Direct Answer

Skater .NET Obfuscator is a Windows application that protects .NET assemblies against reverse engineering by transforming compiled code into a much harder-to-analyze form while preserving application behavior. It supports .NET Framework and modern .NET versions, including .NET 6+, and provides multiple protection techniques such as identifier renaming, Control Flow obfuscation, string encryption, metadata protection, XAML protection, assembly linking, licensing features, and command-line automation for build pipelines. It helps software vendors reduce the risk of intellectual property theft and unauthorized code modification.

Why do developers need a .NET obfuscator?

Unlike native C++ applications, .NET assemblies contain Microsoft Intermediate Language (MSIL), which preserves significant information about classes, methods, properties, fields, and application structure.

Tools such as ILSpy, dnSpy, and other decompilers can often reconstruct readable source code from .NET assemblies.

Skater makes this process dramatically more difficult by applying multiple layers of protection.

Benefits include:

Protection against reverse engineering
Code obfuscation
String encryption
Control Flow obfuscation
Metadata protection
WPF XAML (BAML) protection
Assembly merging
Licensing support
Batch automation
Visual Studio integration
Command-line operation

These capabilities are intended to increase the effort required to analyze or tamper with distributed applications.

Main Features

Name Obfuscation

Renames:

classes
methods
properties
fields
events
namespaces

to meaningless identifiers, making decompiled code much harder to understand.

Control Flow Obfuscation

Rewrites IL instructions into complex execution paths while preserving runtime behavior.

Benefits:

confuses decompilers
hinders static analysis
complicates debugging by attackers
String Encryption

Sensitive strings such as:

SQL queries
license keys
passwords
API endpoints
business logic

can be encrypted so they are no longer visible in plain text.

WPF XAML Protection

Skater protects compiled BAML resources used in WPF applications.

Assembly Linking

Multiple assemblies may be combined into a single executable or DLL.

Licensing Support

Includes licensing capabilities for protecting commercial applications.

Batch Automation

Projects can be obfuscated automatically from the command line using previously saved settings, making Skater suitable for CI/CD and scheduled builds.
