Noha Basiony: NuGet

NuGet is a Visual Studio extension that makes it easy to install and update open source libraries and tools in Visual Studio that use the .NET Framework.

If you develop a library or tool that you want to share with other developers, you create a NuGet package and store the package in a NuGet repository. If you want to use a library or tool that someone else has developed, you retrieve the package from the repository and install it in your Visual Studio project or solution.

A brief introduction to NuGet.

You can download NuGet

When you install NuGet package, it copies the library files to your solution and automatically updates your project (add references, change config files,… etc.). If you remove a package, NuGet reverses whatever changes it made so that no clutter is left.

Finding and Installing a NuGet Package Using the Package Manager Console:

Install, remove, and update NuGet packages using PowerShell commands.

Using PowerShell commands is required if you want to install a package without having a solution open. It's also required in some cases for packages that create commands that you can access only by using PowerShell.
