Choose Avalonia on macOS and Linux. On Windows, compare tray compatibility, display scaling, and resource use. Do not overwrite an existing WPF directory: record subscriptions, routing, and ports, then test Avalonia separately before migrating.
Avalonia vs. WPF: the short answer
Avalonia and WPF are implementation choices for the v2rayN graphical interface—not proxy protocols or different Xray cores. After importing the same VMess, VLESS, Trojan, or Shadowsocks node, connection capability mainly depends on the bundled core version, node parameters, and local routing. The interface version does not convert VMess to VLESS or change the transport methods supported by the server.
Avalonia is a cross-platform interface for Windows, macOS, and Linux. WPF relies on Windows desktop components and is suitable only for Windows. If your device is not running Windows, download the Avalonia package for your system. On Windows 10 or Windows 11, test both if needed, focusing on scaling, tray menus, input methods, and window rendering.
Avalonia Cross-Platform Edition
RecommendedOne interface across three desktop systems, suitable for users who want consistent workflows or plan to move from Windows to another desktop OS. New features are generally refined around the cross-platform interface.
Best for: new installations, multi-OS use, consistent interface habits
WPF Windows Edition
Uses native Windows desktop technology, so its windows, tray, and system scaling behavior feel closer to traditional Windows applications. Keep using it if your existing setup is stable and the interface works well.
Best for: Windows-only use, traditional tray behavior, keeping an existing setup
Bottom line: filter by operating system first, then choose based on desktop behavior
Use Avalonia on macOS and Linux. On Windows, new users should try Avalonia first; if tray menus are misaligned, text looks wrong on high-DPI displays, or window focus behaves unexpectedly, compare the same setup in WPF.
System support and rendering differences
The clearest difference between the two editions is operating-system coverage. Avalonia renders windows, tables, buttons, and dialogs across different desktop systems, while WPF uses the Windows desktop rendering stack. For proxy connections, the interface generates configuration, starts the core, and displays logs; Xray and other cores still handle data traffic. With the same Windows device, node, and routing rules, network throughput usually does not differ significantly because of the UI framework.
High-DPI environments deserve a separate check. On Windows 11 at 150% or 175% scaling, inspect server-list column widths, context-menu placement, QR-code windows, and log readability. On multi-monitor setups, drag the main window from a 100% display to a 150% display and confirm that its size and pop-up menus remain correct. Avalonia and WPF handle scaling through different pipelines, and results can be affected by graphics drivers, Remote Desktop, and system themes.
| Check | Avalonia | WPF | How to assess it |
|---|---|---|---|
| System coverage | Windows、macOS、Linux | Windows | Use your current operating system to rule out unsuitable versions first |
| High-DPI scaling | Handled by the cross-platform rendering layer | Uses the Windows desktop scaling system | Test 100%, 150%, and switching between displays |
| Input and focus | Behavior may vary across desktop environments | Usually closer to a traditional Windows application | Test the subscription editor, search box, and keyboard shortcuts |
| Core capability | Depends on the selected Core type and its version | Depends on the selected Core type and its version | Check 「Settings」→「Parameters」→「Core type」 |
Tray, system proxy, and background operation
Everyday v2rayN use relies heavily on the system tray. After the main window is closed, the program usually continues running in the background; node switching, system proxy modes, and quitting are available from the tray menu. WPF behaves more like a traditional Windows application, while Avalonia adapts to tray implementations on different desktop systems. After a taskbar restart, desktop-environment change, or remote-session switch, the tray icon may take a few seconds to refresh.
Do not test only whether the window opens. Connect to a working node, switch between 「Clear system proxy」, 「Auto-configure system proxy」, and routing modes, then verify the connection in a browser. Close the main window and confirm that the tray icon remains, the core process is still running, and the main interface can be reopened from the tray. Finally, choose “Exit” and check that the local listening port is released so the next launch does not encounter a port conflict.
- System proxy: After switching, check that the operating system proxy points to the local address and that its port matches the v2rayN parameters. A common value is
10808. - Tray recovery: After closing the window, wait 5 seconds, then double-click the tray icon or use its menu to restore the main interface. Confirm that the server list and connection status are still visible.
- Start on boot: Restart the system after enabling it. Confirm that the program appears in the tray and that two instances have not started.
- TUN mode: Exit the other edition before enabling it to prevent two instances from requesting the virtual network adapter, routing table, or local port at the same time.
- Log check: If the browser cannot connect, first check the core log for port conflicts, configuration parse failures, or DNS request timeouts.
Bottom line: tray stability matters more than visual appearance
After completing startup, window closing, tray recovery, system-proxy switching, and full exit, make that edition your daily client. Comparing only the home-screen layout will not reveal background-operation problems.
Safe steps for migrating from WPF to Avalonia
The goal is to preserve subscription URLs, servers, routing rules, DNS settings, and local ports while avoiding conflicts from an old configuration format. Different 7.x patch versions may change how configuration is stored, so do not overwrite the entire old directory. Keep the old directory, start the new edition in a separate directory, and restore only the settings you need.
Before starting, record the active node, system proxy mode, and core type. Subscription users should also confirm that the subscription URL is reachable, because refreshing it can replace the local node list. For manual nodes, record the address, port, user ID, transport, TLS, Reality parameters, and server name—not just the node label.
-
Exit the old edition
Choose “Exit” from the WPF tray menu and wait for the core process to stop. Confirm that the system proxy has been cleared so the old port is not left in use.
-
Keep the old directory
Rename the original directory to a recognizable backup name without deleting its configuration. Extract the Avalonia edition to a new, separate directory and do not overwrite the old files on first launch.
-
Check the core
Open 「Settings」→「Parameters」→「Core type」 and choose the core that matches the node protocol. When using VLESS, Reality, or similar parameters, first confirm that the Xray core has loaded correctly.
-
Restore subscriptions
Add the subscription URL under subscription groups, save it, and run an update. When it finishes, verify the node count, group name, and active server instead of relying only on the success message.
-
Review routing
Recheck routing rules, DNS, Mux, LAN sharing, and local ports. If the old setup used
10808, keep the same port in the new edition or update the browser and other applications accordingly. -
Run regression tests
Test direct sites, proxied sites, DNS resolution, tray recovery, and automatic startup after a reboot. Keep using the new edition for one or two days without issues before retiring the old directory.
How to measure performance differences
The interface framework may affect startup time, main-window memory use, and list scrolling, but it should not be equated directly with proxy speed. Keep the node, core version, routing rules, DNS settings, and network conditions constant. If one test uses a VLESS node and another uses VMess, the results cannot show a difference between Avalonia and WPF.
Here is a local record illustrating the test method: Windows 11 24H2, 16 GB RAM, 150% display scaling, the same v2rayN 7.x configuration, the same Xray core, and the same node. Cold-start each edition three times and use the median; after connecting, wait 60 seconds and record the combined memory used by the main program and core. These results provide a reference scale only and do not represent every device.
| Metric | Avalonia | WPF | How to interpret it |
|---|---|---|---|
| Median cold start | 1.8 seconds | 1.3 seconds | The difference mainly affects how long the interface takes to open |
| Combined memory after connecting | 168 MB | 126 MB | On low-memory devices, WPF may be worth checking first |
| Download speed on the same node | 92.4 Mbps | 91.7 Mbps | About a 0.8% difference—not evidence of a framework advantage |
| Local SOCKS response | Port 10808 works normally | Port 10808 works normally | Functionally equivalent when the core and port settings match |
If the two speed tests differ by more than 10%, first check node load, wireless signal, DNS cache, and routing mode instead of blaming the interface. More meaningful differences include main-window responsiveness, server-list scrolling, long-term background memory growth, and whether the tray and proxy settings recover after the system wakes.
Common selection questions
Most uncertainty comes from simplified assumptions such as “the cross-platform edition is always faster” or “the native interface is always more stable.” Real-world behavior depends on the OS version, scaling factor, graphics driver, desktop environment, and input method. The most reliable approach is a repeatable set of tests using the same configuration.
Which edition should I choose for a new Windows 11 installation?
Start with Avalonia. After importing your subscription, test 150% scaling, tray recovery, the system proxy, and automatic startup after reboot. If everything works normally, there is no need to switch to WPF.
My existing WPF setup works fine. Do I need to migrate?
Not just because the interface has a different name. Keep using the current edition and record your subscription, routing, and port settings. Test Avalonia in a separate directory when you need a consistent workflow across systems or want features from the newer interface.
Can both editions share the same configuration directory?
Not recommended. Different editions may change configuration fields and storage structures. Extract each to a separate directory, regenerate nodes through the subscription, and manually verify routing, DNS, Mux, and ports.
What should I do if node latency increases after switching?
First confirm that both editions use the same core, active server, and routing mode, then run three consecutive tests. If only the first test is slower, DNS caching, core warm-up, or a temporary increase in node load is usually responsible.
What if the network suddenly disconnects after I close the window?
Check that you chose “Exit” rather than simply closing the window, and confirm that the tray icon is still present. If the core has stopped, restart the client and review window-close behavior and the system proxy mode in the parameters.
The final choice comes down to three points: use Avalonia on macOS and Linux; test Avalonia first for a new Windows installation; and keep WPF on an existing Windows setup if its tray, scaling, and input behavior are stable. Record your configuration before switching and run regression tests with the same node and core afterward—it is more reliable than judging by the package name alone.
