Intellisense not including required paths with Teensy 4.0

Using VM22 and visual studio 22 with a Teensy 4.0, intellisense cannot find specific functions or keywords, and underlines them with red squiggles. It appears to not be including some additional paths in the intellisense include directory. This code compiles, links, and runs properly. I have attached the build.txt

Here is the code snippet:
Code (C++)
Select All
#include <functional>

struct Event {
	std::function<void()> callback; //RED SQUIGGLES HERE
	void Fire() { callback(); } //RED SQUIGGLES HERE
};

Event action;

void setup() {
	Serial.begin(115200);
	action.callback = print;
}

void loop() {
	Serial.println("commanding fire");
	action.Fire();
}

void print() {
	Serial.println(" callback fired");
	delay(1000);
}

I suspect this is related to the VC++ intellisense system the current version of Visual Micro uses. Microsoft C++ intellisense doesn't understand some gcc code.

If you download Visual Micro 2.0 and create a new project you should find that things work much better. The 2.0 version of Visual Micro uses the newer Microsoft Linux Workload for intellisense that understand gcc. We have also been able to take full advantage of that by implementing a new core discovery for the intellisense. This gives 99.9% accurate intellisense, a big difference.

You won't see any difference after you install Visual Micro 2.0 unless you delete or move the .vcxproj file from your code folder and then use "File>Open>Arduino Project" so that a new .vcxproj is created for you.

Going forward we won't use the Visual Studio desktop c++ workload. Instead we will only use the Linux Workload.

As you correctly point out, the build system uses the arduino specification and is unlrelated to the intellisense engine.

I hope this makes sense. 

Visual Micro 2.0 RC3 is available from the new releases board of this forum. It will be released to the gallery during the next week. We are currently completing some improvements for Teensy COM port discovery when you have installed the Arduino 2.0 version of Teensy. The version of Teensy you are using with 1x Arduino IDE is the same as the Arduino 2.0 but with com port discovery working. Therefore, don't change your Teensy config for this excercise just update Visual Micro and allow a new project (.vcxproj) to be created for your code. (We will be auto updating older projects in future releases)

Thanks for the detailed response! Unfortunately, there still appear to be a few issues though. 

I downloaded and installed Visual Micro 2.0 RC3, and created a new project from scratch. It appears to not find the ARM and ARM64 references in the .vcxproj.

Quote:
error : Designtime build failed for project 'C:\Users\Mike\Documents\Git\Arduino\TestProject\TestProject.vcxproj' configuration 'Debug|ARM'. IntelliSense might be unavailable.
     Set environment variable TRACEDESIGNTIME = true and restart Visual Studio to investigate.


Thank you for the help!

Hi, did it prompt you to install the Linux Workload? If not then it can be install via "Tools>Get Tools"
