== Why is this an issue?

Method for creating empty arrays ``++Array.Empty<TElement>()++`` was introduced in .NET 4.6 to optimize object instantiation and memory allocation. It also improves code readability by making developer's intent more explicit. This new method should be preferred over empty array declaration.


=== Noncompliant code example

[source,csharp]
----
public void Method()
{
    var zero_length = new int[0]; // Noncompliant
    var empty_array = new string[] { }; // Noncompliant
}
----

=== Compliant solution

[source,csharp]
----
public void Method()
{
    var zero_length = Array.Empty<int>();
    var empty_array = Array.Empty<string>();
}
----
