How to use DigitalOcean Spaces with the AWS S3 SDKs?

Working C# example using Amazon AWSSDK (V2.x).

IAmazonS3 amazonS3Client = 
	AWSClientFactory.CreateAmazonS3Client("your-spaces-key", "your-spaces-key-secrete",
	new AmazonS3Config
	{
	   ServiceURL = "https://nyc3.digitaloceanspaces.com"
	}
);
var myBuckets = amazonS3Client.ListBuckets();

Go - (AWS Docs)

package main

import (
    "fmt"

func main() {
    // Initialize a client using Spaces
    s3Config := &aws.Config{
        Credentials: credentials.NewStaticCredentials("ACCESS_KEY", "SECRET_KEY", ""),
        Endpoint:    aws.String("https://nyc3.digitaloceanspaces.com"),
        Region:      aws.String("us-east-1"), // This is counter intuitive, but it will fail with a non-AWS region name.
    }

    newSession := session.New(s3Config)
    s3Client := s3.New(newSession)

    // Create a new Space
    params := &s3.CreateBucketInput{
        Bucket: aws.String("my-new-space-with-a-unique-name"),
    }

    _, err := s3Client.CreateBucket(params)
    if err != nil {
        fmt.Println(err.Error())
        return
    }

    // List all Spaces in the region
    spaces, err := s3Client.ListBuckets(nil)
    if err != nil {
        fmt.Println(err.Error())
        return
    }

    for _, b := range spaces.Buckets {
        fmt.Printf("%s\n", aws.StringValue(b.Name))
    }

    // Upload a file to the Space
    object := s3.PutObjectInput{
        Body:   strings.NewReader("The contents of the file"),
        Bucket: aws.String("my-new-space-with-a-unique-name"),
        Key:    aws.String("file.ext"),
    }
    _, err = s3Client.PutObject(&object)
    if err != nil {
        fmt.Println(err.Error())
        return
    }
