How to add Hangfire as service with custom configuration on asp.net core

Question

I wan't to add some configuration to hangfire. It's easy going the documented way but there is one option that depends on User setting so I wan't to do it like this:

IGlobalConfiguration hangfireConfiguration = GlobalConfiguration.Configuration
    .SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
    .UseSimpleAssemblyNameTypeSerializer()
    .UseRecommendedSerializerSettings();

 if (Configuration.GetValue<bool>("HangfireUseMemoryStorage"))
 {
    hangfireConfiguration.UseMemoryStorage();
 }
    else
 {
    hangfireConfiguration.UseStorage(new MySqlStorage(
        Configuration.GetConnectionString("DefaultConnection"),
        new MySqlStorageOptions
        {
            TablesPrefix = "Hangfire"
        })
    );
};

But how to add a service with this configuration? Trying

services.AddHangfire(hangfireConfiguration);

leads to

cannot convert from 'Hangfire.IGlobalConfiguration' to 'System.Action<Hangfire.IGlobalConfiguration>'

So how can I add my configuration?

If you want to define the hangfire configuration, you will need to add it like this,

Taken from Hangfire Docs

Hangfire 1.7 Release Docs

// Add Hangfire services.
    services.AddHangfire(configuration => configuration
        .SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
        .UseSimpleAssemblyNameTypeSerializer()
        .UseRecommendedSerializerSettings()
        .UseSqlServerStorage(Configuration.GetConnectionString("HangfireConnection"), new SqlServerStorageOptions
        {
            CommandBatchMaxTimeout = TimeSpan.FromMinutes(5),
            SlidingInvisibilityTimeout = TimeSpan.FromMinutes(5),
            QueuePollInterval = TimeSpan.Zero,
            UseRecommendedIsolationLevel = true,
            DisableGlobalLocks = true
        }));

    // Add the processing server as IHostedService
    services.AddHangfireServer();

You can add the if/else on which storage to use based on Configuration.GetValue<bool>("HangfireUseMemoryStorage")

But in this case I would have to duplicate the other settings.

Hangfire Documentation ... I would suggest checking section 6.1.6 and 6.1.7. In ASP.NET Core environments global configuration class is hidden inside the AddHangfire method
