v2rayN Avalonia vs. WPF: UI Frameworks, Supported Platforms & Which Version to Choose

Know the difference between the UI framework, proxy core, and node configuration

WPF is a desktop UI framework for Windows. Avalonia is a cross-platform desktop UI framework that lets v2rayN offer desktop builds for macOS and Linux, among other platforms. Both provide v2rayN’s graphical interface for viewing servers, managing subscriptions, and editing routing rules before passing configuration to the proxy core. Avalonia is not a new proxy protocol, and WPF is not the name of a proxy core.

• Compare the UI: Check menu placement, tray controls, text scaling, window behavior, and OS integration.
• Check the proxy core: Confirm which core is enabled, its version, and whether the build includes the required executable files.
• Check the configuration: Review protocol settings for VMess, VLESS, and other protocols, along with transport, TLS, routing, and DNS.

For example, having a VLESS configuration in your subscription does not mean switching UI versions will fix connection problems. Compatibility depends on whether the proxy core supports the required settings, whether the server configuration matches, and whether all fields were imported correctly. With the same node, core, and routing rules, the UI framework alone cannot tell you which version will be faster.

Choose WPF or Avalonia for your operating system

Start by checking which operating systems are currently listed on the download page. Windows users can choose based on their preferences and available builds. macOS and Linux users should select the Avalonia desktop build for their OS rather than trying to run the WPF package. The recommendation below is for users who want to keep the classic Windows interface; WPF is not the right choice for every device.

If your current WPF build handles subscription updates, routing, and everyday connections, there’s no need to migrate just for the sake of “cross-platform” support. If you’re setting up v2rayN on macOS or Linux, choose the desktop build for that OS and check which features it offers. Don’t expect every menu to have the same name as in Windows screenshots.

Check your system architecture, package type, and runtime dependencies

Choosing the right framework is only the first step. An unsupported OS or processor architecture, or a missing runtime dependency, can prevent the app from starting. Don’t install over your existing setup based only on whether the filename contains v2rayN.

1. Check your system type in Windows: Open Settings → System → About, check System type under Device specifications, then choose an x64 or ARM64 package that’s actually available on the download page.
2. Check your Mac’s chip: Open the Apple menu → About This Mac to see whether your Mac has Apple silicon or an Intel processor, then choose the matching architecture listed on the download page.
3. Check your architecture on Linux: Run the command below. A common output of x86_64 corresponds to x64, while aarch64 corresponds to ARM64. Then choose a package format available for your distribution.
4. Check the dependency notes: Find out whether the package is self-contained or requires a system runtime. Whether you need to install the .NET runtime depends on the package notes and any startup errors—not simply whether it’s called WPF or Avalonia.

uname -m

Linux deb, rpm, and archive packages are not interchangeable. Choose a format supported by your distribution’s package system. With an archive, you may also need to set execute permissions and install dependencies. If macOS shows a security warning, first confirm the package source and compatibility, then follow the standard OS authorization process. Don’t disable system security features altogether.

Migrate subscriptions and routing: keep the configuration source, then recheck system settings

When moving from WPF to Avalonia, or from Windows to another desktop device, start by reusing your subscription URL. A subscription usually distributes node configurations; it does not sync all client preferences. Check the system proxy, listening address, DNS, routing rules, and local file paths individually on the target device.

In the commonly used Chinese-language v2rayN interface, go to Subscription Group → Subscription Group Settings to add the URL, then use the update option in the Subscription Group menu to fetch nodes. Menu names and locations may vary between builds. If you can’t find the exact label, look for the subscription group manager and the update subscription function. Don’t import a subscription URL as if it were a single-node link.

When migrating local routing files, check that their paths are still valid. Windows drive-letter paths won’t work as-is on macOS or Linux, and case-sensitive filenames may affect whether files are found. If you’re restoring a full configuration backup, confirm that the target version supports its format. Don’t force-copy the entire configuration directory to another platform while the app is running.

• Check subscription access: Whether you can use the same URL on multiple devices depends on the subscription provider’s limits.
• Protect your credentials: Before sharing screenshots, hide subscription URLs, UUIDs, passwords, and related keys.
• Test one instance at a time: When switching versions on the same computer, quit the old app first to prevent both instances from competing for a listening port or repeatedly changing the system proxy.

Verify the local listener and system proxy; don’t judge connectivity by the interface

After importing your settings, first confirm that the proxy core starts successfully. Then check whether apps are actually using the local proxy. The example below uses 127.0.0.1:10808 as a local listening address; this is not a claim that every build uses the same default. Check the client settings and logs for the actual address, port, and inbound type.

1. Confirm that the core starts: Check the logs for configuration parsing errors, missing core files, or a port conflict. Fix startup errors before testing web access.
2. Check the inbound type: Confirm whether the port provides SOCKS, HTTP, or a mixed inbound. If you set a proxy manually in an app, its protocol must match the inbound type.
3. Check the system proxy: Set the traffic-handling mode in v2rayN’s system proxy controls, then check the proxy status in your OS. Desktop environments don’t all read system proxy settings the same way.
4. Distinguish routing from traffic handling: The system proxy directs some apps to send requests through the client; routing determines whether those requests go direct or through the proxy. Setting routing to global proxy does not mean every app is using it.
5. Test the app you want to use: First visit a website in a browser that reads the system proxy, then test your target app. If the app has its own proxy settings, configure them separately.

A successful node latency test only shows that the test path received a response. It doesn’t replace testing web access, DNS resolution, or the target app. Differences between Avalonia and WPF interfaces also don’t explain every system proxy issue. If nodes pass latency tests but apps can’t connect, check which apps are covered by the system proxy instead of repeatedly reimporting the subscription.

FAQ: Rule out these issues before switching versions

Keep the selection process simple: choose your OS, match the processor architecture, check package dependencies, then verify the subscription, proxy core, and traffic handling. On Windows, choose based on your interface preferences. On macOS and Linux, select the Avalonia desktop package for your OS. Don’t treat framework names as a speed ranking or overlook each device’s network settings just to keep interfaces consistent.
