表扬

Latest Community Issues addressed and PRs merged. · Issue #4302 · dotnet/wpf

优化启动性能 使用调用方法代替反射

预计能提升 0.0001 纳秒的启动性能

Calling AppContext.TryGetSwitch without Reflection in LocalAppContext.cs by lindexi · Pull Request #5522 · dotnet/wpf

优化橡皮擦性能

优化橡皮擦百分之二十的性能,通过缓存预先计算提升性能

Using Per-computed bounds in ErasingStroke by lindexi · Pull Request #4111 · dotnet/wpf

XAML 创建对象性能优化

最多可以提升3倍的 XAML 创建对象性能

Add XamlObjectCreationFactory to improve the performance of XAML creation of objects by lindexi · Pull Request #4026 · dotnet/wpf

笔迹性能优化

使用 readonly 方法,可以减少 WPF 方法调用的时候,拷贝结构体,可以提升笔迹的性能

Using readonly struct in WPF Ink module by lindexi · Pull Request #3908 · dotnet/wpf

Replace the Dictionary with HashSet in AppDomainShutdownMonitor

替换字典为 HashSet 用于减少内存和提升一点性能,详细请看性能测试

Replace the Dictionary with HashSet in AppDomainShutdownMonitor by lindexi · Pull Request #3932 · dotnet/wpf

Reduce memory usage by Array.Empty

使用 Array.Empty 可以减少内存分配,和提升创建对象的性能

Reduce memory usage by Array.Empty by lindexi · Pull Request #3085 · dotnet/wpf

使用 Array.Copy 提升 StylusPointCollection 数组拷贝性能

可以提升触摸时的触摸数据转发的性能,只要是碰到触摸,就可以用到此提升

Using Array.Copy to make array copy faster in StylusPointCollection by lindexi · Pull Request #5217 · dotnet/wpf

数组池优化

给 RenderData 使用上数组池,可以让一切元素渲染时,也许可以减少一点点数组申请。此更改不一定都是正向的,因为会让数组池数组耗尽,本更改的释放是不包括 RenderData 释放时的处理

Using ArrayPool in RenderData by lindexi · Pull Request #5392 · dotnet/wpf

基础数学判断性能优化

这是在许多地方都使用的判断值是否比零足够大的数学判断逻辑,原先的判断是先判断大于零再判断不接近零。优化后是通过将原先的数学公式带入零进行简化,从而可以提升性能

Adding GreaterThanZero to DoubleUtil.cs by lindexi · Pull Request #5571 · dotnet/wpf

Remove the unuse code. by lindexi · Pull Request #4010 · dotnet/wpf

给 Style 里面提升几乎可以忽略的性能

修改 MimeObjectFactory 集合容量

在 MimeObjectFactory 类里面将会包含一个默认的集合,但是这个集合给定的容量和实际运行时的容量不符合,默认给的是 5 的容量,但实际运行时给的是 9 个元素,这就意味着需要一次内存申请和拷贝。我就将默认的容量更改了,设置为 9 提升性能

这个更改将会在每次 WPF 启动的时候都会用到,因此本次更改虽然优化量很小,但能影响每次 WPF 应用启动

Fix the MimeObjectFactory field capacity by lindexi · Pull Request #4493 · dotnet/wpf

修复路径包含井号找不到资源

如果放在了路径包含 # 号的文件夹下,那么有些 WPF 资源将会找不到

Fix GetEntryAssemblyLocation Uri by lindexi · Pull Request #4799 · dotnet/wpf

新语法提升系列

使用 pattern matching 提升 TaskExtensions 的性能

Use pattern matching in TaskExtensions by lindexi · Pull Request #4424 · dotnet/wpf

给锁对象标记 readonly 关键词

给锁对象标记 readonly 关键字,可以减少后续编辑代码时的对锁的不安全更改

优化调试

以下是一个没有啥用的更改,在抛出 Win32Exception 时,写入更明确的信息,然而原本的代码就有写入了,因此以下更改是没有用

Add clearer win32 exception information in SplashScreen CreateWindow by lindexi · Pull Request #3923 · dotnet/wpf

单元测试

加上使用 async 的 FileStream 创建 BitmapDecoder 的测试:

Add Test case for create BitmapDecoder with async file stream. by lindexi · Pull Request #14 · dotnet/wpf-test
