Using Codespaces

Developing an Uno App using Codespaces

The easiest way to get started is to visit the Uno.QuickStart repository. It allows you to get started with minimal configuration or project creation steps.

To create a new Codespace, visit GitHub Codespaces.

Developing for WebAssembly

  1. Install the suggested Uno Platform extension
  2. Open the command palette (Ctrl+Shift+P) and execute the Run uno-check command to install the appropriate .NET SDK
  3. Open the command palette (Ctrl+Shift+P) and run the Install the dotnet new templates command to install the dotnet new templates
  4. Once the C# environment is setup, with the command palette use the command "Omnisharp: Select project" (or click on the project name in the status bar)
  5. Select the MyApp project
  6. Using a terminal, navigate to the MyApp folder
  7. Type dotnet run -f net10.0-browserwasm
  8. Once the compilation is done, a server will open on port 5000
  9. In the Ports tab (next to the Terminal tab), right click to make both the port 5000 and the other dotnet opened port (with uno.winui.devserver or uno.ui.remotecontrol in the running process column) to "public".

    Failure to make both ports public will prevent the app from starting properly.

  10. Codespaces will suggest to open a new browser window or as a preview window

You can now use C# Hot Reload and XAML Hot Reload to develop your application.

See the VS Code Getting started documentation for additional details about developing with VS Code.

Creating your Codespace from scratch

If you want to start from an empty repository, follow these steps:

  1. Create an empty repository

  2. Install the unoplatform.vscode extension from the Extensions activity

  3. Open the command palette (Ctrl+Shift+P) and execute the Run uno-check command to install the appropriate .NET SDK

  4. Open the command palette (Ctrl+Shift+P) and run the Install the dotnet new templates command to install the dotnet new templates

  5. Open a terminal and create a new project using the following command:

    dotnetcli
    dotnet new unoapp -o MyApp -ios=false -android=false -macos=false -skia-tizen=false -skia-wpf=false -skia-linux-fb=false --vscode

  6. Using the Codespaces top left menu, open the MyApp folder

You're ready to develop for WebAssembly.
