I can easily send and receive messages to AWS SQS message queue (standard type) but when I create a FIFO queue and try to send a message I receive an exception which is saying I have to set a non-empty Message group Id.

I found example of this in java at AWS documentation :

**// Send a message

SendMessageRequest sendMessageRequest = new SendMessageRequest(myQueueUrl, "This is my message text.");
*// You must provide a non-empty MessageGroupId when sending messages to a FIFO queue
sendMessageRequest.setMessageGroupId("messageGroup1");*

But when I use the AWS.SQS package in c# I cannot find any properties or method which I can set the Message group Id.

this is the code

SendMessageRequest sendMessageRequest = new SendMessageRequest();
sendMessageRequest.QueueUrl = myQueueUrl; //URL from initial queue creation
sendMessageRequest.MessageBody = "This is my message text.";
sqs.SendMessage(sendMessageRequest);

I had the exact same issue, turned out I needed to install the AWSSDK.Core and AWSSDK.SQS packages and remove the base AWSSDK package I originally had.
