The "Microsoft.Build.Tasks.Xaml.PartialClassGenerationTask" task could
not be loaded from the assembly C:\Program Files (x86)\Microsoft
Visual
Studio\2019\Enterprise\MSBuild\Current\Bin\amd64\XamlBuildTask.dll.
Could not load file or assembly ‘file:///C:\Program Files
(x86)\Microsoft Visual
Studio\2019\Enterprise\MSBuild\Current\Bin\amd64\XamlBuildTask.dll‘ or
one of its dependencies. The system cannot find the file specified.
Confirm that the declaration is correct, that the assembly
and all its dependencies are available, and that the task contains a
public class that implements Microsoft.Build.Framework.ITask.

解决方案，请修改Visual Studio安装（使用Visual Studio安装程序），在“单个组件”选项卡中查找“ Windows Workflow Foundation”并选择它。
