# AWS SDK for C# With Wasabi

[AWS SDK for .NET](https://aws.amazon.com/sdk-for-net/) is a framework used for C# coding and is validated for use with Wasabi. This framework can be used with Wasabi by simply pointing the endpoint to a service URL that corresponds to a Wasabi region. To use the C#/.NET SDK with Wasabi, proceed with the following steps.

*This was tested with AWS SDK version 4.*

1. Download [JetBrains Rider](https://www.jetbrains.com/rider/)****IDE (you may use any IDE as per your requirements). In this example, we will be using NuGet packages.
2. Create a **project** in JetBrains. Navigate to **NuGet** to download and install the required AWS SDK packages.

3. Type “AWS” in the search bar to see a list of all AWS SDKs. For our use case with Wasabi S3, install the following packages:

  - AWSSDK.Core
  - AWSSDK.S3
4. Configure an additional [AWS CLI profile for Wasabi](https://docs.wasabi.com/docs/how-do-i-use-aws-cli-with-wasabi) account using the Wasabi keys.

**

It is optional for you to use credential files to run your code; however it is always a best practice to use such an implementation wherein your credential keys are in a file stored on your local machine rather than part of your actual code.

In this example, we set the profile name as "*wasabi*" in the "~/.aws/credentials" file.
5. Below is sample code to upload objects to Wasabi.

> [!NOTE]
> This example discusses the use of Wasabi's us-east-1 storage region. To use other Wasabi storage regions, use the appropriate Wasabi service URL as described in [Service URLs for Wasabi's Storage Regions](https://docs.wasabi.com/docs/what-are-the-service-urls-for-wasabi-s-different-storage-regions).

> [!NOTE]
> Wasabi currently does not support the value STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER for the X-Amz-Content-Sha256 header. As a result, we recommend disabling chunked transfer encoding in applications while uploading the object using the .NET SDK by setting UseChunkEncoding = false until support is available.

> [!NOTE]
> Be sure to use your own BucketName, Profile Name, and Client info/version (replace YourClientInfo/v1.2.3).

```csharp
using Amazon.Runtime;
using Amazon.Runtime.CredentialManagement;
using Amazon.S3;
using Amazon.S3.Model;

namespace AWSWasabi
{
    public static class UploadWasabiObject
    {
        private static IAmazonS3 _s3Client = null!;

        private const string BucketName = "mt-aws-sdk-test";
        private const string ObjectName1 = "test.txt";

        // Updated to take any object from the desktop, just adjust the file name above
        private static readonly string PathToDesktop =
            Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

        private static async Task Main()
        {
            // 1. Configure the S3-compatible endpoint (Wasabi) using the correct URL for your
            // bucket's region and your client's info and version number
            var config = new AmazonS3Config
            {
                ServiceURL = "https://s3.us-east-1.wasabisys.com",
                ClientAppId = "YourClientInfo/v1.2.3"   // adds: app/YourClientInfo/v1.2.3 to
                                                        // the User-Agent header
            };

            // 2. Load credentials from a named profile (replaces StoredProfileAWSCredentials)
            var chain = new CredentialProfileStoreChain();
            if (!chain.TryGetAWSCredentials("wasabi", out AWSCredentials awsCredentials))
            {
                Console.WriteLine("Could not find AWS profile 'wasabi'");
                return;
            }

            // 3. Create S3 client with credentials and config
            _s3Client = new AmazonS3Client(awsCredentials, config);

            // The method expects the full path, including the file name.
            var path = Path.Combine(PathToDesktop, ObjectName1);

            await UploadObjectFromFileAsync(_s3Client, BucketName, ObjectName1, path);
        }

        private static async Task UploadObjectFromFileAsync(
            IAmazonS3 client,
            string bucketName,
            string objectName,
            string filePath)
        {
            try
            {
                var putRequest = new PutObjectRequest
                {
                    BucketName = bucketName,
                    Key = objectName,
                    FilePath = filePath,
                    UseChunkEncoding = false
                };

                putRequest.Metadata.Add("x-amz-meta-title", "someTitle");

                await client.PutObjectAsync(putRequest);
                Console.WriteLine("Upload completed.");
            }
            catch (AmazonS3Exception e)
            {
                Console.WriteLine($"Error: {e.Message}");
            }
        }
    }
}
```
6. Build and run your code in JetBrains. The exit code 0 indicates that everything ran successfully.

7. You can now see the object in your bucket by logging into the [Wasabi Console](https://console.wasabisys.com).
