In the earlier version of C# , if you want a read-only property , you would end up having a backing field which is initialized in the constructor.
public class Employee
{
private readonly DateTime _CreatedDate;
public DateTime CreatedDate
{
get
{
return _CreatedDate;
}
}
public Employee()
{
_CreatedDate = DateTime.Now;
}
}
In C# 6.0 , the auto-implemented properties can be used to implement read-only property using the auto-property initializer as shown below.

public class Employee
{
public DateTime CreatedDate { get; } = DateTime.Now;
}
