AWS Developer Tools Blog

When building a serverless application on AWS, AWS CloudFormation is incredibly important for deploying your AWS Lambda functions and the AWS resources that your application will interact with. With our AWS .NET Core Lambda tooling, when you create a serverless application an AWS CloudFormation template is added to your project. The template enables you to […]

How to debug AWS Lambda functions is one of the most common questions we get from developers creating Lambda functions for .NET Core. The best practice is to write repeatable and automated tests to ensure that your functions stay correct as you make changes to them using frameworks like xUnit.net. The programming model for Lambda […]

We’re pleased to announce that the AWS SDK for Java 2.x is now generally available and supported for production use. Version 2.x is a major rewrite of the 1.11.x code base. Built with support for Java 8+, 2.x adds several frequently requested features, like nonblocking I/O, improved start-up performance and automatic iteration over paginated responses. […]

We’re happy to announce the developer preview of the AWS SDK for JavaScript, version 3. This version of the SDK is a major rewrite of the 2.x code base. It’s written in TypeScript and adds frequently requested features, like modularized packages. Many aspects of the SDK have been refactored and cleaned up in addition to […]

This blog was authored by Mike Cowgill, Principal Engineer at Intuit (maker of TurboTax and QuickBooks) and active collaborator in the AWS Cloud Development Kit open source community. What is exciting about the AWS CDK? First, if you don’t know what the AWS Cloud Development Kit (CDK) is, check out the GitHub project or CDK’s […]

In part 1 of this blog post, we explored using the lightweight dependency injection (DI) provided by Microsoft.Extensions.DependencyInjection. By itself, this is great for libraries and small programs, but if you’re building a nontrivial application, you have other problems to contend with: You might have complex configuration needs (development versus production, multiple sources, etc.) How […]

Dependency injection (DI) is a central part of any nontrivial application today. .NET has libraries like Ninject for implementing inversion of control (IOC) in their development and, as of .NET Core 1.0 (specifically, .NET Standard 1.1), lightweight DI can be provided by Microsoft.Extensions.DependencyInjection. This was used primarily in the context of developing .NET Core web applications, but it can be […]

Summary: This blog post describes best practices for using DateTime values in distributed .NET programming. It also highlights some of the recent, related changes in the AWS SDK for .NET and the AWSPowerShell modules. Today, it’s increasingly common to write code that interacts with external systems, and it’s very likely that these systems won’t share the […]

With the recent AWS Lambda support for PowerShell, it’s now easy to make web APIs with Amazon API Gateway that execute your PowerShell scripts. In the previous blog post, we showed how to deploy PowerShell-based Lambda functions with AWS CloudFormation. We are going to reuse that technique in this post because using AWS CloudFormation is […]

If your application is using .NET Framework 3.5 or 4.5 you should update to version 3.3.22.0 or later of AWSSDK.Core. This ensures you are using the latest HTTPS protocols and can communicate with newer AWS services. Background A growing trend across the internet is for HTTPS services to only accept connections using newer encryption protocols […]
