== Why is this an issue?

Adding https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/params[params] to a method override has no effect. The compiler accepts it, but the callers won't be able to benefit from the added modifier.

=== Noncompliant code example

[source,csharp,diff-id=1,diff-type=noncompliant]
----
class Base
{
  public virtual void Method(int[] numbers)
  {
    ...
  }
}
class Derived : Base
{
  public override void Method(params int[] numbers) // Noncompliant, method can't be called with params syntax.
  {
    ...
  }
}
----

=== Compliant solution

[source,csharp,diff-id=1,diff-type=compliant]
----
class Base
{
  public virtual void Method(int[] numbers)
  {
    ...
  }
}
class Derived : Base
{
  public override void Method(int[] numbers)
  {
    ...
  }
}
