (which will be covered in later articles) will have on your code before you take the plunge.
