To optimize Regex performance in C#, apply the [GeneratedRegex] attribute to your patterns. This utilizes a Source Generator to compile optimized code at compile-time, significantly reducing runtime overhead during string processing.

The [GeneratedRegex] attribute is a C# feature that triggers a Source Generator to optimize Regex expressions at compile-time, moving the pattern parsing overhead from application runtime to the build phase.

Yes, enforcing the [GeneratedRegex] attribute is specifically designed for high-performance scenarios like data validation and string processing where Regex expressions are frequently used and application performance is critical.

You enforce compile-time optimization by applying the [GeneratedRegex] attribute directly to your Regex pattern definitions within your C# codebase to ensure Source Generator support is utilized.

Yes, enforcing the [GeneratedRegex] attribute requires a C# compiler that explicitly supports Source Generators to successfully generate the compile-time optimized code for your Regex expressions.
