[SDKContracts] ApplicationData.Current.LocalFolder

[myokeeh]

I'm trying out Microsoft.Windows.SDK.Contracts v10.0.18362.2002-prevew on a .NET Framework 4.8 Windows Forms app and can't seem to get past this exception for code like below

private async static void Test()
{
        StorageFolder localFolder = ApplicationData.Current.LocalFolder;
        StorageFile sampleFile = await localFolder.GetFileAsync("dataFile.txt");
        IPropertySet values = ApplicationData.Current.LocalSettings.Values;
        //…
}

I've attempted adding System.Runtime, System.Runtime.WindowsRuntime, System.Runtime.WindowsRuntime.UI.Xaml and downgrading specifically to 4.1.2.0

Exception:

Could not load file or assembly 'System.Runtime, Version=4.1.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
