Building reusable components is one of the basic skills of the computer development world. The reuse of classes that are integrated in a .NET class library has been possible since the beginning of .NET. We are able to compile these classes in a .NET class library project as a DLL (dynamic link library), the implementation of a shared library by Microsoft.
Since the creation of Visual Studio 2010 and ASP.NET MVC's arrival on the scene, the ASP.NET world became more and more open source-friendly, and the necessity to share open source libraries and components became unavoidable.
To share libraries, Microsoft uses NuGet, an open source package manager used to install, uninstall, or update .NET libraries and components on projects through Visual Studio. We can also search for packages from Microsoft or anyone else in the NuGet Online repository, resolve missing packages...
