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 with CheckNetIsolation 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.

 

Issues with using Add-AppxProvisionedPackage to provision UWP app

I am currently trying to manage installation a line of business UWP application on a series of client machines. I need to make sure that the application is installed for any user that signs into windows on a particular machine. To do this I am copying the APPX file of the UWP app to a provisioning directory, and using this command to provision the application:

Add-AppxProvisionedPackage -Online -PackagePath C:\myapp-provision -SkipLicense.

The application installs fine for users some/most of the time. However, I am running into a couple of issues fairly consistatnly.

1. Sometimes, after provisioning a new version of the application, when a new user signs into windows, they still see the previous version of the application installed.
   
2. Sometimes, after provisioning the application for the first time, when a new user signs into windows and searches for the app in the start menu, they get no results.
   

Both of these issues can be resolved by going to Apps & Features, searching for the application in list, selecting Advanced Options on the app, and then selecting reset.

This is an ok fix for the short term, but long term, I cant rely on users to always be aware that they may need to reset the app before using it.

Is there a better way I can go about getting this application installed for all users? Are there additional steps I am missing?

 

UWP app live tiles not working

I did what you suggested, but after a while the tiles went to solid colors again.
