Xamarin 3.3

Xamarin 3.3

Xamarin 3.3 is a minor release to support the new Xamarin.iOS and Xamarin.Android releases, and includes minor features and bug fixes.


  • Enable disconnection from a build host. This allows easy switching between multiple instances of Visual Studio that need to interact with a single build host, without requiring IDE restarts.

iOS Designer

  • Views can now be rearranged using the new SendBackward, SendToBack, BringForward and BringToFront commands.
  • Improved the alignment marker logic so that mid/baseline drop areas are preferred over top/bottom/left/right alignment markers
  • Improved handling of UIViewController.LoadView/UIViewController.ViewDidLoad when rendering custom controls.
  • UIButton frames are now updated as expected when changing the type back to 'System'
  • Fixed an issue where some tristate properties would not change out of the 'indeterminate' state.
  • We now support generating [Action] methods with no sender parameter
  • Improved support for Xcode6 and Yosemite. Some crashes caused by Xcode 6 / iOS8 support have been resolved.
  • An exception triggered by selecting a constraint which references a Top or Bottom layout guide has been fixed.
  • Fixed a case where we could generate invalid storyboard files when working with UITextView.
  • Fixed a crash triggered by disabling autolayout under certain circumstances.
  • The iOS Designer was misgenerating partial methods associated with Actions. The bug caused them to semi-randomly appear/disappear from the .designer file.

Known Issues

  • Visual Studio 2013 Update 2 RC is not supported. Please upgrade to Update 2 RTM.


  • Enables and makes visible Publish context command for non Xamarin.iOS projects (if applicable)
  • Ensure Android project can be deployed before debugging
  • Debugger provides no information on exception that occurs when missing a permission (Android)
  • VS crashes when toggling Error / Warning / Message buttons on and off
  • Build error for WindowsPhone application on Xamarin.Forms solution
  • SDK synchronization broken in XamarinVS 3.1 "Unable to connect to server"
  • Unable to run iOS applications through VS, when paired Build Host has Trial account.
  • Do not force VS Standard toolbar visibility.


  • Improves context detection to automatically hide/show Xamarin commands.
  • Cleanup Tools menu by introducing Android and iOS grouping menus
  • Automatically make iOS toolbar visible only while there is at least one open iOS project (unless the user explicitly changes this behavior)
  • Automatically make Android toolbar visible only while there is at least one open Android project (unless the user explicitly changes this behavior)
