These are my first experiment with Visual Micro after the installation and registration of the license.
I had some problems with my project, problems not related the Visual Micro, and some visualization problems related the intellisense.
For this reason I have started a new project by selecting the "Blink Led Example" from the projects window.
The build and upload works fine, the led blink
My question is related the intellisense that marks the arduino instructions as unknown.

I have set some settings as explained in the main page of the Visual Micro home page wihtou success.
If I press F12 to go to the definition of the 'pinMode', for example, the VS is able to open the Arduino.h e show the definition of the method.

There are some additional settings to do?

I'm using "Visual Studio 2017 Enterprise", the selected, and used, board is an Arduino Uno and the code is exactly the code created from the 'Projects' page of Visual Studio (Blink Led Example, I have changed only the number of the digital output from 13 to 2 where I have a led).

I'm using the last version of the Arduino IDE (1.8.7)

I'm preparing the email with the output information.

Mail sent.

Thanks

Ok, first of all thanks for the support.
I'm not a c++ developer (I'm C# dev), for this reason I'm not a very expert of the C++

I have created a new VC++ Console Project where I have added an easy method to multiply the argument to 2, and in the main I have called this method and output the value on the console.
The application works and also the IntelliSense.

The version of VS is:

Ok! Now, without change anything, all works fine.
Probably the creation of a 'standard' C++ project has initialized some configuration of Visual Studio and now works fine.

Now I will try with my original project.

Thanks for the support.
