Been using VMicro on VS2012 for months - love it.

a couple of days ago, was notified of VS upgrade.  accepted upgrade (was for some Java stuff). 

now i get the following in a dialog box whenever i try to open either a new arduino project or any existing arduino project that i had under Visual Micro, which was working just fine.

"Unable to create new sketch
Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index."


also another similar dialog box... 

"OpenProject: Unable to ensure project sketch files: Index was out of range. Must be non-negative and less than the size of the collection. 
Paramter name: index."

my whole environment is broken now and all work has stopped.  

when i try to build the solution here is the exception stack that gets raised.

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
   at System.ThrowHelper.ThrowArgumentOutOfRangeException()
   at System.Collections.Generic.List`1.get_Item(Int32 index)
   at processing.app.SketchEditor.get_SelectedBoard()
   at processing.app.SketchEditor.getBoardPreferences()
   at processing.app.SketchBuilder.get_BuildFolder()
   at processing.app.SketchBuilder.get_BuildPath()
   at Visual.Micro.Visual.Studio.Arduino.AddInApp.CompileDo(Project oProject, Boolean IsDebugStartCommand)
   at Visual.Micro.Visual.Studio.Arduino.AddInApp.OnBeforeCommandEvent(String sGuid, Int32 ID, Object CustomIn, Object CustomOut, Boolean& CancelDefault)


i have uninstalled both the VM addin and the debugger addin and redownloaded/installed same thing. 

help me Obeewankenobee, your my only help!!

pse dont send me back to the Arduino.exe prison !! 

VS2012 still works fine for Win apps.

NEWS FLASH -

the list of arduino boards has disappeared from the "arduino boards" menu in VStudio.  Can this be the cause of the Index error given the exception occurs in at processing.app.SketchEditor.get_SelectedBoard() ???

how do i re-establish the list of avialable boards in VStudio VM Boards pulldown menu ???

i've had this working on 103 and 104 for months - and use the 15x version for the DUE only (and NOT via VMicro).

the tools>options>vm>arduino location has been set since swapped from 103 to the 104 version.  

like i said all was working well, then i get this exception because of the board selection being blank all of a sudden.
If it wasnt for the exception stack dump, i wouldnt have known it was because of the board choices being blanked out/null.

so, now today, without changing a thing, its again working and the dialog box with the boards in it is again populated with boards.  I havent touched configuration of VS at all - just saw the boards again populated and tried it - self fixing code - cool.    Since i can no longer reproduce the problem (which occurred after the VS update from microsoft) i guess we can consider this closed for now.

something was hosed for a days, now its fixed.

i have been working with Visual Studio professionally since it's inception years ago.  You really have a great little product for those of us used to it's environment.  For a casual hobbyist, VS may be a steep learning curve/overkill.

I am now having the same problem as described above.  I'm running VS2012 V11.0.61030 Update4 and I've tried uninstalling and reinstalling both Visual Micro and The Arduino code but still get the same error. 

Any help/suggestions would be greately appreciated

It's an 1.0.x and I installed it at c:\arduino 

I am running the most recent full release of your software. and configured the software location as: C:\arduino\arduino.exe

VS does not list any boards which is part of the problem.  Com port appears to be selectable.   

Thanks, that solves everything.

Task 1 for the day, learn to read instructions fully.
