Assembly: Microsoft.VisualStudio.QualityTools.UnitTestFramework (in Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll)
All elements in subset are found in superset and are found in sufficient quantity.
One collection is a subset of another collection if every element in the first collection also appears in the second collection. An element that appears in the first collection more than once must appear in the second collection as many times, or more, as it does in the first collection. The second collection may have elements that are not in the first collection, but that is not required.
