dotnet 5的WPF调度程序

Question

我们正在将.net Framework4.7迁移到.net 5。我们正在处理的项目是一个WPF项目，我们需要使用WPF的Dispatcher类。

在.net Framework4.7中，我们包含了using System.Windows.Threading;和参考WindowsBase，但在.net 5中无法做到这一点。

你知道是什么导致了这种奇怪的行为吗？

提前谢谢。

Answer 1

在.NET 5中，System.Windows.Threading.Dispatcher当然是可用的。

如果要创建类库，项目文件应如下所示：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net5.0-windows</TargetFramework>
    <UseWPF>true</UseWPF>
  </PropertyGroup>

</Project>
