I'm using VS 2012 and Arduino 1.0.5 on Windows 8.1.  In project->add/import sketch libraries->core, only a handful of libraries can be found.  I cannot add the Ethernet or SPI libraries.  I've tried refreshing the list and re-installing arduino, but neither seems to work.  Interestingly, the list of libraries available include all the ones I've installed myself, as well as a few of the default libraries, but there are only about a half dozen available in total.

Hi,

Investigated and can't find a problem, all working okay.  It's possible that a library is causing Visual Micro to terminate the loading of libraries due to some exception. 

I will explain the two locations where libraries can exist. Then hopefully you can add user libraries away from the Core and we will see the error more clearly.

When moving libs around clicking the Project?Add/Import sketch library>refresh command will allow you to see when things go wrong and identify the rouge lib. Whenw e find the problem we will fix it in the next release.

The Two Arduino Library Folders

On the "Core" add/import library menu item you should see the list of libraries that are installed with the ArduinoIde in the libraries folder below the arduino exe folder.

On the "User" add/import library menu item you should see the list of libraries that you have installed yourself. In the Arduino Ide this list is the same as the "Contributed" list of libraries. The libraries you install yourself should be placed in the "[sketchbook]\libraries" folder which is normally "[your documents]\arduino" unless you have changed this location in the preferences.

Can you please delete your Arduino Ide install and re-install or at least rename it and install another copy. Then try adding libraries to the sketchbook\libraries folder and not the ide\libraries folder.

EDIT: Changed the post so user can see the answer more clearly. Thanks for the report!

You will see in our docs the current release supports up to Arduino 1.5.3

There is a new beta on codeplex that supports 1.5.5-r2 

https://visualmicro.codeplex.com/releases/view/106554

ps: I am assuming you meant 1.5.5 when you posted your version as 1.0.5? If not we can take another look at the files you sent. Please report status after applying the Visual Micro beta. Thanks

EDIT: Sorry didn't realize that Christian had jumped in with a confusing post. I think he is the one who is using Arduino 1.5.5? rocketeer13@ please let me know if your problem is fixed by the beta and I will re-look at your report if not. Thanks!!
