From my WPF desktop application, I need to list available WiFi access points, and monitor a WiFi connection. Can this API provide the services I need?

Here is the step to use WiFiAdapter in my WPF (WPFCallUWPapi) project. Step 1. install the below package in the WPFCallUWPapi Nuget.[Microsoft.Windows.SDK.Contracts, System.Runtime.WindowsRuntime, System.Runtime.WindowsRuntime.xaml] Step 2. Add the Button to call the API. <Button Content="Call API" Name="Button" Padding="10" HorizontalAlignment="Center" VerticalAlignment="Center" Click="Button_Click"/> the code for Button_Click:(async is necessary): Step 3. Built annd run the WPFCallUWPapi Step 4. If you meet some error related Identity, you can try to create a Windows Application Packaging Project to make an Identity for WPF App. Mine name is WPFCallUWPapi.App , and it's target versions are all 1903. Set WPFCallUWPapi.App as Startup project.

Yes, it can. Windows.Devices.WiFi.WiFiAdapter API is in UWP , from the document we can see that it has DualApiPartition Attribute. APIs that have the DualApiPartition are supported in all desktop apps, including those with package identity and those without package identity. [ Derive from APIs supported in all desktop applications ].

I created a new WPF App (.NET Framework) project, then went to Project - Manage Nuget Packages..., clicked Browse, and installed the latest version of "Microsoft.Windows.SDK.Contracts". Then I added a Button on my app, and added the following click event handler.

private async void Test_WiFiAdapter(object sender, RoutedEventArgs e) { var access = await WiFiAdapter.RequestAccessAsync(); }

When I build the solution, I get the error message:
CS0103 - The name 'WiFiAdapter' does not exist in the current context.

Is there some other reference I need to add? I added a Windows Application Packaging Project, but that didn't help.

I tried other versions of the package, but got the same result. I tried several suggestions from "learn.microsoft.com/en-us/windows/apps/desktop/modernize/desktop-to-uwp-enhance", but still can't get past the "'WiFiAdapter' does not exist" issue.

What am I missing?

Please add the following namespaces for the WiFiAdapter:

using Windows.Devices.Enumeration;
using Windows.Devices.WiFi;

Still something missing. I added the two 'using' statements you suggested, but it didn't help with the "'WiFiAdapter' does not exist" error. The two new lines are causing the error CS0234 "The type or namespace name 'Devices' does not exist in the namespace 'Windows' (are you missing an assembly reference?)" I looked under 'Add Resources' but found nothing that seemed appropriate.

I have zipped up my entire test project solution. But the forum will not let me attach it here. You can download it from:

Can you see what I am missing?

You mixed using of packages.config and PackageReference.PackageReference is for .Net framework WPF project, and packages.config is for .Net Core WPF project. You need do delow steps to run your project:
Step 1: Right click packages.config and select Migrate packages.config to PackageReference, then do like the below picture shown:

Step 2: Add using System; in the MainWindow.xaml.cs
