WebApi will be able to deserialize your Credential object provided the JSON object has the same field names (I am not sure about case so you may be right here). You seem to be missing the headers from the post call in your Angular2 component.

Can you check the Content-Type using Chrome Debugger or Fiddler? It should be application/json.
