New features in version 0.9.90

  • Rewrite the bottom layer of the Borderless style form, use SkiaSharp to draw form elements
  • Removed the 0.8 version of Acrylic style, this style is very buggy in some Win10 versions and Windows 11
  • Integrate the three commonly used resource controllers EmbeddedFile/LocalFile/DataService into NetDimension.NanUI, and there is no need to install the dependencies of these three resource controllers separately.
  • Rewrite the entire JavaScript communication system, simplify the communication method, and increase the operating efficiency
  • Asynchronous JavaScript binding is upgraded to the native Promise method. By generating awaitable objects in the new Promise(result) of JS, it is convenient to use the new keywords async/await in ES6
