- The default parameter value is assigned at the time of parameter creation.
- Similar to Keep method we have one more method called „Peek“ which is used for the same purpose.
In the Web.config file set sessionState to StateServer for shared in-memory storage or SQLServer for shared durable storage. This is a good approach for applications without specific requirements for a URL scheme. This brings us to the end of this article on MVC Interview Questions.

Q4. What is Razor View Engine? What are the possible file extensions used for razor views?
Each entry in the tree is called a node and is represented by a TreeNode object. A node that contains other nodes is called a parent node. A node that is contained by another node is called a child node. A node that is not contained by any other node but is the ancestor to all the other nodes in the root node. A node can be both a parent and a child, but root, parent, and leaf nodes are mutually exclusive. Several visual and behavioral properties of nodes are determined by whether a node is a root, parent, or leaf node. Caching increases the performance parameter if the same data or information is requested by the user.
It provides a patterns-based way to build dynamic websites that enables a clean separation of concerns.
