I have been trying to diagnose some annoying intermittent errors I see thrown by AWSSDK, which include it trying to locate my AWSSDK profile/credentials files.
I used this guide to create them: https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/net-dg-config-creds.html

To fix this, I created the profiles and credentials in a flat file and put references to them in <appSettings>:
<add key="AWSProfilesLocation" value="C:\Users\Administrator\.aws\credentials" />
<add key="AWSProfileName" value="default" />
<add key="AWSAccessKey" value="ABC123" />
<add key="AWSSecretKey" value="DEFG6789" />
<add key="AWSBucketName" value="media.mysite.com" />

This addition works well in projects I use that do not have CloudUploaders, such as WebAPIs and services. Unfortunately, if I add these lines to a project with CloudUploader, it makes it so the uploader barks on every single upload, as if all files are invalidated or errored when attempting to select one. The project doesn't spit out a useful error so I'm not 100% sure whats happening.

For reference the error(s) I was getting that caused me to dive down this rabbit hole were:

System.IO.__Error.WinIOError

Hello Alex,

The first thing that I can see is that you set C:\users\administrator while the error is trying to read C:\Windows\system32\config\systemprofile\ folder for the credentials.

You can see that there is an open issue for the AWS SDK in github with the same error:

There are some other links addressing similar issue that might be fixed with a later version of the SDK:

Please check how an upgrade of the Amazon SDK would affect the scenario.
