Pre-release: Xamarin.Forms 2.3.5.255-pre5

Xamarin.Forms 2.3.5.255-pre5 is now on NuGet. To install the pre-release, check the pre-release option in your NuGet package manager and install this version.

If you have a bug to report, drop us a detailed report here so we can troubleshoot.

Important notes

  • Xamarin.Forms is now compatible with .NET Standard projects! Not all build features may work.
  • Behavior change: Device.RuntimePlatform now returns WinRT on WinRT and UWP on UWP.
  • Behavior change: Using the new AutomationProperties may impact UI Test execution on Android. AutomationId, Name, and HelpText will all set the native ContentDescription property, with Name and/or HelpText taking precedence over AutomationId (Name and HelpText will be concatenated). This means that any tests looking for AutomationId will now fail if Name and/or HelpText are also set on that element. To work around this issue, please alter your UI Tests to look for the value of Name/HelpText in this scenario.
  • Behavior change: Calling Focus on a Picker on WinRT/UWP will now open the drop down.
  • Deprecation: Android IVisualElementRenderer.ViewGroup is now obsolete. Please use View instead.

Important notes

  • .NET Standard: Xamarin.Forms is now compatible with .NET Standard projects! Not all build features may work. We recommend a minimum target version of 1.1. Additional background on Xamarin and .NET Standard is covered on our blog here. Use msbuild when building from the command line.

Service Release: Xamarin.Forms 2.3.4.231

We’ve pushed Xamarin.Forms 2.3.4.231 to NuGet.

Important notes

  • Behavior Change (iOS): ViewDidDisappear may not be reliably called in custom renderers. Please be sure to override Dispose to do any object cleanup that you may be doing in ViewDidDisappear to prevent any possible memory leaks in your custom renderers. (53351)
  • Behavior Change (UWP): Desktop is now a supported Idiom, so your UWP apps will return this value on desktop contexts. Please be aware that Phone will still be returned in continuum scenarios.
  • Behavior Change: Merged ResourceDictionaries will now return a Count that is consistent with the content in the enumeration instead of the total Count of Resources.
  • Breaking Change: Attached Properties are now compiled when XamlC is enabled! If you have XamlC enabled, you must implement a public getter/setter for all attached properties to prevent a compile time error.

2.3.4.231-sr1

  • [2.3.4][Android] OnResume assumed that _application had been set (PR)
  • [Xaml][2.3.4] Do not emit implict_op if from/to are same type (PR)
  • [C][2.3.4] Lookup in RD also lookup in merged RDs (PR)
  • 54334 – “Styles will override properties on UI-Elements when changing resource dictionaries” (PR)

For additional details see the release notes for 2.3.4.224.

Pre-release: Xamarin.Forms 2.3.4.184-pre1

We’ve pushed Xamarin.Forms 2.3.4.184-pre1 to nuget. To install the pre-release, check the pre-release option in your nuget manager and install this version.

If you’ve got a bug to report, drop us a quick report here so we can troubleshoot in detail.

Important notes

  • Xamarin.Forms 2.3.4 depends on a Xamarin installation of Cycle 8. Users upgrading from Xamarin.Forms 2.3.3 (or earlier) will experience numerous compile errors if they attempt to build without first upgrading their Xamarin installation.
  • When upgrading Xamarin.Forms, take care not to simply “update all” as that will update the Xamarin.Android.Support packages to an incompatible version. More info here.
