    MSBuild

    MSBuild

    The Microsoft Build Engine (MSBuild) build platform for .NET and VS

    The Microsoft Build Engine is a platform for building applications. This engine, which is also known as MSBuild, provides an XML schema for a project file that controls how the build platform processes and builds software. Visual Studio uses MSBuild, but MSBuild doesn't depend on Visual Studio. By invoking msbuild.exe on your project or solution file, you can orchestrate and build products in environments where Visual Studio isn't installed. Visual Studio uses MSBuild to load and build managed projects. The project files in Visual Studio (.csproj, .vbproj, .vcxproj, and others) contain MSBuild XML code that executes when you build a project by using the IDE. Visual Studio projects import all the necessary settings and build processes to do typical development work, but you can extend or modify them from within Visual Studio or by using an XML editor. Starting with Visual Studio 2022, when you build in Visual Studio, the 64-bit version of MSBuild is used.

    Windows Presentation Foundation

    Windows Presentation Foundation

    Framework for building Windows desktop applications

    Windows Presentation Foundation (WPF) is a UI framework for building Windows desktop applications. WPF supports a broad set of application development features, including an application model, resources, controls, graphics, layout, data binding and documents. WPF uses the Extensible Application Markup Language (XAML) to provide a declarative model for application programming. WPF applications are based on a vector graphics architecture. This enables applications to look great on high DPI monitors, as they can be infinitely scaled. WPF also includes a flexible hosting model, which makes it straightforward to host a video in a button, for example. The visual designer provided in Visual Studio makes it easy to build WPF application, with drag-in-drop and/or direct editing of XAML markup. WinForms is another UI framework for building Windows desktop applications that is supported on .NET (6.0.x/5.0.x/3.1.x). WPF and WinForms applications only run on Windows.

    XMLUnit provides assertions that help testing code that produces XML.

    XMLUnit 2.x Development Moved to GitHub XMLUnit provides help with testing code that creates or consumes XML. XMLUNit 2.x is available for both Java and .NET with a similar API. Development of this version has moved to a GitHub organization[1] with two git repositories for Java and .NET respectively. All discussion about XMLUnit independent of any version will happen on the XMLUnit general mailing list[2]. XMLUnit for Java 1.x is no longer maintained, please use the legacy artifacts of XMLUnit 2.x if you still need APIs compatible with XMLUnit 1.x. We keep using the Sourceforge infrastructure that has served as well for many years to host forums and mailing lists. XMLUnit for .NET 0.x is not maintained any longer.

    Polly

    Polly

    A .NET resilience and transient-fault-handling library for policies

    Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+. Today's cloud application, mobile, data-streaming, and IoT technologies all depend vitally on reliable connectivity. But underlying systems can fail, and networks are notoriously fickle, outages, latency, transient blips, spikes in load, all challenge 100% reliability. Polly helps you navigate the unreliable network. By providing resilience strategies in fluent-to-express policies such as Retry, WaitAndRetry, and CircuitBreaker, Polly can help you reduce fragility, and keep your systems and customers connected. Example usages are fault-tolerance for any distributed systems and inter-process calls, such as WCF, RESTful calls between microservices, calls to cloud services, Internet of Things connectivity, etc.

    AWS .NET deployment tool

    AWS .NET deployment tool

    The tooling that simplifies deployment of .NET applications

    AWS Deploy Tool is an interactive tooling for the .NET CLI and the AWS Toolkit for Visual Studio that helps deploy .NET applications with minimum AWS knowledge, and with the fewest clicks or commands. It works by analyzing .NET projects and guiding developers to the right AWS service. It then selects the right deployment service, builds and packages your application, and creates the deployment infrastructure. It allows for a quick and easy Proof of concept (POC), smooth graduation to CI/CD, and a gradual ramp-up of AWS knowledge. Get recommendations about the type of computing best suited for your application based on the application type. The tool will generate a Dockerfile if needed, otherwise, an existing Dockerfile will be used. The tool builds the deployment artifacts, generates a deployment CDK project, provisions the infrastructure and deploys your application to the chosen AWS compute.
