Getting Started with NuGet Packages step by step overview.

We can all see lots of buzz about NuGet in asp.net world. So I decided to explore it. let’s explore it in some details. Following is a explanation of NuGet Extension on the code plex here.

"NuGet is a Visual Studio extension that makes it easy to add, remove, and update libraries and tools in Visual Studio projects that use the .NET Framework. When you add a library or tool, NuGet copies files to your solution and automatically makes whatever changes are needed in your project, such as adding references and changing your app.config or web.config file. When you remove a library, NuGet removes files and reverses whatever changes it made in your project so that no clutter is left."

So in simple words is a Visual Studio Extension which will help you the add,remove and update libraries in your visual studio project.

Installing NuGet

Let’s see how we can install it. For that first you have to go thorough the Tools->Extension Manager and then search for nuget and it will appear in the list like below.

After that click on download and it will download and install it from the web. Make sure your computer has access to internet. Once you download your nugest extension it will ask you to restart visual studio. So once your are restarted you are ready with nuget packages.
