<a name="configuring-the-sdk"></a>

To use the AWS SDK for .NET, you need to [set up your environment](net-dg-config.md) and also configure a number of essential things that your application needs to access AWS services. These include:
+ Specification of the AWS Region
+ AWSSDK packages or assemblies

Some of the topics in this section provide information about how to configure these essential things.

Other topics in this section and other sections provide information about more advanced ways that you can configure your project.
