    <summary>Contains interfaces and classes that define generic collections, which allow users to create strongly typed collections that provide better type safety and performance than non-generic strongly typed collections.</summary>

## Remarks
 Many of the generic collection types are direct analogs of nongeneric types. <xref:System.Collections.Generic.Dictionary%602> is a generic version of <xref:System.Collections.Hashtable>; it uses the generic structure <xref:System.Collections.Generic.KeyValuePair%602> for enumeration instead of <xref:System.Collections.DictionaryEntry>. <xref:System.Collections.Generic.List%601> is a generic version of <xref:System.Collections.ArrayList>. There are generic <xref:System.Collections.Generic.Queue%601> and <xref:System.Collections.Generic.Stack%601> classes that correspond to the nongeneric versions. There are generic and nongeneric versions of <xref:System.Collections.Generic.SortedList%602>. Both versions are hybrids of a dictionary and a list. The <xref:System.Collections.Generic.SortedDictionary%602> generic class is a pure dictionary and has no nongeneric counterpart. The <xref:System.Collections.Generic.LinkedList%601> generic class is a true linked list and has no nongeneric counterpart.
