A step-by-step guide to implementing an audit trail in ASP.NET Core (.NET 5) using Entity Framework Core's ChangeTracker. The approach involves creating an abstract context class that overrides SaveChangesAsync to capture table name, affected columns, primary key, old/new values, operation type, responsible user, and timestamp into an AuditLogs table. The tutorial also covers a bonus tip for more efficient EF Core updates that only persist changed columns, and mentions a NuGet package alternative for modularizing the implementation.
