Amazon has released the developer preview of the next major version of AWS SDK for .NET.
Version 2 SDK adds support for Windows Store and Windows Phone apps so you can use the AWS cloud from those platforms. Support has also been added for the .NET task-based asynchronous pattern.
The support for Windows Store and Windows Phone Apps means you can connect your Windows Phone or Windows Store apps to AWS services, and you can build a cross-targeted application that's backed by AWS. Until now AWS mobile support was limited to the big-name duo with SDK for iOS and SDK for Android.
The other big enhancement to the new version is the support for the task-based asynchronous pattern. This pattern uses the async and await keywords and makes it easier to program asynchronous operations against AWS.
The Amazon Web Services Blog gives an example of how you could upload files to S3 asynchronously like this:
async Task UploadFile(string bucketName,
var s3Client = new AmazonS3Client();
var request = new PutObjectRequest()
BucketName = bucketName,
FilePath = filepath
Then this function could be called asynchronously like this:
await UploadFile(bucketName, filepath);
Version 2 of the SDK also includes a version compiled for .NET 3.5 Framework that contains the Begin and End methods for applications that aren't yet ready to move to .NET 4.5.
Another useful change is the ability to set the default region once in the app.config or web.config file, and use that region for all of your SDK calls.
