[ACCEPTED]-.NET 5.0 Open Select Folder Dialog-winforms

Accepted answer
Score: 15

I didn't realize I needed to edit the .csproj 6 file, nor did I know you could have both 5 WPF and Windows Forms declared at the same 4 time there. I kept thinking I needed to 3 add it as a reference.

Modifying the project 2 file in this way worked and allowed me to 1 declare using System.Windows.Forms; without getting an error.

  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net5.0-windows</TargetFramework>
    <RootNamespace>WpfApp1_5</RootNamespace>
    <UseWPF>true</UseWPF>
    <UseWindowsForms>true</UseWindowsForms>
  </PropertyGroup>
