Handling Soft Deletes in EF Core
When working with business applications, permanently deleting data is often undesirable. Records may need to be restored, audited or retained for compliance purposes. Soft deletes provide a simple solution by marking records as deleted rather than removing them from the database. In this article, we'll explore how to implement soft deletes in Entity Framework Core using query filters and save interception techniques.
Tracking vs No-Tracking Queries Explained
When working with Entity Framework, one of the most overlooked performance considerations is whether queries should be tracked or not. By default, Entity Framework tracks entities returned from queries, allowing changes to be detected and saved automatically. However, tracking comes with overhead and is not always necessary. Understanding when to use tracking and no-tracking queries can improve application performance and reduce memory usage.
Writing Raw SQL When Entity Framework Isn’t Enough
Entity Framework makes database access straightforward, handling most queries with minimal code. However, there are situations where LINQ queries become difficult to optimise, database-specific features are required, or performance is critical. In these cases, writing raw SQL can provide greater control, improved efficiency, and access to capabilities that Entity Framework does not directly support.
Migrations in EF Core Without Breaking Production
Entity Framework Core migrations make database changes manageable, but applying them incorrectly can cause downtime, failed deployments, or data loss in production. This article explores practical strategies for safely managing EF Core migrations, including deployment planning, testing, rollback preparation, and handling schema changes in live environments without disrupting users.
Entity Framework Core Performance Tips
Entity Framework Core is a powerful ORM for .NET developers, but poor query design and inefficient data access can quickly create performance bottlenecks. This article explores practical techniques for improving application speed, reducing database load, and making EF Core applications more scalable and responsive in production environments.
