Code Analyzer for C#

There is a newer version: 10.2.0.105762

Why is this an issue?
With the advent of .NET framework version 2, certain practices have become obsolete.
In particular, exceptions should now extend System.Exception instead of System.ApplicationException. Similarly, generic
collections should be used instead of the older, non-generic, ones. Finally when creating an XML view, you should not extend
System.Xml.XmlDocument.
This rule raises an issue when an externally visible type extends one of these types:

   System.ApplicationException 
   System.Xml.XmlDocument 
   System.Collections.CollectionBase 
   System.Collections.DictionaryBase 
   System.Collections.Queue 
   System.Collections.ReadOnlyCollectionBase 
   System.Collections.SortedList 
   System.Collections.Stack 

Noncompliant code example
using System;
using System.Collections;

namespace MyLibrary
{
  public class MyCollection : CollectionBase  // Noncompliant
  {
  }
}

Compliant solution
using System;
using System.Collections;

namespace MyLibrary
{
  public class MyCollection : Collection<T>
  {
  }
}
