Remarks

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.
