errors shown in VisualStudio that are not in my code when using ESP8266 (Read 1830 times)

	Hi, I've been using Visual Micro for a while to code for Arduinos. Now I'm moving to ESP8266 modules for my projects. I have installed ESP8266 Core 2.4.2 (from the Arduino IDE). I'm seeing errors being displayed n the Visual Studio error list that are not from my code but seem to be from ESP8266 libraries / code files. I can still compile and upload without problems, but these errors are a bit annoying (in the way of seeing my own errors) and they also seem to throw off Intellisense. I have attached a screenshot showing these errors. Any idea how I can get rid of them? I'm hesitant to just go and "correct" them. They seem to be in lower level code that I don't really understand. Visual Studio 2017 Community Visual Micro 1807.8.0 ESP8266 2.4.2 Arduino IDE 1.8.4

	Hi, VS intellisense isn't perfect and struggles with some gcc syntax. If you change the combo box from "Build + Intellisense" to "Build Only" then you will see a accurate list after each build.

	Hmmm, this is a bit disappointing. Setting it to "Build Only" means I don't see errors as I type. Isn't there a way to "teach" Intellisense this syntax? Also, when I code in C# in the same Visual Studio I can rename a variable and VS offers me to rename that variable in the whole project. I don't see that option offered when coding for Arduino / ESP8266 with Visual Micro. Is this intentional?

	Any reason why you have not used the other combo box to set the errors list to your project code only?

	OK, "Current Project" still shows these errors but with "Current Document" it works. Not ideal when using multiple files in a project but good enough. Thanks!!
