Here is what I just did:
deployed this application:
public class Program
public static void Main()
Font font = Resources.GetFont(Resources.FontResources.NinaB);
Bitmap bitmap = new Bitmap(SystemMetrics.ScreenWidth, SystemMetrics.ScreenHeight);
bitmap.DrawText("Hello World", font, Colors.Green, 10, 10);
Opened MFDeploy > Target > Application Deployment > Create Application Deployment
For Deployment File > click Elipses > name the file and save.
For Key: Click Create Key Button, Give the key file a Name, and save it. This will automatically link the key with the Development File.
Hit Ok, wait 10 minutes and you have a generated hex, sig, and key file.
Now erase the board with MFDeploy Select the hex file with the Browse button next to the textbox under Image File and Click Deploy.
I recieved 0 errors with this method, and have a working application on my CWX!
Any other questions let us know!
