System.Runtime.InteropServices.WindowsRuntime Namespace
The System.Runtime.InteropServices.WindowsRuntime namespace contains classes that support interoperation between managed code and the Windows Runtime, and that enable the creation of Windows Runtime types with managed code.
| Class | Description | |
|---|---|---|
![]() | DefaultInterfaceAttribute | Specifies the default interface of a managed Windows Runtime class. |
![]() | DesignerNamespaceResolveEventArgs | This API supports the product infrastructure and is not intended to be used directly from your code. Provides data for the WindowsRuntimeMetadata::DesignerNamespaceResolve event. |
![]() | EventRegistrationTokenTable<T> | Stores mappings between delegates and event tokens, to support the implementation of a Windows Runtime event in managed code. |
![]() | InterfaceImplementedInVersionAttribute | Specifies the version of the target type that first implemented the specified interface. |
![]() | NamespaceResolveEventArgs | Provides data for the WindowsRuntimeMetadata::ReflectionOnlyNamespaceResolve event. |
![]() | ReadOnlyArrayAttribute | When applied to an array parameter in a Windows Runtime component, specifies that the contents of the array that is passed to that parameter are used only for input. The caller expects the array to be unchanged by the call. See the Remarks section for important information about callers that are written using managed code. |
![]() | ReturnValueNameAttribute | Specifies the name of the return value of a method in a Windows Runtime component. |
![]() | WindowsRuntimeMarshal | This API supports the product infrastructure and is not intended to be used directly from your code. Provides helper methods for marshaling data between the .NET Framework and the Windows Runtime. |
![]() | WindowsRuntimeMetadata | Provides an event for resolving reflection-only type requests for types that are provided by Windows Metadata files, and methods for performing the resolution. |
![]() | WriteOnlyArrayAttribute | When applied to an array parameter in a Windows Runtime component, specifies that the contents of an array that is passed to that parameter are used only for output. The caller does not guarantee that the contents are initialized, and the called method should not read the contents. See the Remarks section for important information about callers that are written using managed code. |
| Structure | Description | |
|---|---|---|
![]() | EventRegistrationToken | A token that is returned when an event handler is added to a Windows Runtime event. The token is used to remove the event handler from the event at a later time. |
| Interface | Description | |
|---|---|---|
![]() | IActivationFactory | Enables classes to be activated by the Windows Runtime. |
