Hallo Tinkerforge Community.   
ich hab ein kleines Problem bei meiner Form. 
Sobald ich in meiner Form auf meinen Backlight Button drücke kommt folgende Fehlermeldung:   
Could not load type 'Tinkerforge.IPConnection' from assembly 'Tinkerforge, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

using Tinkerforge;
namespace Tinkerforge
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [sTAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1()); //hier kommt der FEHLER
        }
    }
}
     
ButtonCode 
         private void button2_Click(object sender, EventArgs e)
        {
            
            IPConnection ipcon = new IPConnection(HOST, PORT); // Create connection to brickd
            BrickletLCD20x4 lcd = new BrickletLCD20x4(UID); // Create device object
            ipcon.AddDevice(lcd);
            if (DisplayOn == false)
            {
                lcd.BacklightOn();
                btnBLOn.Text = "Backlight On";
                DisplayOn = true;
            }
            else
            {
                lcd.BacklightOff();
                btnBLOn.Text = "Backlight Off";
                DisplayOn = false;
            }
            lcd.BacklightOn();
