（NetNative）NetworkInterface.GetNetworkInterfaces（）中的NotImplementedException Win IoT Core 14393

Question

I'm trying to run some code on Windows IoT Core that uses DotNetty and I've run into the following exception:

System.TypeInitializationException: The type initializer for 'DotNetty.Transport.Channels.DefaultChannelId' threw an exception. ---> System.NotImplementedException: The method or operation is not implemented. at System.Net.NetworkInformation.NetNativeNetworkInterface.GetNetworkInterfaces() at DotNetty.Common.Internal.MacAddressUtil.GetBestAvailableMac() at DotNetty.Common.Internal.DefaultPlatform.DotNetty.Common.Internal.IPlatform.GetDefaultDeviceId() at DotNetty.Transport.Channels.DefaultChannelId.DefaultMachineId() at DotNetty.Transport.Channels.DefaultChannelId..cctor() --- End of inner exception stack trace --- at DotNetty.Transport.Channels.AbstractChannel.NewId() at DotNetty.Transport.Channels.AbstractChannel..ctor(IChannel parent) at DotNetty.Transport.Channels.Sockets.AbstractSocketChannel..ctor(IChannel parent, Socket socket)

I have found the issue on github for corefx 9675 and one of the comments says

Those particular methods are unimplemented right now. We plan to add the rest of the support later this year in an update to the System.Net.NetworkInformation package.

I got System.Net.NetworkInformation package v4.3.0 and when I call System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces() directly I sadly get the NotImplementedException exception.

`System.NotImplementedException: The method or operation is not implemented. at System.Net.NetworkInformation.NetNativeNetworkInterface.GetNetworkInterfaces() at System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()

Question

Can I make this work on Windows IoT Core 14393 ?

Answer 1

If you use UWP, you need 10.0.16299.

Because this API(System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()) applies to .NET Standard 2.0 and minimum version support .NET Standard 2.0 is 16299. Also, you need set the UWP app min targeting version to 16299 .

Else, you can use .NET Core Console App or .NET Framework Console App but more versions choices:
