The AWS S3 SDK contains functionality that allows creation of a writable stream via the S3FileInfo.OpenWrite method.
http://docs.aws.amazon.com/sdkfornet/v3/apidocs/Index.html
However, support for this method (and the whole Amazon.S3.IO namespace) was dropped in the .Net Core version of the SDK.
Is there an alternative method of generating a writable S3 Stream?
The TransferUtility and PutObject methods can take a readable stream objects as parameters, but neither seems to provide the ability of creating a writable S3 stream.
The following question is similar:
Stream a multi-GB file to AWS S3 from ASP.NET Core Web API
But that use case had a pre-formed file they were looking to upload. My use case involves a stream that will be generated at runtime.
