描述

Description

When building a Windows MAUI app, the NetworkAccess will sometimes return Local for laptop connected via Wifi with Tailscale installed and the Tailscale interface shows up before the wifi Interface in the Control Panel Network Connections screen. I think that the logic may be picking the first connection when you may have more than one connection which is unexpected as Windows itself reports you have internet access but the app thinks you don't.

Steps to Reproduce

It might take a bit of trial and error to reproduce. I was able to disable Tailscale which then returned NetworkAccess.Internet to the app. Now the Tailscale interface is 4th in the list.

研究方向: Investigate the .NET MAUI network connectivity implementation for Windows, specifically the code that selects the primary Internet connection profile. The issue suggests that when multiple network interfaces exist, the first one may be chosen incorrectly. Look for files related to network connectivity in the MAUI repository, such as ConnectivityImplementation.cs or similar. The log shows that GetInternetConnectionProfile() returns the Tailscale profile instead of the WiFi one. Consider whether the code should iterate through all profiles or sort them by priority.
