The Windows 11 Task Manager is UWP + WinUI2 hosted in a Win32 application via a XAML Island. |

so the performance issues are for winui 2? |

No, WinUI2 is a visual styling library and doesn't have any inherent performance issues. I can't comment on the internals and causes of the poor performance, but it's safe to assume that UWP is not the bottleneck here. |

This isn't true. WinUI 2 is also a controls library. Compare the WinUI 2 Microsoft.UI.Xaml.Controls namespace with Windows.UI.Xaml.Controls. |

TaskManager isn't slow! The linked reddit post seems to mention that the TaskManager is slow to expand sidebar. Reason: So, it isn't slow, but rather an implementation 'defect'. But, I'm also not sure if there's any better solution in this case. A rewrite of whole UI might be the solution, but who knows how much time that would take. |

Describe the bug
This is very unprofessional behavior when you make a UI framework and just straight up ignore all the complaints about performance which is something very critical when you base windows 11 apps off of it!
