Evolve Keynote Releases!

UPDATE – We’ve added a new build of the Xamarin Profiler that is compatible with the Cycle 7 builds noted below. 

 

As you may have heard from Miguel during the Evolve 2016 Keynote session, we’re releasing a number of new builds to our Alpha and Beta channels, with many new features available to sample right now.

 

 


WEB PREVIEW – XAMARIN WORKBOOKS / INSPECTOR


We are releasing an updated preview of the Xamarin Inspector for iOS, Android, Mac, and WPF applications. Xamarin Inspector is an interactive tool that you can use to diagnose and prototype changes in your application. The inspector can attach to a live application on any of the supported platforms.


Products Released

 

 


WEB PREVIEW – iOS SIMULATOR (FOR WINDOWS)


We are releasing our first preview of the iOS Simulator for Xamarin.VS. The remoted iOS Simulator provides you with a way to test and debug iOS apps on the simulator entirely from Visual Studio on Windows.

 

 


WEB PREVIEW – XAMARIN PROFILER


Xamarin Profiler preview 0.33 is now available for download! There have been a number of fixes since our previous preview, which have been noted below.

Please note that the Mac app bundle has been renamed (from XamarinProfiler.Mac.app to “Xamarin Profiler.app”), so the old version needs to be removed before installing this new update, so that Xamarin Studio prompts the user for the new location.


Products Released

 

 


ALPHA RELEASE – CYCLE 8  FIRST PREVIEW


Our first preview of our newest upcoming feature release (called Cycle 8) can be downloaded from the Alpha channel.

NOTE: Since Google’s newest Android N previews now only allow linking to NDK-provided native libraries, existing apps using e.g. Mono.Data.Sqlite.dll will crash when running on Android N. The functionality to support this is not in this release, however it will be included in a future release of Cycle 8, and will also be published to our Stable Channel via a Service release shortly after Evolve 2016.

NOTE: Visual F# Tools 4.0 RTM must be installed in order for F# console project builds to work with Cycle 8 Xamarin Studio build noted below.

NOTE – You will need to have MS Build Tools 2015 installed in order to use the iOS Designer with the Xamarin.VS build published to the Alpha channel.


Cycle 8 Alpha Known Issues

  • [Xamarin Studio / Xamarin.VS] – Updating your Xamarin.iOS, Xamarin.Android, or Xamarin.Mac to the builds noted below without also updating your IDE will prevent the IDE from properly running license checks, which can cause adverse functionality.
  • [Xamarin Studio – Windows Only] – You must have both MS Build Tools 2013 and MS Build Tools 2015 installed on your machine for Xamarin Studio to work properly on Windows.
  • [Xamarin.iOS] – Breakpoints may not hit for WatchKit applications when the Link All option is selected.
    • Workaround – Perform a “Clean” (or Rebuild) after switching the Link all option on.
  • [Xamarin.Android] – Android.App.Instrumentation subclasses used for app launching or headless execution may not behave as expected when running on API 15 devices or lower.
    • Workaround – Change the target framework for any such project to v2.3.
  • [Xamarin.Android] – Fast deployment is not working correctly for satellite assemblies.
    • Workaround – Disable fastdev/shared runtime to ensure the local assemblies are just bundled into the APK. This does not result in these assemblies also being written into MonoAndroidIntermediateAssetsDir.
  • [Xamarin.Android] – Command line project installation via msbuild/xbuild  (as well as other targets which require a device) will now fail when multiple devices are attached.
    • Workaround – The suggested workflow is to use the ‘serial’ argument: “-s $(serial)”.

Cycle 8 Alpha Products Released

BETA RELEASE – CYCLE 7 RELEASE CANDIDATE


Our next major feature release, called Cycle 7, has had some Alpha and Beta previews out for awhile, but now we’re putting our first Release Candidate to the Beta Channel. We’re really close to finalizing this release, but need your help to hammer on these RCs and shake out any last issues that are hidden away.

NOTE: Since Google’s newest Android N previews now only allow linking to NDK-provided native libraries, existing apps using e.g. Mono.Data.Sqlite.dll will crash when running on Android N. The functionality to support this is not in this release, however it will be included in a future release of Cycle 7, and will also be published to our Stable Channel via a Service release shortly after Evolve 2016.

Preview: Android N Support

We are releasing our first preview with support and bindings for Google’s Android N SDK. Be sure to visit the Android N page and read about all the new features N support provides. If you are looking to get started right away, make sure to check out the new Android N samples and join in on the forum discussions.

Please note that depending on which platform you are targeting, you will need to download certain products for this preview to work:

  • If you are using Visual Studio, you will only need to download the Xamarin.VS linked below.
  • If you are using Xamarin Studio on a Mac machine, you will need to download the Xamarin Studio, Xamarin Android, and Mono Framework linked below.
  • If you are using Xamarin Studio on a Windows machine, you will to download the Xamarin Studio, Xamarin.VS, and GTK Installer linked below.

There is no target stable date for N support at this time, as we have to wait until Google finalizes and publishes their support before we can release ours. That being said, we will do additional N preview releases between now and the final Google release, so be sure to check back and see if newer versions become available in the coming months.

As with all our preview releases, this is not a product we officially support. If you encounter any issues, we recommend filing a bug in Bugzilla. You can also jump into the discussions on the forum thread posted below.


Known Issues 

  • [Xamarin.Studio / Xamarin.VS] – The Xamarin.Android Designer does not support rendering of the new API level (N).
  • 31002 – [Xamarin.Studio / Xamarin.VS] – Users will have to manually make sure their minimum SDK version is set to v6.0 (23) or lower, instead of v6.0.99 (24), in order to deploy to N devices and emulators.
  • 40156 – [Xamarin Android] Projects which utilize Support.v7.AppCompat may no longer compile on Windows when using the preview build tools (24 rc2). This can be worked around by using the latest stable version of build tools instead (23.0.3).
  • 40193 – [Xamarin Android] Certain binding projects may no longer compile on Windows due to generator changes.

Products Released

  • Xamarin for Visual Studio 4.1.0.298 [Download]

Alpha Preview 2: Cycle 7

Update 1 – Bumped Xamarin.iOS from 9.8.0.58 to 9.8.0.156. This adds support for Apple iOS 9.3 / Xcode 7.3. 


We are releasing a new Alpha preview of our next major feature release, called Cycle 7. As this is an Alpha build, there are some known issues and the possibility of new issues being found during testing.

Please check out the product release notes to see all the fixes and known issues for this preview, and use the below forum threads to report and monitor issues that may occur, as well as find any potential workarounds that may exist.


Known Issues

  • [Xamarin Studio w/ F# Add-in] – Error when creating an F# Android template on Windows. This should still function correctly on Mac.
  • [Xamarin Studio] – Dragging and dropping a folder from one project to another moves the files, but does not add them to the destination project.
  • [Xamarin Studio] – Breakpoints are not hitting in Xamarin.Mac C#/F# Unified Applications.
  • [Mono Framework] – Mono 4.3 Cryptography.ProtectedData fails to decrypt data from Mono 4.2. As a result, NuGet packages will fail to restore with the error “Data unprotection failed” when a protected NuGet source is configured.
    • Workaround – In Xamarin Studio you will need to add back any NuGet package sources that use password authentication before re-attempting to restore the packages.
  • [Xamarin.VS & Xamarin.iOS] – When deploying WatchKit applications in Visual studio, the error “The file ‘bin\iPhoneSimulator\Debug\WatchKitApp1WatchKitApp.app\WatchKitApp1WatchKitApp’ does not exist” may appear.

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.

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.
