如何每隔 X 小时自动调用 ASP.NET Core 端点？

Question

I've build an API with ASP.NET Core. Some of my controllers have an endpoint, which need to run each X hours. Nevertheless I still want to be able to call the endpoint by my own at any time.

The endpoints all have the same structure:

[RequireHttps, HttpGet("/generate")]
public async Task<IActionResult> GenerateFiles()
{
    // do stuff 
}

Does anybody know how I could achieve this in ASP.NET Core itself without any third-party tool? I thought of using a timer, but I feel like this is not the best way to do so. I highly appreciate any kind of help, cheers: :)

With Hangfire that's quite easy to do:

Inside the Program.cs/Startup.cs:

builder.Services
    .AddHangfire(opts => opts
        .UseSqlServerStorage(config
            .GetSection(nameof(HangfireConfig))
            .Get<HangfireConfig>()
            .ConnectionString)
        .AddUpdateJob(builder.Environment))
    .AddHangfireServer()

And AddUpdateJob() is implemented like this:

public static IGlobalConfiguration AddUpdateJob(
    this IGlobalConfiguration opts,
    IWebHostEnvironment env)
{
    if (!env.IsEnvironment("Local"))
    {
        RecurringJob.AddOrUpdate<IMasterDataUpdater>(
            "masterdata-update",
            x => x.Update(),
            Cron.Hourly);
    }

    return otps;
}
