Getting Started with Cosmos DB + EF Core
summary
Shows how to wire EF Core to Cosmos DB, demonstrates the Azure QuickStart sample, the Cosmos DB emulator and the data migration tool, and walks through configuring container names so EF maps posts, authors and categories into chosen collections. Claims moving from SQL halved monthly cost and allowed tenfold higher ingest; a Redis-to-Cosmos move cut $150 → ~$30. Uses the Cosmos API (DocumentDB), tests locally, and exercises the EF Core provider with polymorphic discriminators and per-entity container mapping.
