What's New?

Change Description
Support for the Asia Pacific (Singapore) Region The AWS SDK for .NET supports infrastructure services in the new Asia Pacific (Singapore) region.

For Amazon S3, you can create a bucket in the new region using the Region enumeration. For example:

PutBucketRequest request = new PutBucketRequest().

For all other services, the region is set using the service URL associated with the client configuration object. For example:

AmazonElasticLoadBalancingConfig config = new AmazonElasticLoadBalancingConfig();
config.ServiceURL = "";
AmazonElasticLoadBalancing elb =
      new AmazonElasticLoadBalancingClient("ACCESS_KEY", "SECRET_KEY", config);

Support for Amazon CloudFront private streaming content The AWS SDK for .NET now supports API version 2010-03-01 of Amazon CloudFront, including support for Private Streaming content, and adds improvements to the output of ListDistributions and ListStreamingDistributions.

Improvements to the Amazon S3 client's support for COPY Object

Users of a CopyObjectRequest can now specify a ContentType for the copied (destination) object. The ContentType is passed on to Amazon S3 only if the metadata directive specified for the request is REPLACE. For example:

CopyObjectRequest request = new CopyObjectRequest();
request.ContentType = "audio/mpeg";
... <provide other request parameters like Source Key, Source Bucket, etc>
CopyObjectResponse response = s3Client.CopyObject(request);

If the REPLACE directive is specified on a request without a ContentType, the SDK makes a best effort to detect the content-type.

Installer changes The AWS SDK for .NET documentation is no longer distributed locally by the installer. Instead, developers can always find the latest documentation online at
Support for Proxy Authentication The SDK now supports making requests through a proxy server. To authenticate requests with the proxy, specify the username and password for an authenticated user using the service's configuration object. For example:

config.ProxyUsername = "User";
config.ProxyPassword = "Password";
AmazonElasticLoadBalancing elb =
     new AmazonElasticLoadBalancingClient("ACCESS_KEY", "SECRET_KEY", config);

Please let us know if there are any additional requirements for making requests through a proxy server on the .NET Development forum.

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:
