2.3.6 Testing Build

Do not use, this release for internal testing only.

2.3.5-pre5

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.
