How can the error 'A second operation was started on this context instance before a previous operation completed' be resolved when using a wrapper interface?

How can one effectively resolve the error 'A second operation was started on this context instance before a previous operation completed' when using a wrapper interface, ensuring proper management of asynchronous operations, thread safety, and correct usage of the DbContext instance to prevent concurrency issues?

How can the error 'A second operation was started on this context instance before a previous operation completed' be resolved when using a wrapper interface? How can one effectively resolve the error 'A second operation was started on this context instance before a previous operation completed' when using a wrapper interface, ensuring proper management of asynchronous operations, thread safety, and correct usage of the DbContext instance to prevent concurrency issues? The error "A second operation was started on this context instance before a previous operation completed" typically occurs when multiple threads are using the same instance of DbContext concurrently. Here are some steps to effectively resolve this issue:

Ensure Proper Usage of DbContext:

Scoped Lifetime: Register your DbContext with a scoped lifetime in your dependency injection container. This ensures that a new instance of DbContext is created for each request.

Avoid Sharing DbContext Instances: Do not share the same DbContext instance across multiple threads. Each thread should have its own instance3.

Use Asynchronous Operations Correctly:

Await All Asynchronous Calls: Ensure that you await all asynchronous operations. Mixing synchronous and asynchronous calls without proper design can lead to synchronization issues2.

Avoid Blocking Calls: Do not use blocking calls like .Result or .Wait() on asynchronous methods.

Thread Safety:

Thread-Safe Repositories: If you are using repositories, ensure that they are thread-safe and properly manage the DbContext instance.

Concurrency Management: Implement proper concurrency management techniques to handle simultaneous access to the database.
