New Features

Change Description
Amazon Simple Workflow

The AWS SDK for .NET now supports Amazon Simple Workflow (Amazon SWF). Amazon SWF is an orchestration service for building scalable, resilient applications. Using Amazon SWF, developers can structure the various processing steps in an application as tasks that drive independent, distributed components and orchestrate these tasks in a reliable and scalable manner.

Here is a sample of what an application might look like to poll bugs coming in through a work flow and have them be triaged.
PollForDecisionTaskRequest pollDeciderRequest = new PollForDecisionTaskRequest()
    Domain = "bug-queue",
    Identity = "triage"

while (true)
    PollForDecisionTaskResponse pollDeciderResponse = swfClient.SimpleWorkflowClient.PollForDecisionTask(pollDeciderRequest);
    DecisionTask task = pollDeciderResponse.PollForDecisionTaskResult.DecisionTask;

    // If there are no events then there was no bug to triage currently so go back and poll.
    if (task.Events != null)
Amazon RDS support for VPC This release introduces support for running your DB Instances in an Amazon Virtual Private Cloud (VPC).

Resolved Issues

Issue Description
AmazonRoute53Client Fixed an issue with AmazonRoute53Client where parameters were not being correctly passed to the service.
AmazonS3Client Keep Alive AmazonS3Client was modified to enable HTTP keep alive for better performance.
System.Web Dependency The dependency on System.Web was removed so that the SDK can work in the .NET client profile.
AmazonEC2Client Exception Handling Updated AmazonEC2Client to throw the original exception when all retry attempts have been exhausted.

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:
