How to Install a C# Class Library in Visual Studio?

A C# library project is a separate project used to hold utility classes. So this might be the class that handles our database or might handle some communications with the network. In our case, we are going to create a math library that is a stand-in for some of those other cases. It is a single source of code if we have a shared library among several projects. It is also a separation of concerns so that we do not have all our code in one class in our project. We separate it according to the layers in our project so that it could separate according to the user interface layer, business logic, or maybe data repository.
