What are the different types of Session state managements available with in ASP.NET?

Answer:

ASP.NET provides In-Process and Out-of-Process state management.

In-Process stores the session in memory on the web server.

Out-of-Process Session state management stores data in an external data source. The external data source may be either a SQL Server or a State Server service.

Out-of-Process state management requires that all objects stored in session are serializable.
