Remarks

When programming with .NET, this interface is hidden and developers should use the Nullable<T> class. All Windows Runtime members where the basic IDL signature shows IReference (with a constraint) are instead exposed using the nullable syntax of the nullable value type (for example, ?bool).

When programming with C++/CX, this interface is hidden and developers should use the Platform::IBox<T> interface. All Windows Runtime members where the basic IDL signature shows IReference (with a constraint) are instead exposed using Platform::IBox<T> with the template as a particular value type. This is how C++/CX implements nullable value types. For more info, see Value classes and structs (C++/CX).

Because both .NET and C++/CX have projection equivalents, don't implement this interface unless you are using WRL and/or writing code for a Windows Runtime component and need a nullable value type.

Interface inheritance

IReference; inherits IPropertyValue. Types that implement IReference; also implement the interface members of IPropertyValue.

public : T Value { get; }public T Value { get; }Public ReadOnly Property Value As T// You can use this property in JavaScript.
