Let's identify the real-world problems available with respect to concurrencies, and we will see how we could handle them using the EF Core Framework:

  • In a real-world application, the same data store might be accessed by different modules at the same time. How does EF Core handle those persistences?
    • EF Core has a few concurrency techniques that help us in creating a fail-safe mechanism.
