What is the benefit of using GeneratedRegex over the standard Regex constructor?

GeneratedRegex moves regex compilation from runtime to compile-time. This results in faster first-match performance, reduced memory allocation at runtime, and enables full compatibility with Native AOT (Ahead-of-Time) compilation.

Does this skill help with security concerns like ReDoS?

Yes, the generated patterns include recommendations for setting 'matchTimeoutMilliseconds' to prevent Regular Expression Denial of Service (ReDoS) attacks when processing untrusted input.

What are the requirements for implementing this skill in my C# project?

You must be using .NET 7 or later. Additionally, the class containing the regex and the method itself must be marked with the 'partial' keyword so the Source Generator can inject the implementation.

Can I use this for complex validation in WPF applications?

Yes, this skill includes specific patterns for integrating generated regex with ObservableValidator and MVVM patterns, making it ideal for high-performance WPF data validation.

Developer Tools

Implements high-performance, compile-time regular expressions using the .NET Source Generator to improve execution speed and AOT compatibility.

About

This skill enables Claude to efficiently implement the GeneratedRegexAttribute in .NET applications, shifting regular expression compilation from runtime to build-time. It provides standardized implementation patterns for common validation tasks like email, phone numbers, and URL parsing while ensuring strict adherence to .NET 7+ best practices. By automating the boilerplate of partial classes and static partial methods, this skill helps developers optimize startup performance, reduce memory allocations, and maintain full compatibility with Native AOT deployment scenarios, making it ideal for both high-scale cloud services and responsive desktop applications.

Optimized patterns for email, phone, and URL validation
6 GitHub stars
Configuration support for RegexOptions and security-focused match timeouts
Compile-time regex source generation for .NET 7+
Automatic migration patterns from runtime Regex to Source Generators

Use Cases

Ensuring Native AOT compatibility for regular expression-heavy applications
Implementing performant UI validation in WPF or MAUI desktop apps
Optimizing startup latency and memory usage in .NET microservices
