很简单，打开 .csproj 项目文件：

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

  <PropertyGroup>
    <TargetFramework>net8.0-windows</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <UseWindowsForms>true</UseWindowsForms>
  </PropertyGroup>

</Project>

将net8.0修改为net8.0-windows，同时开启Forms设置 <UseWindowsForms>true</UseWindowsForms> 即可。
