After having a week to work with the new Visual Studio Beta, I’m already missing some of the new features when I need to jump back over to 2010. Here are some of my favorites, in no particular order.
Quick Find

This is a frequently highlighted new feature, and I’ve definitely found it useful already as a quick shortcut for getting to almost any function in the IDE. My favorite part of it is that it’s so keyboard focused and allows me to skip reaching for the mouse to do things that I would normally just dig into a menu for. As a longtime SlickRun user, the keyboard shortcut to activate it also feels really natural (SlickRun uses Win+Q, Quick Find is Ctrl+Q) and the fast auto-complete search feels similar too.
Incremental Search feels right again

Although much of the new functionality was available previously through the Power Tools, a few of the things that got pulled in finally got that extra polish that makes them just feel right. One of the first Power Tools that I had turned off was the new unified Find box that took over a bunch of different functions and keyboard shortcuts. The big problem I had was the way it handled Ctrl+I incremental search. I use this so frequently that it’s a reflex and there were a few hiccups in keyboard focus that caused me to have to stop and figure out how to get back to the state I wanted to be in in the editor. Now, in the beta, this experience has been smoothed out, and the only noticeable difference from the old Ctrl-I functionality are the new visual cues: the box up top showing what I’ve typed, the extra highlighting of all matches in the current window, but the keyboard experience feels the same, and responds just like I expect.
Navigate To (Ctrl+,)

One of the things I miss most when working in a bare instance of Visual Studio that doesn’t have my two favorite extensions installed (CodeRush and ReSharper) is quick keyboard navigation to any type in my solution. The new Navigate To window provides a similar (though not identical) experience, with a search while typing listing of types and members, including camel casing caps shorthand, and instant navigation to the selected item.
Out of process solution load and build
This one is pretty obvious, but I know a lot of work went into this and it’s going to be such a dramatic time and frustration saver. Finally those extra cores are getting used on the big workloads.
TFS Local Workspaces
So many cool things about this, and I’ve only scratched the surface so far, but just the way this has been worked into the UI is really impressive. Like if you need to switch back and forth between Local and Server workspaces, there’s one button to click. Doing a Compare to the workspace version of the file just works the same, but doesn’t need to talk to the server at all, so is much faster. No more worrying about accidentally changing a file from outside VS and getting out of sync – now VS is watching and will pick up the change for you. Just all around a well thought out experience and hits a lot of the big annoyances people have with using TFS source control.
New Diff tool
Finally, the Visual Source Safe compare window is gone. A lot here is similar to other diff tools that you could previously point TFS to for your comparisons, but being built in not only skips that extra configuration, but also gives you the full VS editor. Editing a file right in the compare window with full syntax highlighting, Intellisense, and even instant updates of the compare state feels like magic after so much time spent with the old one. The UI isn’t the only part that’s changed either. TFS auto-merging is much improved too and should cut down dramatically on the number of times you even see the merge window.
