EntityFramework.VersionedProperties
A library for Entity Framework that automatically maintains an audit history of property-level changes in .NET applications.
Overview
EntityFramework.VersionedProperties is a .NET library that enables fine-grained data versioning at the property level for applications using Entity Framework. It automatically tracks historical changes to individual properties, providing a built-in audit trail without requiring manual implementation.
Key Features
- Property-Level Versioning — Tracks historical changes for individual entity properties, down to primitive types like strings, integers, and dates.
- Built-In Property Types — Includes versioned wrappers for common .NET types such as VersionedString, VersionedDateTime, and VersionedInt32, plus nullable equivalents.
- Custom Type Support — Allows developers to extend versioning to custom complex types through inheritance and interface implementation.
- Trigger Integration — Leverages EntityFramework.Triggers for automatic change tracking and version capture during save operations.
- Automatic History Storage — Persists previous property values in separate version tables each time the current value is updated.
Philosophy
The library aims to simplify audit trail implementation by providing a declarative, property-focused approach that integrates seamlessly with Entity Framework's change tracking and persistence mechanisms.
