CS0012 您必须添加对程序集 Windows、版本 255,255,255,255 Windows 运行时的引用

Question

我正在努力按照帮助on extending my winforms app with UWP

private async void button1_Click(object sender, EventArgs e)
    {
        string str = "WinTreeWUP://";

        Uri uri = new Uri(str);

        var success = await Windows.System.Launcher.LaunchUriAsync(uri);
    }

如屏幕转储所示，我已经添加了文档建议的参考资料。

UWP 应用的最低目标是 Windows 版本 1809 内部版本 17763 我正在使用 VS2017 V15.9.3

完整的错误是

CS0012  C# The type 'IAsyncAction' is defined in an assembly that is not referenced. You must add a reference to assembly 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null, ContentType=WindowsRuntime'.

我在 winforms 项目中使用了以下引用

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.7.2\Facades\System.Runtime.InteropServices.WindowsRuntime.dll
          C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Runtime.WindowsRuntime.dll
    C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Runtime.WindowsRuntime.UI.Xaml.dll

C:\Program Files (x86)\Windows Kits\References.0.17763.0\Windows.Foundation.UniversalApiContract.0.0.0\Windows.Foundation.UniversalApiContract.winmd

Answer 1

我添加了对 C:\Program Files (x86)\Windows Kits\UnionMetadata.0.17763.0\Windows.winmd

的引用

构建不再有问题。
