    Has anyone used DI for aws lambda functions? I was wondering if there was a recommended way. currently i am just using the built in dotnetcore DI
    public async Task<string> FunctionHandler(S3Event evnt, ILambdaContext context)
                var serviceCollection = new ServiceCollection();
                // service provider 
                var serviceProvider = serviceCollection.BuildServiceProvider();
                // entry to run app 
                var service = serviceProvider.GetService<ApplicationService>();
                return await service.LocalFunctionHandler(evnt, context);
            public void ConfigureServices(IServiceCollection services)
                services.AddSingleton<IAmazonS3>(s3 => new AmazonS3Client(Amazon.RegionEndpoint.USEast1));
                services.AddSingleton<IAmazonBatch>(batch => new AmazonBatchClient(Amazon.RegionEndpoint.USEast1));
    Hi there, I just post on Github regarding Unity support. With Unity supporting a newer version of Mono (finally), I was wondering if it would be possible/easy to get the aws-sdk-net running in Unity. I had a look, and it looks like the biggest blocker is the use of System.Configuration which is not supported, but should otherwise be fine, right? :)
    Anyway, I am trying to decide a backend, and I love AWS's offerings but the Unity SDK being so outdated is a real bummer. Google/Google Cloud has recently partnered with Unity to provide a complete multiplayer solution for unity. I think AWS can easily rival them.
    Hi, is it possible to build an app to manage s3 for uploading file using username and password instead of access id and key?
    @Gkanda80 not sure you can do it using IAM accounts. What are you trying to do? Perhaps you can tie usernames and passwords to keys within your app?
    Is anyone else having problems uploading pdf docs to s3? It seems that when the key ends with .pdf PutObject doesn’t return ie it hangs. If I change the extension to .txt or -pdf it works perfectly. I’m guessing the api is doing something extra when it detects the application/pdf ContentType.
    Hey, I have created a user pool on Cognito and am able to authenticate the user using the _signInManager.PasswordSignInAsync() in a .netcore app that has both razor pages and API. Now i want to access the ID token so that i can pass it for any subsequent calls to the API from the client. once i have signed in how to i access the ID token?

    @gopinathrimc I am trying the same thing
    var token = await HttpContext.GetTokenAsync("access_token").ConfigureAwait(false);
    var token1 = await HttpContext.GetTokenAsync("id_token").ConfigureAwait(false);
    var accesToken = Request.Headers["Authorization"];
    var refreshToken = await HttpContext.GetTokenAsync("refresh_token").ConfigureAwait(false);
    return null
    @jobairkhan dont know if the approach am taking is correct, but what i ended up doing is after _signInManager.PasswordSignInAsync() , i made a separate call using SrpAuth to get to the token.
            AuthFlowResponse authResponse = await user.StartWithSrpAuthAsync(new InitiateSrpAuthRequest { Password = inPassword });
            string idToken = authResponse.AuthenticationResult.IdToken;

    @sstevenkang What is the process for approving pull requests?

    Hi. I'm currently sending a message to an SQS queue with success.
    However I've noticed that when I GET/read a message , it says "List of messages" ?
    In other words , how come I send a single message but it shows me a List of messages when I want to get a message .....?

    anyone have an example of using AWSSDK.AWSHealth in c#?

    Hi, is any maintainers here? Issue #1196 was closed, but the problem still exists.
    We reword it to match root case better but have no response from @klaytaybai =(
    Can someone reopen it?
    There is not possible to make PutObjectRequest with key ending with whitespaces.
    Hi @aotd1, both PutObject and GetObject allow keys with whitespaces--as they should. Using a VersionId with whitespace at the end is not supported by the SDK because it is not supported by the S3 service. If we were to reopen this, it would probably be very low priority for some time unless the service started supporting VersionIds with whitespace at the end.
    Alexey Ashurok

    @klaytaybai VersionId with whitespace is only our problem, I understand it.
    The common problem is that this code crashes too:

    var client = new AmazonS3Client(bucketRegion);
    var request = new PutObjectRequest
                        Key = "test ",
                        BucketName = "bucket",
                        ContentBody = "test"
    using (var response = await client.PutObjectAsync(request))

    with SignatureDoesNotMatch.

    It's because signing request don't use TrimEnd(), but CanonicalizedResource use.
    So we send http://blablabla/?key=test, but sign
    @aotd1, let's move this conversation back to the issue. Could you please provide a link to a repro solution so I can see if there are other configurations that may be involved? I have been able to get this request to work consistently using the same style of parameters (i.e. space at end of key).
    is there any sample out there for sharing DB Connection between lambda execution?

    I'm receiving S3 errors when running a project in Visual Studio 2019, but which works just fine in VS 2017. The error happens when instantiating an AmazonS3Client :

    AmazonS3Client s3Client = new AmazonS3Client(RegionEndpoint.USEast1);

    and getting the error:
    System.ArgumentException HResult=0x80070057 Message=An item with the same key has already been added. Key: System.Collections.Generic.Dictionary2[System.String,System.Collections.Generic.Dictionary2[System.String,System.Object]] Source=System.Private.CoreLib StackTrace: at System.ThrowHelper.ThrowAddingDuplicateWithKeyArgumentException[T](T key)

    Anyone know where there are any samples for .net core to pretty much any of the services? Struggling to find examples, especially to Amazon Connect.
    Michael Jan
    @dillorscroft same here, I tried looking for examples for .net core and pretty much gave up, the support is very poor for .net core in regards to aws. I ended up using Xamarin with Azure instead.
    @dillorscroft, what are you hoping to do with Amazon Connect? If we can get more customer feedback about which services and features need more documentation and samples, we can try to make those a higher priority.
    Does anybody know how to solve uploading files with Chinese characters name?When I upload them ,I will get a exception SignatureDoesNotMatch.

    Is there active development for the .Net SDK? Some reported issues on the GitHub repository are so old and with little response. That is concerning.
    Does anyone have any working sample for the KMS (Kafka) configuration using the .Net SDK?

    anyone know what the difference between AWSSDK.CloudSearch and AWSSDK.CloudSearchDomain is?
    @phillip-haydon thanks for the feedback on this. We'll get it updated. AWSSDK.CloudSearch is the configuration API for setting up CloudSearch domains. AWSSDK.CloudSearchDomain is the API for both document management (adding, deleting, replacing) within your domain and searching your domain. You can see more details by looking at the code or referencing the service's documentation here: https://docs.aws.amazon.com/cloudsearch/latest/developerguide/api-ref.html. I updated your GitHub issue too.

    May I know the average response time of AWS SDK API for .Net?
    How good is your network connection?
    There's very little actual overhead in the SDK. It's mostly just wrapping REST API calls.

    Quick question: do the maintainers of the AWS-NET-SDK accept pull requests? There is no CONTRIBUTING.MD or guidelines for contributing like other AWS repos...
    maybe someone from AWS can respond? @fulghum ?
