Hi,

Is the #include wprogram.h within a condition that uses either arduino.h or wprogram.h?

Thanks

The conditional syntax checks the ARDUINO pre-processor definition version. 

It's the #include "arduino.h" that should be valid

Visual Micro should add the ARDUINO version to the  pre-processor section of the C/C++ project options (right click project name in solution explorer and click properties)

If in doubt please save and zip the .vcxproj file and also the [proj_name].vsarduino.h from the __vm folder below the project

email to info[at]visualmicro.com

If the ARDUINO define is missing this suggests some other intellisense issues will also be encountered but as you say it is unrelated to compile.

fyi:

the wprogram.h is no longer used by all recent arduino hardware. some other vendors still use it but normally you can just #include "arduino.h" and remove the conditional #include of wprogram.h

Thanks for the update but it still indicates there is a issue we should look into. The syntax should have worked and shows a problem with an important define.

If possible please zip and email the .vcxproj and vsarduino.h files or attach to a post here. Thanks very much.
