New Features

Change Description
MFA-protected access through AWS Identity and Access Management

You can now enforce MFA authentication for AWS service APIs via AWS Identity and Access Management (IAM) policies. This provides an extra layer of security over powerful operations that you designate, such as terminating Amazon EC2 instances or reading sensitive data stored in Amazon S3.

To use MFA-protected access, request a session token using an AmazonSecurityTokenServiceClient instance, providing details of the MFA device:

//using Amazon.SecurityToken;
//using Amazon.SecurityToken.Model;
//using Amazon.Runtime;
//using Amazon.EC2;

AmazonSecurityTokenServiceClient stsClient = new AmazonSecurityTokenServiceClient(/* usual AWS credential options here */);

GetSessionTokenRequest sessionTokenRequest = new GetSessionTokenRequest();
sessionTokenRequest.SerialNumber = "MFA device serial number";
sessionTokenRequest.TokenCode = "MFA generated token code";
GetSessionTokenResponse sessionTokenResponse = stsClient.GetSessionToken(sessionTokenRequest);

// sessionTokenResponse.GetSessionTokenResult.Credentials contains session credentials for further 
// AWS client instantiation, for example:

Credentials stsCredentials = sessionTokenResponse.GetSessionTokenResult.Credentials;
SessionAWSCredentials sessionCredentials = new SessionAWSCredentials(stsCredentials.AccessKeyId, 
AmazonEC2Client ec2Client = new AmazonEC2Client(sessionCredentials);

For more information see the Configuring MFA-Protected API Access documentation.

Amazon DynamoDB

Signature Version 4 has been enabled for Amazon DynamoDB.

Amazon EC2 Multiple IP Addresses

Instances in a VPC can be assigned one or more private IP addresses, each of which can be associated with its own Elastic IP address. With this feature you can host multiple websites, including SSL websites and certificates, on a single instance where each site has its own IP address. Private IP addresses and their associated Elastic IP addresses can be moved to other network interfaces or instances, assisting with application portability across instances.

For more information about using multiple IP addresses with EC2 instances, see Using Multiple IPs with Your VPC.

Known Issues

Issue Description
Installation Requires Administrator Privileges The default install location is %PROGRAMFILES%, which on most computers is "c:\program files". In order to install files to the default location, the MSI must be run by an Administrator. If you don't have Administrator privileges on the machine, please change the install location to something like "c:\Documents and Settings\\AWS SDK for .NET", and the install will complete successfully. If you are running on Vista, your personal folder is similar to "c:\users\\".
Uninstalling the SDK Produces "Unknown Publisher" Message On Windows Vista, uninstalling the MSI results in an "Unknown Publisher" dialog even though the installer is signed by Amazon Web Services. This is a known Windows Installer bug on Windows Vista, and is documented here:
