How to get connected Bluetooth device's property in Windows?

Question

I need to get connected Bluetooth device's property in Windows via C#. And I find this post:

Getting a list of already connected bluetooth devices on Windows 10

The code it mentioned is:

//Connected bluetooth devices
DeviceInformationCollection ConnectedBluetoothDevices =
       await DeviceInformation.FindAllAsync(BluetoothDevice.GetDeviceSelectorFromConnectionStatus(BluetoothConnectionStatus.Connected));

But when running the code, I get below exception. It seems that this method cannot be used any more.

Any advise?

The linked answer is almost 5 years old and uses the Universal Windows Platform (UWP).
UWP has been officially deprecated for almost 2 years (and eg. does not support .NET 5 and higher).
Which is why I would not bother trying to get this deprecated approach running (you most probably will run into other problems later - I did when I tried), but look for alternatives instead.
Eg. C# Bluetooth example – searching & listing devices in 2023 (via Google "c# bluetooth devices", limited to results from last year)

Good luck!

Yep this should do it. In the case OP doesn't want to read that article here is the github to the Nuget referenced in the article: https://github.com/inthehand/32feet – Michael Coxon May 03 '23 at 11:34

Might still be usefull.

I got information about connected bluetooth devices using this package and following code

public class Bluetooth
    {
        public async Task<BluetoothDeviceInfo[]> GetBluetoothDevices()
        {
            var bluetoothClient = new BluetoothClient();
            var devices = await Task.Run(() => bluetoothClient.DiscoverDevices());
            bluetoothClient.Close();
            return devices;
        }
    }

    public static async void SomeAction()
    {
        var bluetooth = new Bluetooth();
        var ConnectedDevices = await bluetooth.GetBluetoothDevices();
        if (ConnectedDevices != null)
        {
            Console.WriteLine(ConnectedDevices[0].DeviceName);
            Console.WriteLine(ConnectedDevices[0].DeviceAddress);
        }
    }
