When a reference parameter (keyword ref) is used, the passed argument type must exactly match the reference parameter type. This means
that to be able to pass a derived type, it must be cast and assigned to a variable of the proper type. Use of generic methods eliminates that
cumbersome down casting and should therefore be preferred.
This rule raises an issue when a method contains a ref parameter of type System.Object.
Noncompliant code example
using System;
namespace MyLibrary
{
public class Foo
{
public void Bar(ref object o1, ref object o2) // Noncompliant
{
}
}
}
Compliant solution
using System;
namespace MyLibrary
{
public class Foo
{
public void Bar<T>(ref T ref1, ref T ref2)
{
}
}
}
