CreateStorage() Exception ERROR on Unity5.4(C#)

[takeshi_h_]

Exception ERROR is "EntryPointNotFoundException: PXCMFaceConfiguration_RecognitionConfiguration_CreateStorage"

I have developed on Unity5.4 without unity toolkit , with C# dll for Unity

Face recognition isn't support on Unity ?

I described next two lines like  sdk document

PXCMFaceConfiguration.RecognitionConfiguration rcfg = cfg.QueryRecognition();
rcfg.Enable();

PXCMFaceConfiguration.RecognitionConfiguration.RecognitionStorageDesc desc;

rcfg.CreateStorage("MyDB", out desc);
