Process of Installing the Nuget Package Manager in ASP.NET Web API

Introduction

In this article we will define what the NuGet Package Manager is and how to installed it in the ASP.NET Web API.

What the NuGet Package Manager Is

The NuGet Package Manager is a Visual Studio extension that helps add, remove and update the libraries of ASP.NET projects. The NuGet Package Manager is for the Microsoft Visual Studio development platform that includes the  .Net framework. When we install the NuGet package manager it can copy the files and perform the changes that are required.

These changes are automatically performed by the NuGet package manager at the time of installation. The changes performed include addition of references and modifying the web.config and app.config.

How the NuGet Package Manager Works

The NuGet Package Manager includes the files of a project to copy and creates a manifest file that describes the contents of the package. And determines what  libraries needs to be added and removed. Packages are bundled into feeds that are accessed by Visual Studio for the presentation of a list of available packages.

The NuGet Package Manager dialog box loooks like:
