One cool package for playing around with your phidget(s) is `mono-csharp-shell` which gives you an interactive C# shell (with tab completion).
apt-get install -y mono-csharp-shell
Once the package is installed, you can open it with `csharp` but just like with `gmcs` we have to include the reference to the Phidget library.
It will take a bit of time to get to a csharp prompt but be patient and you will be greeted with this:
Mono C# Shell, type “help;” for help
Enter statements below.
And now you can freely use the library to interactively control a Phidget from the command line.
csharp> using Phidgets;
csharp> var kit = new InterfaceKit();
Make sure you close any Phidgets you use otherwise you won’t be able to end your shell with `quit;` or `Ctrl+D`. If you tried to quit without closing, you will have to suspend the shell with `Ctrl+Z` and then type `kill %csharp` to kill the shell.
