Additionally, note that AWS Lambda provides the following:

• Amazon.Lambda.Core – This library provides a static Lambda logger, serialization interfaces and a context object. The Context object (AWS Lambda Context Object in C#) provides runtime information about your Lambda function.
• **Amazon.Lambda.Serialization.Json ** – This an implementation of the serialization interface in Amazon.Lambda.Core.
• **Amazon.Lambda.Logging.AspNetCore ** – This provides a library for logging from ASP.NET.
• Event objects (POCOs) for several AWS services, including:
  • **Amazon.Lambda.APIGatewayEvents **
  • **Amazon.Lambda.CognitoEvents **
  • **Amazon.Lambda.ConfigEvents **
  • **Amazon.Lambda.DynamoDBEvents **
  • **Amazon.Lambda.KinesisEvents **
  • **Amazon.Lambda.S3Events **
  • **Amazon.Lambda.SQSEvents **
  • **Amazon.Lambda.SNSEvents **

These packages are available at Nuget Packages.
