Hello,
This issue has been there for years no matter what version of Visual StudioI use.

When I add new library, it is highlighted in red like it is not found.

The code is compiled successfully. But intellisense fails to detect the library members until I close the solution and reopen it after adding the library.

Tried saving all and rebuild. It is the same. It compiles with no error but can not use intellisense like it can not find the library.


This is the current version I use

Thanks. Email was sent.

I have the same issue.

As demo, created new project, and added simple code using SimpleTimer in user libraries.

// Visual Micro is in vMicro>General>Tutorial Mode
//
/*
    Name:       TestApp.ino
    Created:	23/06/2020 14:19:13

*/

#include <SimpleTimer.h>

// the timer object
SimpleTimer timer;

// The setup() function runs once each time the micro-controller starts
// a function to be executed periodically
void repeatMe()
{
    Serial.print("Uptime (s): ");
    Serial.println(millis() / 1000);
}
void setup()
{
    Serial.begin(9600);
    timer.setInterval(1000, repeatMe);
}

void loop()
{
    timer.run();
}
 

Code compiles but SimpleTimer references are highlighted and not known to intellisense.

Unloaded project and reloaded, intellisense now works for these references.

Build logs attached.

Project to follow...

Try closing the solution, delete the ".vs" sub folder below the project then re-open.

Does that work?

Ah sorry I miseread your post. Yes, a build after adding libraries should resolve. We will look into it thanks.

Thanks for all the info. When the intellisense has not refreshed, after adding a libary, please close the solution and zip the .vcxproj file. After re-opening, close the solution again add the vcxproj to another zip or rename and add to same zip.

Then email/attach the zip(s) 

Also confirm, when the libraries have not resolved after compile, does switching to another board on the menu and then back to the same board again, cause libs to resolve?

Thanks

Thanks that is interesting. It might sound lame but Visual Micro isn't doing anything different between adding the library and re-opening the project.

You can see that the .vcxproj is identical between the two operations and has been updated properly with the library path prior to re-open of project. 

Adding the include paths to the vcxproj file is all we have to do to cause VS intellisense to see the library.

Interestingly, what does change between adding the lib and re-opening the project is that the Resharper extension has written its intellisense file. Maybe unhelpfull to say that I uninstalled Resharper a long time ago because it really slowed down my IDE and also Microsoft have improved the C++ refactoring over the past year or so.

Maybe there is a resharper option that tells it to detect changes to project includes as it should be doing.

When time allows we will install resharper to see if we can replicate. Settings vcxproj includes via the VS API is not a complex matter so I fail to understand what we can do different however it will be worth a look.

@Waleed can you confirm that you are also using Resharper (and sorry for the delay with this)?

Thanks

ps: This might actually be a question for resharper. The two rar files show a standard simple vc++ project. Why is a project re-open required after project properties have been set via extension code (as opposed to user manually changing properties via the Project Property Pages)? I believe this is a bug in resharper. Visual Micro does not manage intellisense. Only Resharper and VS does that.

Useful. It must have been a resharper update that has caused the change. 

Please report this to the resharper forum because you have a clear replication simply by unloading and reloading resharper, without making changes to the project.

What would also be interesting to know is:- In a broken state, if you manually add a dummy path to the "project > property pages > C++ > include paths" does that cause resharper to immediately refresh.

Thanks

Yes thanks, as far as I am concerned that is a bug in resharper. Visual Studio and Visual Mico appear to be doing exactly the right things but resharper has stopped working correctly and is blocking intellisense.
