This release of Contentful.Codefirst provides a code-first alternative for .NET developers to manage their content infrastructure within the code base, making it easier to unify content models across environments. It solves the challenge of content model changes being overlooked between staging and production environments. The library allows developers to create content types, fields, and references using attributes and configuration objects, providing control over settings and appearances. Validations can be added to properties using validation attributes, and deletions must be done carefully to avoid data loss. The library is independent from the Contentful Migration CLI and can be installed via NuGet. It enables developers to treat their content model as code in .NET, making it easier to manage and maintain their digital experiences.
