Introduction to Serverless with .NET + AWS Lambda
summary
A hands-on .NET + AWS Lambda demo shows a .NET MAUI mobile app that POSTs photos to an API Gateway endpoint, a Lambda saves to S3, an S3-triggered Lambda generates a 200×200 thumbnail and returns a pre-signed URL; deployment uses the AWS Toolkit for Visual Studio and one-click publish to Lambda. Cold starts measure about 900ms on .NET 6, with AOT down to ~200–300ms expected; two sample apps cost about $0.14–$0.19/month and the pipeline runs successfully end-to-end.
