How-To: Creating an application with Uno.Extensions

This tutorial will walk you through how to create an Uno application with Uno.Extensions using the Wizard and CLI.


Make sure to setup your environment first by following our instructions.


1. Creating the app

Create an Uno Platform app with Wizard

  • Create a new C# solution using the Uno Platform App template, from Visual Studio's Start Page, then click the Next button

    Visual Studio - Get started - Selecting create a new project option Visual Studio - Create a new project - Selecting Uno Platform App option

  • Configure your new project by providing a project name and a location, check the "Place solution and project in the same directory" option, then click the Create button

    Visual Studio - Configure project name and location

  • Choose a template preset to build your application

    Visual Studio - Configure your new project


    For a detailed overview of the Uno Platform project template wizard and all its options, see this.

  • Click the create button

  • Wait for the projects to be created, and their dependencies to be restored

Create an Uno Platform app with the CLI

The dotnet templates included in the Uno.Templates package are used to easily create new projects that already reference the Uno.Extensions.

  • Open a command prompt and run the following:

    dotnet new install Uno.Templates
  • Navigate to the desired projects directory, and use the unoapp template to generate the starter solution discussed above

    dotnet new unoapp -o MyProject -preset recommended

    The argument specified after the -o flag (i.e. MyProjectName) will act as the name for both a containing directory and the generated solution.

  • Open the solution in Visual Studio


2. Exploring the Solution

The generated solution will contain MyProjectName for application logic, including constructs like ViewModels and services, along with the pages, controls, and other views constituting the UI of the application.
