In some MVC Examples(Code First Approach), during defining the class for Databace, I found the statement like as
"Public Virtual <classname> Identifier{get;set;}", or "Public Virtual ICollection<classname> Identifier{get;set;}".
Can any one tell me the exact use of using such kind of statements with Virtual Keyword..
Declaring a property or method as virtual means that derived classes can override that property or method. This is particularly useful when using a proxy pattern which some ORMs use in implementing lazy loading (for example, nHibernate). As such, when using
such technologies, it becomes necessary to mark those properties as virtual. [In c# things are not virtual unless explicitly mentioned, unlike in Java]

Use of Virtual Keyword in defining the Class

Hi all,
In some MVC Examples(Code First Approach), during defining the class for Databace, I found the statement like as
"Public Virtual <classname> Identifier{get;set;}", or "Public Virtual ICollection<classname> Identifier{get;set;}".
Can any one tell me the exact use of using such kind of statements with Virtual Keyword..

Thanks in advance...

If a method is declared virtual in a base class, classes that inherits from this base class can override the method.
