What is the use of session in ASP.NET Core?

Session is a feature in ASP.NET Core that enables us to save/store the user data . Session stores the data in the dictionary on the Server and SessionId is used as a key. The SessionId is stored on the client at cookie. The SessionId cookie is sent with every request.

You can use the Session object to store information needed for a particular user session . Variables stored in the Session object are not discarded when the user jumps between pages in the application; instead, these variables persist for the entire user session.

For external applications, you must create a Session object, if you do not have an Entity object . If you want to use the AdminSession object, the same rule applies.

The Session object is used to store information about a user . The information is retained for the duration of the user session. Variables stored in the Session object are not discarded when the user browses from one page to another, they only destroyed when the user abandons the session or the session time out.
