可空逻辑的特性支持，但是这个支持也许会有坑

Replace null comparisons on non-nullable types that now cause compilation errors, due to the .NET SDK update. by ryalanms · Pull Request #3649 · dotnet/wpf

构建优化

尽管官方说不会去做跨平台的时候，但是依然有一部分 MR 是用来适配在其他平台进行构建，但是当前依然无法在 Linux 平台完成整个 WPF 的构建

这是原本的 MIL 层的代码，以及触摸 PenIMC 底层代码

在这两个代码开放之后，我就水了 WPF 触摸底层 PenImc 是如何工作的 和 WPF 从最底层源代码了解 AllowsTransparency 性能差的原因

文档和注释

理论上文档和注释不会影响行为

看起来我的提交里面水的文档和注释最多了

官方的规划

尽管现在 WPF 所有权在 dotnet 基金会下

但是 WPF 还没全准备好接受来自社区的提交代码，只有在单元测试完成之后才敢接受。而 WPF 的单元测试部分是之前已经写好，但是没有开源。这部分单元测试的开源就是最近从 5 月开始做到现在的内容

当前进度会比原计划慢，客观原因相信大家也知道 However, the global COVID-19 pandemic has caused hiring to be slower than usual. 而在 dotnet 5 更新的时候构建部分还没完全跟上，因此暂时私有版本在 2020.11.12 还不能构建到 dotnet 5 版本

后续将会继续做的修坑和优化性能，然后接受来自社区的更改，走开源管理
