We’re excited to announce the general availability of the Amazon CognitoAuthentication Extension Library! The general availability release adds security, improves performance, and fixes bugs to the previously available developer preview. This library simplifies the authentication process of Amazon Cognito user pools for .NET Core and Xamarin applications, and targets .NET Standard 2.0. Amazon Cognito user […]

Today, we released a new NuGet package, Amazon.Extensions.Configuration.SystemsManager. This NuGet package simplifies how your application loads the application configuration settings in the AWS Systems Manager Parameter Store into the .NET Core configuration system. Configuration in .NET Core is quite different from what we’re used to in the .NET Framework. With the .NET Framework, we had […]

The antiforgery framework is a critical part of ASP.NET Core. It ensures web forms and login pages haven’t been tampered with by storing crypto data with the form and then validating the form with a key created by the Data Protection framework. An ASP.NET Core Data Protection Provider is the building block that provides encryption […]

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 […]
