Another way to configure an application is to edit the appSettings element in the project's App.config

or Web.config file.The following example specifies the AWSRegion (p. 16) and AWSLogging (p. 15)

parameters.

</appSettings>

</configuration>

These settings take affect only after the application has been rebuilt.

Although you can configure an SDK for .NET application programmatically by setting property values in

the AWSConfigs class, we recommend that you use the aws element instead.The following example

specifies the AWSRegion (p. 16) and AWSLogging (p. 15) parameters:

AWSConfigs.AWSRegion = "us-west-2";

AWSConfigs.Logging = LoggingOptions.Log4Net;

Programmatically defined parameters override any values that were specified in an App.config or

Web.config file. Some programmatically defined parameter values take effect immediately; others take

effect only after you create a new client object. For more information, see Configuring AWS

Credentials (p. 9).

Configuring AWS Credentials

This topic describes how to configure your application's AWS credentials. It assumes that you have

created an AWS account and that you have access to your credentials, as described in Create an AWS

Account and Credentials (p. 3). It is important to manage your credentials securely and avoid practices

that could unintentionally expose your credentials publicly. In particular:

• Don't use your account's root credentials to access your AWS resources.

These credentials provide unrestricted account access, and are difficult to revoke.

• Don't put literal access keys in your application, including the project's App.config or Web.config

file.

Doing so creates a risk of accidentally exposing your credentials if, for example, you upload the project

to a public repository.

Some general guidelines for securely managing credentials include:

• Create IAM users and use those credentials to provide account access instead of your account's root

credentials.
