What’s new in Visual Studio 2010 – more than you may realise

I’m beginning to think Microsoft has under-sold Visual Studio 2010. Of course it is a huge product, as I observed back in October, especially since it includes a major new release of the .NET Framework as well as updated tools, but I thought I had discovered most of the significant new features. Still, when I sat down recently to write up an extended review, I found a lot that I had missed.

One of my reflections on this is that Microsoft has done of poor job of communicating what is new. I attended the Professional Developer’s Conference in 2008 and 2009. The developer-focused keynote on the second day last November should have hyped the best of what is new; but instead we got Steven Sinofsky on Windows 7 quality control – hardly the most exciting of topics – a sneak preview of IE 9, an unconvincing tour of Sharepoint and Office 2010, and Scott Guthrie on Silverlight 4. Guthrie was fantastic, leading us blow by blow through Silverlight’s new capabilities, but much else was neglected.

It doesn’t help that Microsoft’s home page for Visual Studio 2010 has meaningless headlines. “Set your ideas free”, “Simplicity through integration”, “Quality tools help ensure quality results.” Pure fluff, which saps your will to read further.

Here are a few things that I found interesting – nothing like comprehensive, just features that perhaps have not had the attention they deserve.

Microsoft F# – a new language from Microsoft Research, integrated into Visual Studio with remarkable speed. The people I’ve spoken to who have taken the time to discover what it does are truly enthusiastic. Some of its strengths are parallelism, asynchronous programming, graphics manipulations, and maths. You probably won’t write a complete application in F#, but it will be great for assembling libraries.

Windows Workflow Foundation 4.0 – potentially a new and effective approach to visual programming and long-running state management. Flow charts are often used to teach programming, since they express common concepts like if conditions visually. WF lets you draw a process as a flow chart – or there are other types of chart – using the nice new WPF design tools, and then execute it in the runtime, which is part of the “Dublin” extensions to IIS, now known as Windows Server AppFabric (I have no clue why this confusing name was chosen). To get the idea, I suggest reading David Chappell’s Workflow Way. For applications that fit this kind of model, it is a compelling approach, and integrates well with Windows Communication Foundation for messaging.

Dotfuscator – I know this is a third-party thing, but this is no longer just a tool for obscuring your .NET assemblies in the hope of preventing decompilation. The new Dotfuscator does runtime analytics, and can report back to a portal when your application runs, what features you use, what operating system it is on, whether it crashed, and so on. It also supports application expiry, known as “shelf life”, and can detect if assemblies have been tampered with. Some of this sails close to the spyware wind, but this is a matter of getting informed user consent. These are interesting features for Windows desktop developers, if there are any left, and even the free edition is quite capable.

Test and Lab management – a challenge to set up and configure, but when it works, amazing. Lab Management uses Visual Studio, Hyper-V and System Center Virtual Machine Manager to automate deploying an application over one or more VMs, so you can run tests against it. This hooks into Team System so you can file a bug report with a link that actually shows the bug happening at runtime, with a snapshot of the virtual environment.

Step backwards through code – IntelliTrace is a new feature of the Visual Studio debugger. Configure it to collect IntelliTrace events and call information, and you can then step backwards as well as forwards from a breakpoint, examining variable values as they change.

Team Foundation Server Basic – what this means is that even a solo Visual Studio developer can have TFS running locally or on a networked machine for source code management, issue tracking and so on. It’s worth considering because of the way it integrates with the IDE. I admit, I still like Subversion which I have on a remotely hosted server, since it acts as an effective off-site backup, but I’d much rather use TFS Basic than nothing.

UML – Microsoft has finally done what it should have done years ago, and implemented a wide range of up-to-date UML diagram tools. Nothing revolutionary, just useful.

Not everything is wonderful in the new Visual Studio. Deploying to Azure remains clunky in Beta 2 – when is this going to get better? SharePoint is another one; I appreciate the value of F5 debugging, but you still need SharePoint installed locally, with great potential for mucking up IIS, and the whole thing feels unwieldy.

  1. Interesting stuff. Another alternative to Subversion that’s rapidly growing is Git and GitHub. Admittedly, it doesn’t seem to be overly popular for .NET developers: “C Sharp is the #12 most popular language on GitHub”.

  2. Just a clarifying note, Dotfuscator in VS2010 does support an “opt-in” mechanism so the end user can control whether the tracking stuff is enabled or not 🙂

    Sinofsky is a good speaker; the question is why present a session on Windows 7 quality at a developer conference keynote, when there is a lot more that should have been said about the developer tools, languages etc. Missed opportunity.

  4. Japan: Let’s name our new games console Wii. What could be wrong with that?
    UK: Kid; I wanna Wii! I wanna Wii now! (Kid, college age).
    UK: Parent; OK! OK! I’m looking for a loo now. (Parent, stuck in hover mode).

    USA: Let’s name our new programming product Microsoft F#. What could be wrong with that?

    USA & UK: Microsoft F***! (College age to 30-somethings mostly).

    Purile, I know, but oh so true. 🙂

    P.S. Like the sound of F#’s functionality, especially from the point of view of the promise of physics programming, assuming it integrates well with the DirectCompute module of DirectX 11’s SDK, amongst other things.
