Hangfire recurring job daily on specific time

Assuming you are using .Net Core, where you can find the file startup.cs. In that you can find a Configure() method. Inside the method you can use that piece of line right after app.UseHangfireDashboard() and app.UseHangfireServer() which is for configuring hangfire dashboard and this is optional. Don't forget to Register Hangfire Services in ConfigureServices() method which can be found in the startup.cs itself.

You can Register Hangfire Services inside ConfigureServices() in Startup.cs

    public void ConfigureServices(IServiceCollection services)
    {    
    /*
    other services
    */

    services.AddHangfire(x => x.UseSqlServerStorage("YOUR_HangfireServerConnectionString"));

    /*
    services.AddMvc()
    */
    }

You can Set Hangfire Cron inside Configure() in Startup.cs

public void Configure(IApplicationBuilder app)
{
    app.UseHangfireDashboard();  
    app.UseHangfireServer();
    RecurringJob.AddOrUpdate(() => MyMethod(), "* 9 * * *");
}

UPDATE

The cron expression * 9 * * * denotes that the job will fires every minutes after 9 (24 hour format) of system time UTC time.

For creating a recurring job at 9.00 AM Daily, the expression should be 0 9 * * * refer here cron expressions

In asp.net, you can add Microsoft.Owin Middleware and OwinStartup to your project via this nugetpackage and then use the startup.cs to setup hangfire. We always use the Configuration method of Startup.cs file for the hangfire recurring jobs:

            public void Configuration(IAppBuilder app) 
            {
                app.UseHangfireDashboard();
                app.UseHangfireServer();
                RecurringJob.AddOrUpdate(19872.ToString(),() => MyMethod(), Cron.Daily(9, 0));
            }
