Run the (Blank) App

To run the app, we first need to run the backend GarphQL Server via the command line. Then we'll use Visual Studio to launch the app on an Android Emulator.

1. Start the GraphQL Backend Server​

  1. Open the Command Prompt (Windows) or the Terminal (macOS):

  2. In the command line, navigate to the downloaded code:

    cd [folder of downloaded code]/crypto-maui/backend/solutions/example8c/

    Note: Replace [folder of downloaded code] with the folder where you downloaded the source code for this workshop

  3. In the command line, enter the following command to run the Backend GraphQL Server:

    dotnet run --urls "http://localhost:5100"
caution

Keep the GraphQL Backend Server running in the background during the duration of the .NET MAUI workshop

info

If the .NET MAUI app fails to connect to the GraphQL API, ensure the Backend GraphQL Server is still running in the Terminal and its --urls parameter is set to http://localhost:5100

  1. In a browser, navigate to http://localhost:5100/graphql
  2. Confirm the GraphQL GUI appears Banana Cake Pop

2. Launch the .NET MAUI App​

  1. Locate the /fontend/0-Start/ folder:

    • (macOS) In Finder, navigate to the downloaded code: /crypto-maui/frontend/0-Start/
    • (Winodws) In File Explorer, navigate to the downloaded code: /crypto-maui/frontend/0-Start/

  2. In the /fontend/0-Start/ folder, open MauiCrypto.sln in Visual Studio

  3. In Visual Studio, set the build target to Android:

    macOS​

    In the Visual Studio for Mac toolbar, ensure the build is pointing to your Android Emulator
