Add support for URL parameters

[NikolaMilosavljevic]

It would be valuable if .NET 5 applications, deployed by ClickOnce, could gain access to URL parameters, specified by the user in the app activation URL.

.NET FX applications could use ApplicationDeployment class to obtain URL parameters: https://docs.microsoft.com/en-us/dotnet/api/system.deployment.application.applicationdeployment.activationuri?view=netframework-4.8

This method is not available to .NET 5 applications as ApplicationDeployment class does not exist.

However, Launcher is a .NET FX application and has access to ActivationUri property.

One solution is for Launcher to obtain URL parameters and persist them to a Json file that would be read by .NET 5 application. This would follow the proposed solution for the similar issue: #27

Any update on this one?
As far as I can see there's literally no way of passing command line arguments to a ClickOnce-deployed .NET 5.0 app at the moment, correct me if I'm wrong?
This is a show-stopper for me porting existing Framework apps to .NET 5.0.

Thank you for your interest in this feature. This is still being tracked for 6.0 milestone. However, we do not have any specific timeline yet.

This also a major issue for us. We deploy our application to hundeds of customers via ClickOnce, but can't move to .NET 5/6 until we have support for URL parameters (as well as some of the missing pieces of System.ApplicationDeployment). By "6.0 milestone", do mean literally by 6.0? Or sometime after the initial 6.0 release?

Unable to port WinForms project from .NET Framework 4.8 to .NET 5.0 due to the following issue:
CS0234 - The type or namespace name 'Deployment' does not exist in the namespace 'System' (are you missing an assembly reference?)

I just wanted to add that I also need this, please add it in a future version!

Parameters must also work on offline intallations (passing them as arguments to the .appref-ms, shortcut in the users start menu).

Porting a brand new application backwards for this missing functionallity... :-(
