GetPizzasAsync does not contain a definition

Question

I'm following the tutorial where this is step 4:

https://learn.microsoft.com/en-us/training/modules/interact-with-data-blazor-web-apps/4-access-data-from-blazor-components

There's a code section that shows this:

namespace BlazingPizza.Data;

public class PizzaService {

public Task

Hi Bill Mackin,

Thank you for reaching out to Microsoft Q & A forum.  

It appears that the issue with GetPizzasAsync() is due to a missing return statement, which results in the error message 'PizzaService.GetPizzasAsync()': not all code paths return a value. This happens because the code section in the tutorial includes a placeholder comment (// Call your data access technology here), but doesn’t include a complete example with a return statement 

To resolve this, you can add a temporary return value with some sample data. Here’s an example that will allow you to proceed without errors: 

public Task<Pizza[]> GetPizzasAsync()
{
    // Sample data to ensure the method compiles
    return Task.FromResult(new Pizza[]
    {
        new Pizza { PizzaId = 1, Name = "Margherita", Description = "Classic", Price = 9.99m, Vegetarian = true, Vegan = false },
        new Pizza { PizzaId = 2, Name = "Pepperoni", Description = "Spicy and savory", Price = 12.99m, Vegetarian = false, Vegan = false }
    });
}

This code provides placeholder pizza data, which can be replaced later with actual data from a database or other data source when you’re ready to integrate it.
