Attributes
| Attribute | Description | Data type | Required | Default value |
|---|---|---|---|---|
| Id | An interface Id (IID). | A GUID in the form xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. | Yes | |
| UseUniversalMarshaler | Set this to true to use the OLE Universal Marshaler as the proxy stub. | An optional boolean value. | No | |
| ProxyStubClsid | Corresponds to the ProxyStubClsid32 registry value. | An optional GUID in the form xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. | No | |
| SynchronousInterface | The Id of another interface registration containing AsynchronousInterface that references this registration. The other interface must be in the same comInterface extension. | An optional GUID in the form xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. | No | |
| AsynchronousInterface | The Id of another interface registration containing SynchronousInterface that references this registration. The other interface must be in the same comInterface extension. | An optional GUID in the form xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. | No |

Remarks
The ProxyStubClsid attribute must reference the Id of a ProxyStub in the same comInterface extension. ProxyStubClsid can only be used for proxy stubs with an implementation as part of the package. To use the OLE Universal Marshaler as the proxy stub, use UseUniversalMarshaler instead.
If UseUniversalMarshaler is true, the Interface registration must include TypeLib.
Note
ProxyStubClsid and UseUniversalMarshaler are mutually exclusive.
