Microsoft partner Xamarin buys Clarius Consulting's Visual Studio division

Summary: Xamarin's ties to Microsoft are growing ever tighter, thanks to Xamarin's acquisition of the Visual Studio division of Clarius Consulting.


Microsoft development-partner-in-arms Xamarin has acquired the Visual Studio division of Clarius Consulting, giving Xamarin even deeper ties to Microsoft's development suite.


No, there's nothing new to report about previous rumors that Microsoft might be interested in buying Xamarin. It's still a no comment/nothing new to report situation on that front.

But the increasingly tight partnership between Microsoft and Xamarin is likely even tighter after the Clarius deal, given Clarius' expertise and history in developing extensions for Visual Studio. (Microsoft itself is one of Clarius' biggest customers.)

Xamarin and Clarius officials are not disclosing financial terms of the deal. About 10 Clarius employees will be joining Xamarin.

Xamarin officials also announced on May 28 the release of Xamarin 3, the third release of Xamarin's core development platform for building apps for iOS and Android using Microsoft's C#.

Xamarin 3 adds an integrated Xamarin Designer for iOS as an alternative to Apple's Xcode Interface Builder. It also includes a new Xamarin Forms programming interface; support for shared projects for building Universal Windows/Windows Phone apps, as well as for sharing code across iOS, Android and Windows in Xamarin Studio or Visual Studio; built-in support for Portable Class Libraries and NuGet packages; and F# support.

  • And it includes Xamarin Forms

    It comes with XAML and data binding for cross platform development with mapping to native UI controls !!!
    I must try it !!!
  • Hmm

    Could this be a strategy to help Microsoft distance itself from .Net and eventually Visual Studio as a whole as it moves into devices and services? Find various ways to slip money under the table to Xamarin, transfer tech and business relationships bit by bit, and slowly back away before turning its back and running - hard and fast.
    • Look a little closer...

      than just the current headlines, dilettante. Xamarin runs on .Net and builds .Net apps. It runs .Net on iOS and Android. Xamarin is the old Mono .Net and MonoDroid.Net, porting .Net to Linux and Android. That is why the rumors persist that Microsoft will buy Xamarin, as Xamarin helps to further extend .Net to iOS and Android.
  • I bet M$ is pulling the strings

    nothing gets done without the permission of the dark M$ empire, even shuffling dirty money.
    stay away from xamarin as it does not have the seal of approval of the FSF where it fails to pay the dues.

    • No its Google of the 4 horsemen of Apocalypse pulling the strings

      However the strings broke and Google is really mad that they were not able to use C# for .NET instead use a clunky version of Java that runs slower than Xamarin's own C# on its own Android Platform :) :) :)
    • It seems ironic

      that the fsf wants anyone to pay dues. Somehow it seems morally wrong to pay them a penny.
      • freedom is not free

        especially when dealing with the axis of evil software propaganda.
        LlNUX Geek
        • what?

          What propaganda from the evil empire? I didn't see anything from Google or the Linux groups on this... Only stuff about the best programming environment around (Visual Studio).

          Xamarin is far ahead of the Android tools for development. I haven't seen xcode but I'd take a guess that xamarin is ahead there to - and all from being c# based :)
  • hopefully

    If the links keep growing between xamarin and Microsoft hopefully it gets to a point where people with msdn subscriptions could then use the xamarin stuff as part of the subscription.

    In the long run though this is a good move by Microsoft as it provides a way to tap iOS and Android developers to build for the 2 windows platforms as well. Xamarin is doing quite nicely with their ide - its definitely a whole lot better that googles own offerings for developing for android, and has better documentation/help as well. And basing it on c# also would make it easier for developers to cross skill between mobile/windows 8/asp .net(web) programming as well.
