This article is a general recommendation for setting up data on startup. This can be useful when bootstrapping a project and setting up Data Types, Definitions, and other entities.
When to create the data?
We recommend placing the logic for creating data into a HostedService. By inheriting BackgroundService, you create a potentially long-running job activated once at app startup.
Create the Service
public class SetupData : BackgroundService
{
private readonly IServiceProvider _serviceProvider;
public SetupData(IServiceProvider serviceProvider)
{
_serviceProvider = serviceProvider;
}
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
await using var asyncScope = _serviceProvider.CreateAsyncScope();
var dbContext = asyncScope.ServiceProvider.GetRequiredService<UcommerceDbContext>();
// Set up data using dbContext
await dbContext.SaveChangesAsync(stoppingToken);
}
}
