It is expected that some methods should be called with caution, but others, such as ``++ToString++``, are expected to "just work". Throwing an exception from such a method is likely to break callers' code unexpectedly.


An issue is raised when an exception is thrown from any of the following: 

* Event accessors
* ``++Object.Equals++``
* ``++IEquatable.Equals++``
* ``++GetHashCode++``
* ``++ToString++``
* ``++static++`` constructors
* ``++IDisposable.Dispose++``
* ``++operator ==, !=, <, >, <=, >=++``
* ``++implicit++`` cast operators


== Noncompliant Code Example

----
public override string ToString()
{
  if (string.IsNullOrEmpty(Name)) 
  {
    throw new ArgumentException("...");  // Noncompliant
  }
  //...
----


== Exceptions

``++System.NotImplementedException++`` and its derivatives are ignored.

``++System.InvalidOperationException++``, ``++System.NotSupportedException++``, and ``++System.ArgumentException++`` and their derivatives are ignored in event accessors.
