• Custom Collections with Non-Integer Indexers cannot be compared.
• When ignoring the collection order, the collection matching spec cannot be a field on a child class. It has to be a property or field of the class.
• The Portable and .NET Standard builds cannot compare private fields or properties on a classs. This is a security restriction by Microsoft.
• ElapsedMilliseconds does not work for Portable and .NET Standard builds as there is no StopWatch in those frameworks.
