Cool, I suppose. But, uhm...
To be honest I have to admit that the integration of Office development within Visual Studio 2012 is actually pretty slick, that is of course if you're into this kind of thing. Which I am, sort off. I got VS2012 Professional, the Office SDK is a free download and then all you need is a version of Office installed.
The thing is; wouldn't it make more sense to start by fixing our interface and feature set before adding new "cool" stuff ?
Many VS2012 developers are anxiously awaiting VS2012 Update 2 which, among several other bugs, also fixes bugs with the (hastily) released blue theme in the theme editor. Sometimes you get black letters on a dark blue background. Which really isn't all that easy to read; and according to the update description its something Microsoft has also come to realize.
But there's more... Microsoft wants us to use their tools to make cool apps. But at the same time they also want to prevent us from doing so.. Sounds strange? Read on..
One of the tools in their discontinued Expression series is Microsoft Blend; a tool which you can use to make "dynamic interfaces" (to put it easy; more info on the website). But, as mentioned, its discontinued and instead embedded with VS2012. You can see on the site itself; instead of being able to download Blend you're pointed at downloading Visual Studio.
And there's the problem; at the moment of writing there is only a Blend version for Windows Phone development or Windows 8 ('app') development. People new to VS2012 who want to utilize Blend for Silverlight or WPF editing are pretty much out of luck; Blend as a stand alone product is gone and there is no full integration with VS2012 as of yet.
There is, however, the previously mentioned upcoming update 2. One of its feature enhancements is Blend for Visual Studio 2012: "Support for Sketchflow, WPF, and Silverlight". All good and well; but what about people who need this tool right now? Well, as said they are out of luck: because if you read closely the update is merely a so called Community Technology Preview (CTP). Put differently: this is merely for testing purposes only, the Team Foundation Server update is the only part which has gotten a "go-live" remark. You're not supposed to use this VS2012 CTP update in a production environment.
So basically Microsoft dumped a tool (Microsoft Blend) while stating that Visual Studio 2012 would be the new all-in-one solution which would provide Blend functionality yet hasn't managed to release it just yet.
Just like they did with Expression Web (mentioned on that same Expression website). VS2012 is supposed to provide all you need for website design / editing. Well; at the time of writing you're IMO better off using Expression Web for your web design where VS2012 can come in handy with programming the underlying logic. It does not provide the same functionality right now.
So summing up: a half-baked interface (don't get me started on the colour removal!) combined with an as-of-yet unfinished feature set. Where people currently using VS2010 (with or without extra "supporting" tools) have a fully complete and functional programming environment.
And they're wondering what is keeping all those developers to embrace these shiney new tools?
