Arduino in Visual Studio

Visualmicro is a plug-in for working with Arduino in Visual Studio 2010 (in the near future 2008)



Advantages:

Support for intellisense


Support for several projects, sketches in one solution


Many windows with COM ports


Native plug-ins for supporting other platforms.

Disadvantage: the free version of VS Express does not support plugins, so it can only be used in paid versions of Visual Studio.
