What's new since Beta 10.0:

 

→ Powerful Chart Controls (Pro)

  • This new Edition makes the migration even easier by providing the same namespaces, class names, members, events, and visual states as Silverlight (subset)
  • It also makes WPF migration easier because the WPF syntax is closer to Silverlight than UWP (Note: only a subset of WPF is supported at the moment)
  • See also: Editions Comparison and Pricing

 

→ Performance improvement

 

→ New "HtmlPresenter" control to put custom HTML/CSS code in your XAML (Pro)

 

→ Improved support for C# and XAML:

  • Improved the reliability of the "Control.Focus()" method
  • In XAML, ability to set the values of fields in addition to the value of properties
  • Ability to use the {Binding} markup element with fields in addition to properties
  • The Simulator now displays the number of elements at the bottom of the Visual Tree Inspector
  • Improved the appearance of the non-native ComboBox () (Fixed the arrow icon)
  • Support for the scientific notation (such as 1.7E-06) in PathGeometry and Path.Data
  • Improved the rendering accuracy of the control
  • Improved the XAML Inspector (in the Simulator) so that it is possible to enter multiple lines in properties of type "string"

  • Fixed "Array.Empty" compilation error

  • Fixed compilation warning about "GetColumnActualWidth" and "GetRowActualHeight"
  • Fixed an issue where programmatically unchecking a checkbox did not work properly
  • Fixed exception when setting FrameworkElement.MaxWidth and MaxHeight

About C#/XAML for HTML5:

C#/XAML for HTML5 is a free extension for Visual Studio that enables developers to create cross-platform HTML5 apps exclusively using C# and XAML.

It is designed for developers using C#, XAML, and Visual Studio to extend application reach to platforms outside the Microsoft ecosystem, including Android, BlackBerry, Chromebook, iOS, Linux, Mac OS, and web browsers. It can be used to migrate Silverlight apps to HTML5, as well as to create new client-side rich web applications without manipulating HTML, CSS, and JavaScript.

Benefits over alternative cross-platform development tools include zero learning curve for C#/XAML developers, a robust well-organized strongly-typed development experience, the ability to share C# code between the client and the server, and the ability to port legacy apps to the modern web with minimal effort, notably to convert Silverlight apps to HTML.
