How many times have you written the same Where clause in your EF Core queries?

Soft deletes. Multi-tenant filtering. “Only active” records. We copy and paste the same conditions across repositories, services, and controllers — hoping we don’t forget one.

EF Core has a built-in feature that can automatically apply those filters to every query: Global Query Filters.

In this lightning talk, you’ll learn what Global Query Filters are, how to configure them in just a few lines of code, and when they make your codebase dramatically cleaner. We’ll walk through a simple example (soft deletes and tenant isolation), see how the filter is applied automatically, and look at the one thing you must know to avoid surprises.

If you’re using EF Core and repeating filtering logic throughout your application, this talk will give you a simple, practical tool you can use immediately.
