== Why is this an issue?

When a method in a derived class has the same name as a method in the base class but with a signature that only differs by types that are weakly derived (e.g. ``++object++`` vs ``++string++``), the result is that the base method becomes hidden.


=== Noncompliant code example

[source,csharp]
----
using System;

namespace MyLibrary
{
  class Foo
  {
    internal void SomeMethod(string s1, string s2) { }
  }

  class Bar : Foo
  {
    internal void SomeMethod(string s1, object o2) { }  // Noncompliant
  }
}
----


=== Compliant solution

[source,csharp]
----
using System;

namespace MyLibrary
{
  class Foo
  {
    internal void SomeMethod(string s1, string s2) { }
  }

  class Bar : Foo
  {
    internal void SomeOtherMethod(string s1, object o2) { }
  }
}
