Since upgrading from framework to core, i've encountered an unexpected behavior in entity framework core related to the use of .include () and .asnotracking () methods.

Entity Framework And Asnotracking If the entity isn't found in the context, ef core creates a new entity instance and attaches it to the context. query results don't contain any entity which is added to the context but not yet saved to the database. The asnotracking () extension method returns a new query and the returned entities will not be cached by the context (dbcontext or object context). this means that the entity framework does not perform any additional processing or storage of the entities that are returned by the query. When you only need to display data without updating it in entity framework core (ef core), you can significantly improve performance by using the asnotracking method. Unlock the power of entity framework by using asnotracking method when you don't need to track entities to improve performance. learn about untracked entities and why you should do it.

Short answer: no. asnotracking() does not affect the results of count(). the count() method relies on the database to compute the number of matching records. the change tracker (which asnotracking() disables) only affects client side entity management, not the data retrieved from the database. Using .asnotracking() does exactly that. it executes the query and materializes the entities without attaching them to the dbcontext, reducing both the time and memory required for the query. When you're performing read only operations where you don't need to update data, asnotracking() improves performance by skipping the change tracker entirely. while asnotracking() improves performance, it introduces a subtle but important issue: duplicate entity instances. What does tracking changes mean in ef core tracking changes means ef core keeps an entity associated with the current dbcontext and monitors its state over time.
