False Errors (Read 1454 times)

	Hi All I have a VS2017 project which used to be fine and now exhibits false errors, with the below example. My project contains code in a number of .ino files, one of which contains the declaration for a function shown in SS2. The error claims it is incompatible with the declaration at line 356, shown in SS1. Except that SS1 is not a declaration, it's just a use of the function. Curiously, the project compiles without error.... There are similar false errors with use of objects instances. Is there a setting a I can fiddle with? The latest 1906_12 also exhibits this behaviour. The project is for a Teensy.

	Please provide a simple project, just .ino file, with the same issue. Also provide the information shown in yellow at the top of this page and confirm your Teensy version. Thanks

	I tried this again but this time looked for errors in the Errors List. I could see nearly 2000 in VS2017 and 1500 in VS2019. All the false errors related to the underlying core not my own project code. I then click "vMicro>Show Hidden Files" which is recommended for better F12 GoTo Definition anyway. Then the error list reduced to 3 errors without need to filter the Error List for "Open Documents" or "Build Only".

	Thanks for looking at it. I wasn't aware of the show/hide hidden files option. It isn't obvious if it's selected or not. To resolve my issue, I created a new project and then moved things module by module from the old. The application was sufficiently small that I could do this. The new project does not exhibit the same behaviour.

	I see thanks. If you delete the .vs folder below a solution the intellisense database will rebuild next time project is opened. Sometimes that helps VS.
