在控制台中使用带有UWP参数的ApplicationData

Question

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

Answer 1

@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.

Answer 2

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.
