Error CS1729 when using NWPath in MAUI iOS project.

Question

Hello,

If I use the NWPath class as new
There is no constructor that specifies 2 arguments (Error CS1729).
Is there any workaround?


<Err Souce code>

public Test(IntPtr handle, bool owns)
{
	NWPath npath = new NWPath(handle, owns) ;	 // Compiler Error CS1729
}


Visual Studio pro 2022
Version:17.7.1
Project:C#

 public NWPath(IntPtr handle, bool owns);

Hello @Mameshiba !

What exactly are you trying to do?

Please note that NWPath is a internal object, and should not be created by the user:
https://learn.microsoft.com/en-us/dotnet/api/networkextension.nwpath.-ctor?view=xamarin-ios-sdk-12

Did you tried to use the MAUI Connectivity class instead?
