== Why is this an issue?

Throwing such general exceptions as ``++Exception++``, ``++SystemException++``, ``++ApplicationException++``, ``++IndexOutOfRangeException++``, ``++NullReferenceException++``, ``++OutOfMemoryException++`` and ``++ExecutionEngineException++`` prevents calling methods from handling true, system-generated exceptions differently than application-generated errors. 

=== Noncompliant code example

[source,csharp]
----
public void DoSomething(object obj)
{
  if (obj == null)
  {
    throw new NullReferenceException("obj");  // Noncompliant
  }
  // ...
}
----

=== Compliant solution

[source,csharp]
----
public void DoSomething(object obj)
{
  if (obj == null)
  {
    throw new ArgumentNullException("obj");
  }
  // ...
}
