Working around the Network Loopback Isolation of UWP Apps
I've been hitting a blockage trying to get my UWP App to receive data from a local UDP port in the following scenario:
- Windows 10 | Version 10.0.16299 Build 16299
- UWP target and minimum Version 10.0.16299
- Declared capabilities :
- Internet (Client & Server)
- Internet (Client)
- UdpClient listening on 127.0.0.1:1234
- Tested on two different systems in different networks with the same resulting behaviour
I am aware of the CheckNetIsolation
tool and already tried the following steps multiple times:
- Ensuring that the App is registered while running with
CheckNetIsolation loopbackexempt -s
- Clearing all exemptions with
CheckNetIsolation loopbackexempt -c
and manually adding the App withCheckNetIsolation loopbackexempt -a -n=*Package Family Name*
- Running the App while all restrictions are cleared with
CheckNetIsolation loopbackexempt -c
I am running my App from Visual Studio, awaiting for UdpClient.ReceiveAsync()
to return something in a while loop.
My code works fine when i use it from a .Net Framework 4.7.2 Console App, so i can exclude any errors interfering on that end.
The only thing that lets me receive data in my UWP App is running CheckNetIsolation loopbackexempt -is -n=*Package Family Name*
. As soon as i stop it from running, my UDP client stops receiving aata.
Sadly, the solution i found and other tools that redirect communication so that they appear to be sent by another source are not possible due to different contraints.
