What is meant by immutable objects in C#? Is it an instance of a class which has read only properties.

Basically yes.

The String class is a good example of a immutable class. You cannot actually modify the string stored, only create new classes.

Hence the following does not 'modify' the string s, but creates a new variable with the new string containing the old value plus the new value:

s += "World";
