Visual Micro is a great tool. However, I have a problem. As soon as I try to use the Serial library will not start debbugern / program. In the output it says: Program Started 'nameOfProjekt'. Since it does not happen any more and I get no output.

The code I'm testing is: 
void setup () {
    Serial.begin (9600); 
} 

void loop () {
   Serial.println ("Hello World ..."); 
   delay (1000); // Do not print too fast! 
} 

If I remove the Serial function code, the program runs as normaly but get no output of course.
