It should be mentioned somewhere in the documentation, that this method does work as designed. However, an attempt to re-deploy the source code without power cycling the Display will fail.

In order to re-deploy the same code, a power cycle is required to set the baud rate back to the default.

In my case power cycling was not required. If you re-deploy code without Display power cycling the temporary baud rate change command will fail but after that other commands should succeed. Do you have other experiences?

No, on my end it fails and the rest of the code also fails.

Can you try this code:
            var port = NextionDisplay.TemporaryChangeBaudRate("COM2", 9600, 115200);
            var display = new NextionDisplay(port);
            display.GUI.WriteText("Test " + DateTime.Now.ToString(), 0, 0, 200, 50, 0, (int)Color.Green, (int)Color.Transparent, HorizontalAlignment.Left, VerticalAlignment.Center);

On my device it is working (date and time is refreshing) every two seconds.
