问题
I'm trying to follow UWP with Desktop Extension – Part 2 of UWP and WinForms desktop-bridge calling the processes and passing parameters. This example Console Program.cs code includes parameters string:
string parameters = ApplicationData.Current.LocalSettings.Values["parameters"] as string;
But the name ApplicationData does not exists in the current context, I'm trying to find out, if I've missed some reference or it is different version of C#
I'm not sure even if it is what it requires, but adding of reference Windows.Foundation.UniversalApiContract.windmd throws another error with Values:
Error CS0012 The type 'IPropertySet' is defined in an assembly that is not referenced. You must add a reference to assembly 'Windows.Foundation.FoundationContract
回答1:
If you want to use ApplicationData class, please add Windows.winmd where in the C:\Program Files (x86)\Windows Kits\10\UnionMetadata\10.0.17134.0\Windows.winmd. Then add Windows.Storage namespace.
Detail steps
Right click project References -> Add References -> Browse(file type all file)-> select Windows.winmd

@Nico Zhu - MSFT is correct, but I would also suggest alternative approach, which may make your life easier in the long run - the UWP APIs for desktop apps are now also distributed via NuGet as a package which takes care of referencing the right libraries for you.
It is in preview at the time of writing, so you can install as follows:
Install-Package Microsoft.Windows.SDK.Contracts -Version 10.0.18362.2002-preview
See the NuGet page for more info.
