.NET Regex Source Generator

The regex source generator creates compile-time generated regex implementations that are:

• AOT-compatible: Works with Native AOT and trimming
• Debuggable: Step through the generated matching code
• Performant: No runtime compilation overhead

When to Use

This skill applies when the user:

• Wants to optimize regex performance
• Needs AOT-compatible regex patterns
• Asks about [GeneratedRegex] attribute
• Mentions converting new Regex(...) to source-generated
• Discusses regex compilation or startup performance
