Entity Ftamework how to work with context?

Question

ASP.NET

Hello! How to properly work with the context in EF, create once at application start, or create for each request, and then delete the context? If there are any other better methods, please share? And another question, is it expensive to create a context in terms of performance?

Answer 1

Use DI, caching is used to speed up. Creating a context is not a costly task, because just an object is created, and fetching and connecting to the database occur directly when accessing entities.
