There is no CollectionContainsConstraint

[manfred-brands]

There is documentation for a CollectionContainsConstraint but no such class consists in the NUnit source code.

The documentation shows examples of code that internally call: new SomeItemsConstraint(new EqualConstraint(expected));
That is mentioned in the Notes section of the article.

The article contents is correct, except for the title and constructor part.
The examples are short cuts to other constraints.
