	Hello , im trying to run this library: https://github.com/ntruchsess/arduino_uip/issues Using Arduino's default IDE everything compiles fine and uploads. but using visual micro I cannot compile because the IDE is telling me thare is missing source files. i have confirmed that they do exist, and i only have problems with this library.I think the problem is probably the library but i have no idea what is wrong or how to fix it.Is the library missing something? Anyways i did report the problem to the creator but it was not updated in a long time. The problem is in UIPclient.h #import "Client.h" #import "utility/mempool.h" #import "utility/uip.h" UIPserver.h #import "Server.h" #import "UIPClient.h" the error for the above is eg. cannot open source file "(project_dir)/UIPClient.tlh" cannot open source file "(project_dir)/Client.tlh" cannot open source file "(project_dir)/Server.tlh" and in script this function is not working client.println("DATA from Client"); class "UIPClient" has no member "println" here is some screen shots. https://i.imgur.com/WcPgM77.jpg https://i.imgur.com/WcPgM77.jpg https://i.imgur.com/WcPgM77.jpg

	Those look like intellisense errors. Does the project build?

	Yes it does,I didnt even thought to try it. but it builds, uploads and works. Do you know what went wrong with intellisense? because i can work around this but it could get annoying. thank you for your help BTW. edit : i'm using Visual studio 2017 version 15.7.3 Arduino 1.8.5 Visual micro Release 1806.2 Sp1

	Hi, Intellisense in underlying core might never be 100% but your own code should be OK. You can alter the combo box at the top of the errors list to current project or open documents then you should only see errors in your own code. There is another comboxbox on the errors list that limits to build only. After build, newly added library intellisense should be better. Having said that there are a lot of combinations and things we can do to improve many intellisense issues. To investigate them we need to know which board, libs and core you are using. the best way to tell us that is to enable vmicro>compiler>verbose and "show build properties". Then build and email the output to info[at]visualmicro.com along with link to this post.
