Answer 1

Your aws credential file is stored in ~/.aws/credentials (on Linux) or "%UserProfile%\\.aws\\credentials" on Windows. By default the .NET SDK will retrieve your credentials from this file default profile.

To set up a default profile, you have to write your access key and secret acces keys in this file as follows:

[default]
aws_access_key_id=YOUR_ACCESS_KEY
aws_secret_access_key=YOUR_SECRET_ACCESS_KEY

See Configuration and Credential File Settings for more details

If you don't have those credentials, you can go to your IAM user in the AWS console and download them as a .csv for example
