"Setting system proxy settings are only supported in Windows" while in Windows MAUI App

Getting "Setting system proxy settings are only supported in Windows. Please manually configure you operating system to use this proxy's port and address." in MAUI (.NET 7) on Windows.

I had the same problem. I am using Titanium from Powershell. After upgrading from Powershell 7.2.7 (.Net 6) to Powershell 7.3 (.NET 7) my script stopped working

For Maui this is because IsRunningAsUwp returns true

MAUI is apparently sandboxe like UWP. If I comment out the check for uwp, maui does set the "registry", sort of. It sets the sandbox register. The maui app is then proxied through titanium but not outside requests (e.g. Chrome). The solution would be to either have a full trust companion (console app) that could adjust the system proxy or if you're just using Maui for the Blazor option then I'd ditch Maui for WPF + Blazor.

If you're interested in getting wpf + blazor to work let me know and I can pass on some additional info.

So, in short, you're saying Titanium Proxy cannot run in MAUI apps on Windows?

It can but you'd have to set the registry values yourself and fork the code to by-pass the UWP check.
