THE OFFICIAL OBFUSCATION PARTNER OF AVALONIA
Avalonia Obfuscator: Code Protection for Avalonia Applications
ByteHide Shield is the obfuscation tool Avalonia officially recommends to protect cross-platform Avalonia apps from decompilation, reverse engineering, and tampering. Enterprise-grade protection for the most starred .NET UI framework.
Free to start. Works with every Avalonia version, every target platform.
Why Avalonia chose ByteHide as its obfuscation partner
An official partnership, not a third-party plugin
"Avalonia has partnered with ByteHide to help developers secure their applications with ByteHide Shield." This is the only quote we use from Avalonia, verbatim from their public announcement. Below: why this partnership matters.
Reason 01
Avalonia is the most starred .NET UI framework
Avalonia has surpassed WPF, MAUI, and every other .NET UI framework on GitHub stars. It is the default choice for developers who want a native-looking, cross-platform desktop and mobile UI written in C#. That reach means your Avalonia application ships to real users on real platforms, and those users can decompile it.
Reason 02
Avalonia evaluated obfuscation, then chose ByteHide
The Avalonia team reviewed the obfuscation options available to their developer community and chose to partner with ByteHide. That partnership is not a referral link. It is a formal, announced recommendation backed by evaluation of the technical fit between Shield and Avalonia's cross-platform model.
Reason 03
Shield ships with first-class Avalonia support
Avalonia's XAML compilation, resource embedding, and cross-platform assembly output all work with Shield out of the box. No workarounds, no exclusion lists to build from scratch. The partnership means Avalonia-specific patterns are treated as first-class inputs to Shield's protection logic.
The partnership announcement is live on the Avalonia blog. The integration is already available in ByteHide Shield today.
What is Avalonia obfuscation and why your app needs it
Cross-platform reach means cross-platform exposure
An Avalonia obfuscator is a tool that protects the C# code and XAML-compiled logic your Avalonia application is built on. Avalonia compiles your code to .NET assemblies that run on Windows, macOS, Linux, iOS, Android, and WebAssembly. Those assemblies can be decompiled to readable C# by anyone with a tool like ILSpy or dnSpy. Obfuscation transforms the names, strings, and control flow in those assemblies so that decompilation produces code that is unreadable and unrecoverable. Your application keeps running correctly on every platform. A reverse engineer, a competitor, or an attacker gets nothing useful.
Avalonia ships your code on every platform
When you publish an Avalonia application, your C# logic and compiled XAML ship inside .NET assemblies that run on every target you support. On desktop platforms, those assemblies are directly accessible on disk. On mobile and WASM, the managed IL still travels with the app. In all cases, the compiled output is far more readable than most developers expect.
Your logic and intellectual property are exposed
Competitors and attackers do not guess how your application works. They open your assembly in ILSpy and read your ViewModels, your business logic, and your UI patterns directly. Proprietary algorithms, licensing implementations, and product differentiators are all visible in the decompiled output without obfuscation.
Secrets in code travel with your app
API keys, licensing validation logic, server endpoint strings, and authentication tokens that live in your Avalonia assemblies ship to every user's device. What feels like private server-side logic is often a string or a conditional in a DLL that anyone can open and read with free tooling.
Unprotected apps can be tampered with
Readable assemblies are patchable assemblies. An attacker who can decompile your Avalonia app can also patch it: bypass licensing checks, remove purchase gates, inject malicious behaviour, and redistribute the modified version. Obfuscation raises the cost of that attack to the point where most attackers stop.
An Avalonia obfuscator is the practical answer to all four risks. Avalonia is built on .NET, so Avalonia obfuscation is .NET obfuscation applied to the way Avalonia ships code across platforms. For the broader .NET context, see our .NET obfuscator guide. Read the .NET obfuscator guide
How to obfuscate an Avalonia application
Three steps from your Avalonia build to a protected release
ByteHide Shield protects your Avalonia application by integrating into your .NET build pipeline. You add the Shield NuGet package to your project, choose a protection level, and build. Shield processes your assemblies automatically as part of the build, so every platform output you produce is protected by default.
Step 01
Add the Shield NuGet package to your Avalonia project
Add ByteHide.Shield to your Avalonia project as a NuGet package. A single command adds it to your .csproj. Shield integrates as a build step, so no separate tool invocation is required. The same package works for every Avalonia target: desktop, mobile, and WebAssembly.
Step 02
Choose a protection level
Set your protection configuration in the ByteHide dashboard or via a shieldproject file checked into your repository. Choose a preset for typical Avalonia applications, or customize individual techniques. Your configuration is stored in your ByteHide account and applied consistently to every build.
Step 03
Build for every platform, protected
Run your Avalonia build as you normally would. Shield runs automatically as a post-compile step and writes protected assemblies in place. Every platform target you produce in the same build, Windows, macOS, Linux, iOS, Android, or WASM, receives the same protection without any extra steps.

What a decompiler sees before and after Shield
Obfuscation is easier to understand when you see it. Here is an Avalonia LicenseService class before and after Shield protects it.
Same behavior, unreadable result. A decompiler now recovers nothing that explains how your licensing logic works or where your keys live.
public class LicenseService
{
private const string ValidLicense = "AVALONIA-LICENSE-2026";
private bool _activated = false;
public bool IsValid(string key)
{
if (string.IsNullOrEmpty(key))
{
return false;
}
if (key == ValidLicense)
{
_activated = true;
return true;
}
return false;
}
}public class _0x3b
{
private bool _0xa1 = false;
public bool _0xf2(string _0x11)
{
int _s = 0;
while (true)
{
switch (_s)
{
case 0:
if (_0x4e.e(_0x11))
{ _s = 0xff; break; }
_s = 1; break;
case 1:
if (_0x11 == _0x12.k(_0xa1))
{ _s = 2; break; }
_s = 3; break;
case 2:
_0xa1 = true; return true;
case 3: return false;
case 0xff: return false;
}
}

What it covers
What ByteHide Shield protects in Avalonia
Shield protects every part of your Avalonia application's .NET code, on every platform you target.
Your code and ViewModels
Shield renames every class, ViewModel, method, field, and parameter in your Avalonia assemblies to meaningless symbols. The application keeps running on every target platform, but a decompiler produces code no human can follow. Control flow obfuscation reshapes the structure further, breaking any analysis that tries to reconstruct what your application does.
Your strings and secrets
String encryption replaces every readable string in your Avalonia assemblies with a runtime decryption call. API keys, server endpoint strings, licensing tokens, and configuration values are hidden from static analysis. The values only exist in memory at the moment they are used.
Your XAML and resources
Compiled XAML, embedded resources, and other content baked into your Avalonia assemblies can be protected and encrypted. Resource protection ensures that even the non-code contents of your assemblies cannot be extracted without the runtime decryption Shield provides.
Your application at runtime
Anti-tamper, anti-debugging, and anti-dump protections defend your application while it runs. If an attacker attaches a debugger to your Avalonia process, modifies your assemblies in memory, or tries to dump them from a running session, Shield detects the attack and responds before any damage is done.
Avalonia obfuscation techniques
Advanced protections, enterprise-grade
Shield applies a full stack of obfuscation techniques to your Avalonia assemblies. Each one closes a path the others leave open. Strong protection comes from layering them, and all of them are designed to work transparently with Avalonia's cross-platform runtime.
Name Obfuscation
Renames all types, ViewModels, methods, fields, and parameters in your Avalonia assemblies to meaningless symbols. Decompiled code becomes unreadable because every identifier, including MVVM class names and binding properties, carries no information.
String Encryption
Encrypts all string literals in your Avalonia assemblies. Readable text constants are replaced with runtime decryption calls so static analysis reveals nothing, including API keys, server endpoints, and license validation values.
Control Flow Obfuscation
Reshapes your method bodies into complex, non-linear control flow that defeats decompilers and makes manual analysis of your application logic extremely slow.
Constants Disintegration
Breaks numeric and boolean constants into computed expressions. Simple values used in your Avalonia application logic are replaced by complex runtime calculations that evaluate to the same result.
Constant Encryption
Encrypts constant values in your Avalonia assemblies so that numeric and boolean literals cannot be recovered through static inspection of the binary, on any target platform.
Dead Code Injection
Inserts meaningless but valid IL code that blends with your real application logic. The extra paths slow down analysis and obscure the actual behavior of your Avalonia ViewModels and services.
Call Hiding
Encodes and hides method references within your Avalonia assemblies. Method calls are indirected so the call graph cannot be reconstructed by a decompiler trying to understand your application structure.
Resource Protection
Encrypts and hides embedded resources so that compiled XAML, configuration data, and other content baked into your Avalonia assemblies cannot be extracted without the runtime decryption layer.
Code Virtualization
Converts critical application methods into custom bytecode run by an embedded VM. The strongest layer available. Apply it to your most sensitive logic: licensing, entitlement checks, business-critical algorithms.
All of these techniques work transparently with Avalonia's cross-platform model. The next section shows which platforms each protection covers.
Compatibility
Cross-platform protection across Windows, macOS, Linux, mobile, and WebAssembly
Avalonia runs on more targets than any other .NET UI framework. Shield protects your assemblies on all of them from the same build step, with no target-specific configuration required.
Windows desktop
Compiled assemblies, embedded resources, compiled XAML.
macOS desktop
Compiled assemblies, embedded resources, compiled XAML.
Linux desktop
Compiled assemblies, embedded resources, compiled XAML.
iOS and Android
Managed .NET assemblies before the platform packaging step.
WebAssembly (browser)
IL assemblies before the WASM compilation, so what reaches the browser is obfuscated.
Shield runs once in your build pipeline and produces protected output for every platform target in the same pass. Switch targets, add targets, or ship to all of them: the protection configuration does not change.
Comparison
ByteHide Shield vs other obfuscation options for Avalonia
Most .NET obfuscation tools are general-purpose standalone tools not built around Avalonia's cross-platform model. ByteHide Shield is the official obfuscation partner of Avalonia and the obfuscation module of a professional application security platform. The comparison below reflects what that difference means in practice.
