    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 (WPF)

    Windows Presentation Foundation (WPF)

    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.

It dramatically expands WinUI into a full UX framework, making WinUI available for all types of Windows apps, from Win32 to UWP, for use as the UI layer. You can build new Windows apps using WinUI 3, which ships as a part of the Windows App SDK. The latest available stable release is the Windows App SDK 0.8 (previously called Project Reunion). With this release, you can ship production Desktop apps to the Microsoft Store.

    SignalR

    SignalR

    Incredibly simple real-time web for .NET

    Today's modern apps are expected to deliver up-to-date information without hitting a refresh button. Add real-time functionality to your dashboards, maps, games and more. What is real-time functionality? It's the ability to have your server-side code push content to connected clients as it happens, in real-time. SignalR hubs can be written in C# code and added to your ASP.NET app, alongside your pages and APIs. The simple programming model integrates seamlessly with other ASP.NET features like dependency injection, authentication, authorization, and scalability. While chat is often used as an example, you can do a whole lot more. Any time a user refreshes a web page to see new data, or the page implements Ajax long polling to retrieve new data, it's candidate for using SignalR. SignalR also enables completely new types of applications that require high-frequency updates from the server, such as real-time gaming.

    XML Unit

    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.
