The C# SDK is distributed through NuGet.

For Windows, to install, run the following command in a CLI/terminal:

```shell
dotnet add package Optimizely.SDK
```

You may also want to use your IDE's integrated package manager.

The package is on NuGet at [https://www.nuget.org/packages/Optimizely.SDK](https://www.nuget.org/packages/Optimizely.SDK). The full source code is available on [GitHub](https://github.com/optimizely/csharp-sdk).
