Alpha (w/ iOS 9.2 & Xcode 7.2 support) – December 10th, 2015

We are releasing an Alpha preview of our next Service Release to Cycle 6. This is a much bigger service release, and should address a vast majority of the issues we’ve seen reported by the community after the release of Cycle 6. The issues noted below as addressed are not the only ones fixed with this release, so make sure to check out the product release notes to see all the fixes provided with this preview. All fixes included in Service Release 0 are included in this preview, so you should not experience any regression with previous fixes such as Xamarin.VS hanging.

Please use the below forum threads to report and monitor issues that may occur, and find any potential workarounds that may exist.


Known Issues

  • [Xamarin.VS/WatchOS] – WatchKit template sometimes causing failures with Xamarin.VS builds of Watch Apps.
  • [Xamarin.VS] – If the text of the .csproj file does not explicitly include the “IpaIncludeArtwork” property, then the “iOS IPA -> Include Artwork in IPA” property panel will incorrectly show the value as True, when in fact it is False.
    • Workaround: un-check the checkbox and save the project properties, then re-check the checkbox and again save the properties.
  • [Xamarin.VS (36117)] – Certain distribution identities and provisioning profiles do not appear in the iOS project settings. See the bug for possible workarounds.
  • [Xamarin Studio (35977)] – Certain characters (including Japanese and Chinese characters) cannot be typed into the text editor.
  • [Xamarin Studio (34250)] – After certain project operations, all of the menu items in Xamarin Studio will become “disabled” (grey text).
  • [Xamarin.Mac (35851)] – F# projects fail to build due to “The referenced or default base CLI library ‘mscorlib’ is binary-incompatible with the referenced F# core library”.
    • Workaround: Use this build for now. The next full set of Alpha updates should contain this fix.

Products Released

  • Xamarin for Visual Studio 4.0.1.37
    • Release Notes
    • Forum Thread – Alpha Release: Xamarin 4, Cycle 6 – Service Release 1
    • Key Issues Addressed:
      • Fixed the “iOS IPA -> Include Artwork in IPA” checkbox in the project properties so that it correctly saves changes to the value. (Note that one of the remaining known issues is also related to this checkbox. That issue will be fixed in a future build of this service release.)
      • Added a candidate fix for an issue where breakpoints in class libraries were not being resolved (non-public Bug 35691).

Upcoming Release Dates

Stable Release: iOS 9.2 / Xcode 7.2 Support

We are releasing new Stable builds with support for the final iOS 9.2 API that Apple released yesterday as part of Xcode 7.2. Please note this release only supports the iOS 9.2 API, and does not include watchOS2 or tvOS support. Those will come to Stable at a later date (but are available as previews now)

Stable Release: Cycle 6 Service Release 0

We are releasing the earlier preview of our first Service Release to Cycle 6 to the Stable channel. This is smaller release, meant to quickly address some of the most commonly reported issues we’ve seen from the community after the release of Cycle 6.

Please use the below forum threads to report and monitor issues that may occur, and find any potential workarounds that may exist.


Known Issues

**NOTE** – For any hangs observed in Xamarin.VS, please follow the steps here to collect the call stack of the Main Thread. If the call stack does not include “GetAdditionalResourcesFromAssemblies”, please attach it to a new bug report. This will aid us in investigating these fixes, hopefully speeding up the release of patches to address them. 

  • [Xamarin.VS (36185)] – Hang (GUI lockup, freeze) when opening or working on a solution that contains an Android project. Known temporary workaround: delete the hidden .suo file or .vs folder in the solution directory.
  • [Xamarin.VS] – Error ‘Disallowed path(“iTuneMetadata.plist”) found’ on .ipa uploads preventing submission to App Store.

Products Released

  • Xamarin Studio 5.10.1.3
    • Release Notes
    • Forum Thread – Stable Release: Xamarin 4, Cycle 6 – Service Release 0
    • Issues Addressed:
      • Fixed an issue with the iOS Designer where some xib files would not open. (“This File Format is not supported”)
      • Fixed an issue with the iOS Designer where iOS versions 9.0 or higher would throw an exception when translatesAutoresizingMaskIntoConstraints=NO in some widgets. (“One or more errors occurred… at Parse <uknown offset> … at LoadXmlCore <uknown offset>”)
      • Fixed an issue with the iOS Designer where the z-order was not rendering correctly with Storyboards
      • 36189 – Fixed an issue with archiving for publishing generating the wrong value for CloudKit entitlement.
  • Xamarin for Visual Studio 4.0.0.1697
    • Release Notes
    • Forum Thread –Stable Release: Xamarin 4, Cycle 6 – Service Release 0
    • Issues Addressed:
      • 35859 – Fixed an error “vs0192Ø is an invalid ClientId. It must contain only numbers and letters” when attempting to connect to the Mac build host if the Windows user directory contains accented (non-ASCII) characters.
      • 36190 – Fixed an error “Could not write lines to file “obj\Debug\MyLib.csproj.FileListAbsolute.txt”” when building moderately large PCL projects as part of an iOS or Android app.
      • Added an explicit error message “Building from a network share path is not supported at the moment” when attempting to build from an unmapped network share folder on Windows (any path beginning with \\). This is a change to help clarify certain causes of “The “UnpackLibraryResources” task failed unexpectedly”. In its current form, this change will block any attempt to build on a network share that has not been mapped to a drive letter or local folder. This strict rule might be loosened again in the future.

Stable Release: Cycle 6 Final

We are releasing our final Cycle 6 to the Stable channel. These final builds contain all fixes from the previous releases, along with new feature and tons of improvements. Be sure to check out our blog post, and the product release notes below.

If you are used to the updater channels in Xamarin Studio and/or Visual Studio, simply switching to the Stable channel and getting the latest content will give you the final builds. We’ve also updated the standard installers, which will install the builds on your Mac and Windows machine if nothing has been previously installed. (Note – if you have gotten web previews of newer Xamarin Platform builds, the installer will not update and you should use the updater in the IDE against the Stable channel).

Mac Installer  |  Windows Installer

Please note, to use final builds to develop iOS applications in Visual Studio, you’ll need to install them on both your Mac and Windows workstations.

The biggest change with the Cycle 6 builds is an overhaul of how Xamarin builds iOS projects on your Mac from Visual Studio. If you happen to experience issues with any of the products, please log a bug report.


Known Issues

  • Please see product release notes for known issues.

Stable Release: Xamarin.iOS Hotfix for watchOS 1 App Submission

We are releasing new Stable builds to address the issue noted in yesterday’s technical bulletin regarding submissions of watchOS 1 apps built using WatchKit not succeeding. In addition a newer Xamarin.iOS build, we are also providing a new Xamarin.VS build compatible with this updated Xamarin.iOS. The current stable version of Xamarin Studio will work with this updated Xamarin.iOS.

Both of these builds are available through the IDE updater from the Stable channel. For Visual Studio users, please note you will need to update both your Mac Host and your VS environment with the Xamarin.iOS and Xamarin.VS builds respectively.

Watchkit / WatchOS 1 Hotfix Technical Bulletin

We are aware of an issue with our current Xamarin.iOS build that may prevent submission of watchOS 1 apps built using WatchKit. We are working on a hotfix for this issue, and hope to have updated builds for both Xamarin Studio and Visual Studio out later this week.

In the interim, we are making available a preview build of an updated Xamarin.iOS that is compatible with the current Xamarin Studio stable build that should address this issue. This preview is not compatible with Xamarin.VS, but the upcoming Stable hotfix should address this for everyone, including VS users.


Known Issues

[Xamarin.VS / Xamarin.iOS] – watchOS 1 apps built with WatchKit will be rejected during submission with the notification “Invalid WatchKit Support”.
