Discover how to work with Entity Framework Core, the popular tool for object-relational mapping (ORM). In this course—the second installment in the Entity Framework Core Essential Training series—learn about persisting data back to the data store, different DbContext options, and how to configure the DbContext. Instructor Phil Japikse covers tracking EntityState, sharing a transaction between two different DbContexts, navigating the batching process, and working with detached entities. He also goes into connection resiliency, how the OnConfiguring method works, how to create a custom execution strategy, and more.
Topics include:
- Persisting data
- Tracking EntityState
- Configuring the DbContext
- Transactions across DbContexts
- Understanding the batching process
- Attaching and deleting detached entities
- Design time configuration
- Concurrency checking
- Using custom execution strategies
