There is no point in providing a default value for a parameter if callers are required to provide a value for it anyway. Thus, ``++[DefaultParameterValue]++`` should always be used in conjunction with ``++[Optional]++``.


== Noncompliant Code Example

----
public void MyMethod([DefaultParameterValue(5)] int j) //Noncompliant, useless
{
  Console.WriteLine(j);
}
----


== Compliant Solution

----
public void MyMethod(int j = 5)
{
  Console.WriteLine(j);
}
----
or

----
public void MyMethod([DefaultParameterValue(5)][Optional] int j)
{
  Console.WriteLine(j);
}
