 ## -remarks
 
 When programming with .NET, this interface is hidden and developers should use the [System.Collections.Generic.KeyValuePair&lt;TKey,TValue&gt;](/dotnet/api/system.collections.generic.keyvaluepair-2?view=dotnet-uwp-10.0&preserve-view=true) structure. In any case where a Windows Runtime type has implemented IKeyValuePair&lt;K,V&gt;, including when interfaces have inherited IKeyValuePair&lt;K,V&gt; or used it as an inner constraint, .NET code can treat it as a .NET [KeyValuePair](/dotnet/api/system.collections.generic.keyvaluepair-2?view=dotnet-uwp-10.0&preserve-view=true).
 
-Key-value pairs are used in the [IMap<K,V>](imap_2.md) interface, when it inherits [IIterable<T>](iiterable_1.md). Practical implementations of [IMap<K,V>](imap_2.md) are iterable, and iterating or calling [First](iiterable_1_first_1920739956.md)/[Current](iiterator_1_current.md) explicitly will return instances of IKeyValuePair&lt;K,V&gt; using the same constraints as does the [IMap<K,V>](imap_2.md) implementation.
