title: Amazon AWSClientFactory does not exists
body: <p>I created an empty .Net Core application and installed nuget packages for Both Amazon.Core and Amazon.S3. </p>
  
  <p>Then I tried to use S3 to get an object but I'm stuck at the very first moment... Amazon.AWSClientFactory is nowhere to be found inside the assembly. Even with dotPeek I tried to search this factory method but I couldn't find it. Even the sample code from Amazon doesn't work.</p>
  
  <p>Where I supposed to find this class ?</p>
