Hello,

I am just getting started with Arduino and am having some behaviors I don't understand.

I am working in Windows 10, Visual Studio 2015 / Visual Studio Online, Visual Micro 1509.14.0 and Arduino 1.6.5 / Uno.

I created a new project in Visual Studio and included SoftwareSerial.h from the add library menu.  Everything compiled and IntelliSense was working just fine.

After some time and for reasons I don't understand the #include has started telling me it can't find the source file and some words like String are showing as undefined.  When I compare to a new blank/working project the only difference I can see is that the problem project has nothing listed under External Dependencies.

I have started from scratch a few times and have not yet figured out what causes the External Dependencies to all disappear.  No amount of specifying or not specifying paths in the Ide location windows / running rescan / reload tool chains seems to make any difference.

If I toggle Show Arduino Library Sources the External Dependencies populates again but the compile errors do not go away.  When I disable Show Arduino Library Sources then External Dependencies is empty again.

Any ideas what I am doing wrong? 

Thanks,
Shaun

Thanks for the files.

I have to install platform sdk to open your project so that will take a few more days.

One thing that will make it easier for you to move the project to a different future location would be to alter your folder structure slightly. It will also make it easier to check into source control but that might be too late for you

If possible the two projects should be below where the solution (.sln, .vsssc) files are saved.

I create a folder called IoTRoot and moved the two iothome solution files into it. Then put the IoTHome folder and Sensor folder below IoTRoot. Edited the two project paths in iothome.sln to be simpler and shorted "iothome\iothome.vcxproj etc."

If you had that structure then the IotRoot would work on any machine and from any location.

More to follow
