使 Tizen.TV.UIControls 在 Visual Studio 上工作

Question

我正在开发一个画廊，其中包含来自我托管的网络服务器的图像。问题是我想使用电视控制器（遥控器）在图像之间导航。我尝试了 GitHub 上提供的 Tizen 示例：

https://github.com/Samsung/Tizen.TV.UIControls/wiki/Introducing-Tizen.TV.UIControls https://github.com/Samsung/Tizen.TV.UIControls

但我不能让它们工作。每次我尝试实现它时，我都会收到此错误：

System.TypeLoadException: Could not load type 'Xamarin.Forms.Platform.Tizen.ExportRendererAttribute' from assembly 'Xamarin.Forms.Platform.Tizen, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null'.

   at Gallery.Program.Main(String[] args) in C:\Users\Mow\Source\Repos\ceffDptInfo\tizen_gallery\Gallery.Tizen.TV\Gallery.Tizen.TV.cs:line 18

知道如何让它工作吗？

API 在 Xamarin.forms 4.2.0 上被破坏 https://docs.microsoft.com/en-us/xamarin/xamarin-forms/release-notes/4.2/4.2.0-api#removed-type-xamarinformsplatformtizenexportrendererattribute

在发布新版 Tizen.TV.UIControls 之前，只能在 Xamarin.forms 4.1.x 版本下使用
