Intellisense errors with VS 16.8.2 / Vm 2020.09.10.08
Nov 29^th, 2020 at 4:07am

After migration to VS 16.8.2 and using VM 2020.09.10.08 existing projects now show a large number of intellisense errors.

for example:

Severity Code Description Project File Line Suppression State
Error (active) E0169 expected a declaration Sannox_TFTtest C:\Repos\Sannox_TFTtest\Sannox_TFTtest\Sannox_TFTtest.ino 181
Error (active) E0020 identifier "millisDelay" is undefined Sannox_TFTtest C:\Repos\Sannox_TFTtest\Sannox_TFTtest\Sannox_TFTtest.ino 40
Error (active) E0020 identifier "millisDelay" is undefined Sannox_TFTtest C:\Repos\Sannox_TFTtest\Sannox_TFTtest\Sannox_TFTtest.ino 41
Error (active) E0020 identifier "millisDelay" is undefined Sannox_TFTtest C:\Repos\Sannox_TFTtest\Sannox_TFTtest\Sannox_TFTtest.ino 42
Error (active) E0020 identifier "DateTime" is undefined Sannox_TFTtest C:\Repos\Sannox_TFTtest\Sannox_TFTtest\Sannox_TFTtest.ino 49

Error (active) E0020 identifier "swdisp" is undefined Sannox_TFTtest C:\Repos\Sannox_TFTtest\Sannox_TFTtest\Sannox_TFTtest.ino 80
Error (active) E0020 identifier "swmode" is undefined Sannox_TFTtest C:\Repos\Sannox_TFTtest\Sannox_TFTtest\Sannox_TFTtest.ino 81

Code complies ok.

an further example

In the ino file the following is used (note: highlighted text shows where the intelliense errors occur:

// use interrupts to handle button presses
attachInterrupt(digitalPinToInterrupt(WIO_KEY_C), disponoff, RISING);
attachInterrupt(digitalPinToInterrupt(WIO_5S_RIGHT), swdisp, RISING);
attachInterrupt(digitalPinToInterrupt(WIO_5S_LEFT), swmode, RISING);

Previous behavior would not throw these intellisense errors.

If the following function prototypes are added under the includes:

void disponoff();
void swdisp();
void swmode();

The intellisense errors no longer appear:

// use interrupts to handle button presses
attachInterrupt(digitalPinToInterrupt(WIO_KEY_C), disponoff, RISING);
attachInterrupt(digitalPinToInterrupt(WIO_5S_RIGHT), swdisp, RISING);
attachInterrupt(digitalPinToInterrupt(WIO_5S_LEFT), swmode, RISING);

Can you confirm if updating to the latest release from the forum link below (20.09.10.16), resolves this issue? https://www.visualmicro.com/forums/YaBB.pl?board=VS_ARDUINO_EXT_RELEASES

Install fails with message: "Exception: This extension is not installable on any currently installed products." (see attached install log).

Note: dev has both VS2019 and Atmel Studio 7 installed but I predominantly use VS2019.

If I right click on the VSIX file only see "Open With>Microsoft VSIX Installer" not "Open With>Visual Studio Version Selector".

Any hints on the issue here.

some success:

The failure to install the 20.09.10.16 release was related to having Atmel Studio 7 installed as well. AS7 had not been updated for some time so it was removed the system rebooted. The VSIX installed ok. VS2019 reported the new version installed.

Checked the code and the same issues present.
Note: the solution/project is split into one ino file and two helpers disphelper cpp/h and nethelper cpp/h.

Some observations:

If a problematic library in the ino file was selected. In a test case millisdelay.h #include line was selected and "Go to document F12" clicked and the erros/highlights are removed. Again the same effect is shown selecting another library.

As soon as the solution is closed and reopened the issues reappear.

This approach does not appear to work on the other files in the solution/project.

Can you confirm there is only one project in the solution? If possible can you email the project to us, and we will be able to investigate further as we are having trouble replicating this at present.

A zip file with the project has been sent via email as requested. Some additional data:

tested with VS 16.8.3 and 2020.09.10.19. Same issue with the test project. Also unable to compile (see note below).
then created a new simple project and this displayed no intellisense errors. Did not compile having issues with finding the correct wire.h ansd spi.h. This ino file when opened in Arduiono 1.8.13 complies ok.
