In Visual Studio have you used tools>options>environment>text editor to set syntax highlight for .ino files?

Is intellisense working when you type code such as "Serial." do you see a list of serial port options such as available()? 

Does this report only apply to .pde/.ino file types?

Which version of Visual Studio?

Thanks

Hi, are you saying that you have cpp files in your arduino project that do not have intellisense or is it just .ino and .pde files you have having a problem with?

Please zip and email the sketch folder so we can see what is wrong.

Thanks

Have you followed this setup guide for Arduino syntax color coding in Visual Studio?

Hi Joe,

I have received your sketch by email and can see that it is an Atmel Studio sketch and not a Visual Studio sketch.

Atmel Studio color coding and intellisense configuration works a different way to Visual Studio and the options shown in the color syntax config guide will not be available. 

There are few ways to fix this problem in Atmel Studio. The quickest solution would be to run the Visual Micro installer and click Uninstall and then click it again to re-install.

You can also run the uninstall via "Windows>add or remove programs>Visual Micro for Arduino". Your Visual Micro personal settings will lost during this process.

Before running this process please close all Atmel Studio instances and then open task manager (right click the window task bar and select Task Manager). In task manager make sure Atmel Studio has shutdown properly, terminate any remaining atmelstudio.exe processes.

If this doesn't fix the problem let me know, I will give you a solution that will fix it.

Thanks

Yes good idea although the title bar of the main ide should say what it is?
