AWS Lambda: how to add S3Event trigger?

I have a AWS Lambda NET 6 function. It was created in VS2022 with template using 2 entry points

LambdaEntryPoint LocalEntryPoint to run in AWS or in a local environment.

How can I add S3 Event trigger to the lambda?

Hello Oleg. Are you using CDK or CloudFormation to create your S3 bucket? Or is it an existing one that you only want to add an event to trigger the Lambda function?

Our legacy app stores files on local/network disk. By design my Lambda should create buckets with files. It is something like user deal1\file101 user deal1\file102, user deal2\file201 etc. I.e. user uploads files and in that moment the lambda should create buckets &|| file.

Ok, thank you. But what changes should I do in the LambdaEntryPoint ?

The only change is handling the event information (JSON document) that is passed to the Lambda function so it knows what event is about, and the object details. The event information is typically the first parameter in the function's entry point.
