## Install AWS assemblies with NuGet
<a name="Appendix.DotNETAutoDiscoverySetup.Installing"></a>

NuGet is a package management system for the .NET platform. NuGet is aware of assembly dependencies and installs all required files automatically. NuGet installed assemblies are stored with your solution, rather than in a central location such as `Program Files`, so you can install versions specific to an application without creating compatibility issues.

### Installing NuGet
<a name="Appendix.DotNETAutoDiscoverySetup.Installing.NuGet"></a>

NuGet can be installed from the Installation Gallery on MSDN; see [https://visualstudiogallery.msdn.microsoft.com/27077b70-9dad-4c64-adcf-c7cf6bc9970c](https://visualstudiogallery.msdn.microsoft.com/27077b70-9dad-4c64-adcf-c7cf6bc9970c). If you are using Visual Studio 2010 or later, NuGet is automatically installed.

You can use NuGet from either **Solution Explorer** or **Package Manager Console**.

### Using NuGet from Solution Explorer
<a name="Appendix.DotNETAutoDiscoverySetup.NuGet.SolutionExplorer"></a>

**To use NuGet from Solution Explorer in Visual Studio 2010**

1. From the **Tools** menu, select **Library Package Manager**.

1. Click **Package Manager Console**.

**To use NuGet from Solution Explorer in Visual Studio 2012 or Visual Studio 2013**

1. From the **Tools** menu, select **NuGet Package Manager**.

1. Click **Package Manager Console**.

From the command line, you can install the assemblies using `Install-Package`, as shown following.

```
Install-Package Amazon.ElastiCacheCluster
```

To see a page for every package that is available through NuGet, such as the AWSSDK and AWS.Extensions assemblies, see the NuGet website at [http://www.nuget.org](http://www.nuget.org). The page for each package includes a sample command line for installing the package using the console and a list of the previous versions of the package that are available through NuGet.

For more information on **Package Manager Console** commands, see [http://nuget.codeplex.com/wikipage?title=Package%20Manager%20Console%20Command%20Reference%20%28v1.3%29](http://nuget.codeplex.com/wikipage?title=Package%20Manager%20Console%20Command%20Reference%20%28v1.3%29).
