Get started with Windows: Selecting a development technology

This article contains the information you need to get started building apps for the Windows desktop environment.

Developer at desk

Windows gives you huge flexibility when it comes to building apps. From C++ and .NET to more up-and-coming tools such as open source tools on WSL and Rust, there are many different languages and platforms to choose from. It can be quite overwhelming to know where to start.

Visual Studio is the development environment used by most Windows developers and it provides many types of app starting points, each with their own project types and different strengths. Each app type includes an app model that defines the lifecycle of the app, a default UI framework, and access to a comprehensive set of APIs for using Windows features.

If your new app is going to run only on Windows, we recommend using the Windows App SDK and WinUI 3. If you need your app to run on multiple platforms, we recommend looking at .NET MAUI or React Native for Windows. There are plenty of other options too (if you love tools like Python, here's a list) but here are some recommendations to get started.

Create a WinUI 3 app

The Windows UI Library (WinUI) 3 is the latest and recommended user interface (UI) framework for Windows desktop apps, including managed apps that use C# and .NET and native apps that use C++ with the Win32 API. By incorporating the Fluent Design System into all experiences, controls, and styles, WinUI provides consistent, intuitive, and accessible experiences using the latest UI patterns.

WinUI 3 is available as part of the Windows App SDK. The Windows App SDK provides a unified set of APIs and tools that can be used in a consistent way by any C++ Win32 or C# .NET app on a broad set of target Windows OS versions.

If you have already installed the required developer tools, you are ready to Create your first WinUI 3 project.

Cross-platform options

WinUI also serves as the basis for cross-platform technologies that provide great native Windows experiences using a variety of coding languages. These frameworks harness the power of WinUI on Windows, while also enabling execution on other operating systems.

.NET Multi-platform App UI (MAUI) is an open-source, cross-platform framework for building Android, iOS, macOS, and Windows applications that leverage the native UI and services of each platform from a single .NET code base. Because .NET MAUI favors platform native experiences, it uses WinUI 3 and the Windows App SDK so apps get the latest user experience on Windows. This gives your apps access to everything you get with WinUI 3 plus the ability to reach to other platforms.

.NET MAUI for Windows is a great choice if:

  • You want to share as much .NET code as possible across mobile and desktop applications.
  • You want to ship your application beyond Windows to other desktop and mobile targets with native platform experiences.
  • You want to use C# and/or XAML for building cross-platform apps.
  • You're using Blazor for web development and wish to include all or part of that in a mobile or desktop application.

Other app types

For more information about the app types you can choose from, see the following tabs.

Win32 desktop apps (also sometimes called classic desktop apps) are the original app type for native Windows applications that require direct access to Windows and hardware. This makes this the app type of choice for applications that need the highest level of performance and direct access to system hardware.

Using the Win32 API with C++ makes it possible to achieve the highest levels of performance and efficiency by taking more control of the target platform with unmanaged code than is possible on a managed runtime environment like WinRT and .NET. However, exercising such a level of control over your application's execution requires greater care and attention to get right, and trades development productivity for runtime performance.

Here are a few highlights of what the Win32 API and C++ offers to enable you to build high-performance applications.

  • Hardware-level optimizations, including tight control over resource allocation, object lifetimes, data layout, alignment, byte packing, and more.
  • Access to performance-oriented instruction sets like SSE and AVX through intrinsic functions.
  • Efficient, type-safe generic programming by using templates.
  • Efficient and safe containers and algorithms.
  • DirectX, in particular Direct3D and DirectCompute (note that UWP also offers DirectX interop).
  • Use C++/WinRT to create modern desktop Win32 apps with first-class access to Windows Runtime (WinRT) APIs.

You also have access to modern Windows platform features and APIs provided by the Windows App SDK. For more information, see Modernize your desktop apps.
