Source Generators vs T4 Templates

Developers should learn Source Generators when working on large-scale C# projects that involve repetitive code patterns, such as generating serialization code, implementing design patterns like MVVM, or creating performance-critical applications where runtime reflection is costly meets developers should learn t4 templates when working in . Here's our take.

Source Generators

Nice Pick

Developers should learn Source Generators when working on large-scale C# projects that involve repetitive code patterns, such as generating serialization code, implementing design patterns like MVVM, or creating performance-critical applications where runtime reflection is costly

Pros

• They are particularly useful for reducing manual coding errors, improving maintainability, and enhancing application startup times by moving code generation to compile-time
• Related to: csharp, roslyn

Cons

• Specific tradeoffs depend on your use case

T4 Templates

Developers should learn T4 Templates when working in

Pros

• NET ecosystems, especially with Visual Studio, to automate code generation and reduce manual, error-prone tasks
• Related to: visual-studio, csharp

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Source Generators if: You want they are particularly useful for reducing manual coding errors, improving maintainability, and enhancing application startup times by moving code generation to compile-time and can live with specific tradeoffs depend on your use case.

Use T4 Templates if: You prioritize net ecosystems, especially with visual studio, to automate code generation and reduce manual, error-prone tasks over what Source Generators offers.

The Bottom Line

Source Generators wins

Developers should learn Source Generators when working on large-scale C# projects that involve repetitive code patterns, such as generating serialization code, implementing design patterns like MVVM, or creating performance-critical applications where runtime reflection is costly
