Question

How do I store session state in SQL Server for Asp.net mvc4 or Windows Azure Web Role application?

Edit

Why do I get this error?

HTTP Error 500.23 – Internal Server Error

The session state provider is configured in your web.config using the sessionState element. For SQL server you set the mode to SQLServer and configure a connection string. For Azure you could take a look at the following answer which covers different options.
