Category: AWS SDK for .NET

In March 2019, AWS announced support for .NET Standard 2.0 in SDK for .NET. They also announced plans to remove the Portable Class Library (PCL) assemblies from NuGet packages in favor of the .NET Standard 2.0 binaries. If you’re starting a new project targeting a platform supported by .NET Standard 2.0, especially recent versions of Unity, Xamarin and […]

We’re pleased to announce the general availability of the ASP.NET Core Identity Provider for Amazon Cognito, which enables ASP.NET Core developers to easily integrate with Amazon Cognito in their web applications. Targeting .NET Standard 2.0, the custom ASP.NET Core Identity Provider for Amazon Cognito extends the ASP.NET Core Identity membership system by providing Amazon Cognito […]

The AWS SDK for .NET is distributed via NuGet packages for each service and a common core NuGet package. Each NuGet package contains different .NET assemblies, depending on your development platform. This includes .NET Framework 4.5, .NET Framework 3.5, the Portable Class Library version for Xamarin, and .NET Standard 1.3. As .NET Core and .NET […]

Yesterday we announced the general availability of the Amazon CognitoAuthentication Extension Library, which enables .NET Core developers to easily integrate with Amazon Cognito in their application. We want to further simplify the integration process into ASP.NET Core, so today we’re releasing the developer preview of the custom ASP.NET Core Identity Provider for Amazon Cognito. Targeting […]

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 […]

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 […]

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 […]

We are releasing support for Amazon S3 Select in the AWS SDK for .NET. This feature enables developers to run simple SQL queries against objects in Amazon S3. Today, if you’re frequently pulling entire objects to use portions of them, this functionality could dramatically improve performance. S3 Select works on objects stored in CSV format or JSON […]
