Entity Framework Core 2.0 introduces global query filters that can be applied to entities when model is created. It makes it easier to build multi-tenant applications and support soft deleting of entities. This blog post gives deeper overview about how to use global query filters in real-life applications and how to apply global query filters […]

This blog post introduces defensive database context that throws exception when data from other tenants is about to be updated.
