Learn when to use PutItem vs UpdateItem in DynamoDB from .NET 10. Build a minimal API that upserts inventory, runs partial updates with conditions, and handles errors gracefully-all with AWS Console and Visual Studio 2026.
Secure a Blazor WebAssembly client and a .NET 10 API with Amazon Cognito using the OAuth 2.1 authorization code flow with PKCE and refresh tokens, configured entirely in the AWS console.
Build a simple fan-out pipeline on AWS with SNS and SQS using Terraform and .NET 10 - one orders API publishes events, and two consumers process them independently.
Learn a simple, repeatable way to structure and build Terraform modules on AWS so your .NET services stay consistent, secure, and easy to reuse.
In this hands-on guide, we'll use .NET Aspire 13, DynamoDB Local, and .NET 10 minimal APIs to build a full CRUD Web API against DynamoDB - without ever touching an AWS account. Then we'll see how to flip a small configuration switch to point the same code to real DynamoDB in AWS.
In this hands-on guide, we will use .NET Aspire 13 and the latest .NET 10 SDK to build a cloud-ready notifications system that talks to real AWS services like DynamoDB, SNS, and SQS, while keeping the entire local development experience orchestrated from a single Aspire app host.
Learn how to use ProblemDetails in ASP.NET Core to standardize error responses in your Web APIs. Understand default behavior, customization, exception handling, and best practices for building consistent, developer-friendly APIs.
Learn how to automate the deployment of your .NET applications to AWS App Runner using Terraform. This guide covers infrastructure-as-code setup, CI/CD integration, and practical tips to streamline your cloud deployments.
Learn how to extract text from PDF documents using AWS Textract and .NET-based AWS Lambda functions. This guide walks .NET developers through building a serverless OCR pipeline using S3 triggers, Textract integration, and real-world implementation tips for handling document processing in the cloud.
Learn how to efficiently upload large files in ASP.NET Core using Amazon S3's multipart upload feature and pre-signed URLs. This hands-on guide walks you through building a scalable, client-driven upload workflow using a .NET 9 Web API and a Blazor WebAssembly frontend. You'll learn how to generate pre-signed URLs, handle file chunking, perform parallel uploads, and finalize the upload with minimal server load. Ideal for developers looking to offload file handling to S3 while maintaining full control from a .NET-based stack.
Learn how to build scalable, fault-tolerant serverless workflows using AWS Step Functions and .NET Lambda functions. This guide is tailored for .NET developers who want to move beyond simple Lambda functions and orchestrate complex workflows with retries, parallel executions, and state management. We’ll cover the basics of Step Functions, how they integrate with .NET Lambda projects, real-world architecture examples, setup instructions, error handling, and when to avoid using them.
Learn how to build a fully serverless, production-ready image processing pipeline on AWS using .NET. This guide walks through uploading images via a minimal .NET 9 Web API, triggering S3 event notifications to an SQS queue, and processing those events in a Lambda function using ImageSharp. You'll learn how to resize images into optimized thumbnails, upload them to an output S3 bucket, and monitor the workflow using CloudWatch. The architecture is event-driven, scalable, and cost-efficient - ideal for modern applications handling user-generated content.
