Applications can be built by using the tools in Visual Studio on Windows, including XAML and C# , and run on iOS, macOS, Android, Windows or in WebAssembly in a web browser.^[5] A plug in for Microsoft Visual Studio is available from Microsoft's Visual Studio Marketplace^[6], VS Code Marketplace ^[7], or JetBrains Rider Marketplace^[8].The community surrounding Uno Platform open source project comes together at its annual conference UnoConf.^[9]
