What is WpfAppFetchingApiDataExample?

WpfAppFetchingApiDataExample is an example of how a .NET WPF app can fetch data from an ASP.NET Web API and display it.

The .NET solution contains four projects, which include:

• ASP.NET Web API, based on the weather forecast project included with Visual Studio as a template.
• .NET WPF app to display the dummy weather forecast data from the API, using DI, MVVM and XAML.
• Class library for the WPF app.
• Class library for data access.

NOTE: Exception handling, resilient HTTP calls, proper logging etc, have been omitted on purpose to simplify this example.

Setup instructions

1. Clone the WpfAppFetchingApiDataExample repository.

2. Open the .NET solution in Visual Studio 2022 (or a compatible alternative).

3. Set both WpfApiDataExample.DataManager.Api and WpfApiDataExample.UI.Wpf as startup projects.

4. Build the solution and run.

5. The API should open in a web browser window. Make a note of the URL, and stop the app.

6. Open appsettings.json in WpfApiDataExample.UI.Wpf and update ApiBaseUrl with the URL from the previous step.

7. Build the solution and run.

8. The API should open in a web browser and also the WPF app should open displaying the weather forecast.
