New Features

Amazon DynamoDB Checksumming

Amazon DynamoDB calculates a CRC32 checksum of the HTTP payload and returns this checksum in a new header. The SDK will compute the checksum from the payload it receives and retry the request in case of data corruption in transit indicated by different checksums.

Amazon DynamoDB Consistent Batch Gets

By default, read operations performed by the BatchGetItem API are eventually consistent. A new ConsistentRead parameter in BatchGetItem lets customers choose read consistency instead, for any table(s) in the request.

Amazon RDS Read Replica Promotion This release adds support for promoting an Amazon RDS Read Replica to a standard DB Instance. For more information, see the Working with Read Replicas section in the Amazon Relational Database User Guide.

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\<you>\AWS SDK for .NET", and the install will complete successfully. If you are running on Vista, your personal folder is similar to "c:\users\<you>\".
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:
