In this video, Nick Chapsas explains how the Facet library provides an alternative to traditional mapping in .NET development, leveraging strongly-typed LINQ projections to improve performance and developer experience.

Enhancing .NET Code: Using Facet Instead of Traditional Mapping

Presenter: Nick Chapsas

Overview

Nick Chapsas introduces Facet, a library designed to replace traditional object mappers in .NET. Facet aims to provide developers with a more effective and performant way to map and project data, leveraging typed LINQ projections without incurring the typical overhead associated with mapping libraries.

Key Points

  • Facet Library: An open source library that utilizes strongly-typed LINQ projections to perform efficient object mapping in .NET applications.
  • Traditional Mapping Challenges: Standard mapping approaches (using libraries or manual code) can add unnecessary complexity and runtime overhead.
  • How Facet Improves the Process:
    • Eliminates the need for boilerplate mapping code.
    • Offers compile-time type checking via LINQ.
    • Enhances performance by leveraging direct projections.
  • GitHub Repository: Facet on GitHub
  • Community Call to Action: Nick encourages developers to star the Facet repository on GitHub if they find the project useful.

Practical Benefits

  • Cleaner Code: Reduces manual mapping code and potential errors.
  • Better Performance: Avoids overhead associated with runtime mapping.
  • Modern Development Approach: Encourages the use of LINQ and modern .NET features.
