SDKFromArduino on Visual Studio?

Hi,
Im making an app in Visual studio (win forms) and it communicates with the Arduino over the usb cable. There is one item under Tools/NuGet that looks great, SDKFromArduino contains sources implemented by the Arduino community.

the only link is to this arduino.cc main website, nothing else.

The goal is to find some software add in that communicates with the Arduino properly? when i run that software I want to send or get data from the PC/visual studio app.

Have done this before but its timer driven and can miss bytes in the buffer. Whats a good communication tool for talking to the PC? and has anyone used this add in for VS c#?
thanks
