Answer 1

You have to specify the "path" to the code you're trying to call. You accomplish this by either

1) Specify the namespace of the second project/class you wish to use, typically at the top of your code file.

using MySecondProject;

var foo = new ClassFromSecondProject();

2) Explicitly specifying the name of the class you wish to use, including its namespace

//do stuff
var foo = new MySecondProject.ClassFromSecondProject();
//do more stuff
