My Amazon S3 bucket's location is London so when I am trying upload document to this bucket I need to use Amazon.RegionEndpoint.EUWest2 as a region.

```
            Amazon.S3.IAmazonS3 client;
            using (client = Amazon.AWSClientFactory.CreateAmazonS3Client(_awsAccessKey, _awsSecretKey,Amazon.RegionEndpoint.EUWest1))
            {
                var request = new Amazon.S3.Model.PutObjectRequest()
                {

                };

                client.PutObject(request);
            }

```

But somehow I am not able to see any region with name EUWest2 only availble Europe regions are EUWest1 and EUCentral1.
Because of this incorrect regions am getting error as

What can be a reason for it, I am using AWSSDK.dll's 2.3.55.2 version. which I found latest today on Amazon S3 site.
