Remarks
The GetStreamContentType method is called by the data service runtime to retrieve the Content-Type of the media resource that belongs to the specified entity. Use the GetStreamContentType method implementation to set the Content-Type of the media resource. Do not directly set the Content-Type header in your IDataServiceStreamProvider provider implementation.
