Sample usage:

            //Creating instances
            PortableDevice tablet;
            PortableDeviceCollection devices = new PortableDeviceCollection();
            devices.Refresh();
			
            //Connect to MTP devices and pick up the first one
            tablet = devices.First();
            tablet.Connect();

            //Getting root directory
            var root = tablet.GetContents();

	    //Finding neccessary folder inside the root
            var folder = (root.Files.FirstOrDefault() as PortableDeviceFolder).
                Files.FirstOrDefault(x => x.Name == "Folder") as PortableDeviceFolder;

            //Finding file inside the folder
            var file = (folder as PortableDeviceFolder)?.Files?.FirstOrDefault(x => x.Name == "File");

            //Deleting file device-side
            tablet.DeleteFile(file as PortableDeviceFile);

            //Transfering file into byte array
            var fileIntoByteArr = tablet.DownloadFileToStream(file as PortableDeviceFile);

            //Transfering file into file system
            tablet.DownloadFile(file as PortableDeviceFile, "\\LOCALPATH");

            //Transfering file from file system into device folder
            tablet.TransferFileToDevice("\\LOCALPATH", folder.Id);

            //Creating folder device-side
            tablet.CreateFolder("FOLDER NAME", folder.Id);
        
            //Deleting folder device-side
            tablet.DeleteFolder(folder);
			
            //Close the connection
            tablet.Disconnect();
