[UWP]使用CompositionLinearGradientBrush实现渐变画笔并制作动画

1. 什么是 CompositionBrush CompositionBrush(合成画笔)是操作可视化层时用于绘制 SpriteVisual 区域的画笔。 使UWP 应用时可以选择使用 XAML 画笔 或 CompositionBrush(合成画笔) 绘制 UIElement。很多时候XAML画笔和合成画笔都能实现同样的效果，在官方文档 使用 XAML 画笔 vs。CompositionBrush 这一节中有详细的对比介绍。 CompositionBrush性能更好且能做更复杂的动画。XAML Brush的能力是有极限的，我从短暂的UWP生涯当中学到一件事，XAML Brush越是玩弄动画，动画就越可能因为没有料到的事态而失败……除非超越XAML Brush。所以我不做XAML Brush动画啦。 2. 使用CompositionLinearGradientBrush CompositionLinearGradientBrush 是线性渐变画笔，它是最基本的画笔之一，可以实现类似 LinearGradientBrush 的效果。基本使用步骤如下： 通过Compositor创建CompositionLinearGradientBrush； 通过Compositor创建并配置CompositionColorGradientStop

UWP - Headless app stops after 3 or 4 hours

问题 I have a headless UWP app that is supposed to get data from a sensor every 10 minutes and send it to the cloud. When I run the code from the headless app on the Raspberry Pi it stops measuring after 3 or 4 hours, no error (I have a lot of logs). It is exactly 3 or 4 hours. If I start the app at 8, at 11 or 12 it just stops... It looks like it is stopped because I have cancellation token in place that worked well in tests, but here it is not firing anymore. On the App manager in the Device

Using assembly redirection in UWP C#

问题 Hi! I'm getting a typeload exception, the assembly being loaded is targeting runtime version v2.0.50727, other assemblies targets v4.0.30319. I've been reading about Assembly Redirection and I think it could solve this problem but I'm unsure how this would be applied in a UWP app as there is no app.config. Any advice would be helpful!
