App not starting with hangfire on Azure and dotnet 5

Hi,

I have a problem with Hangfire and dotnet 5 on Azure (Hangfire version: 1.7.18)

Here the Startup.cs file:

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddDbContextPool<EntitiesDb>(options =>
        {
            options.UseSqlServer(connectionString, sqlServerBuilder =>
            {
                sqlServerBuilder.UseNetTopologySuite();
            });
        });

        services.AddHangfire(configuration => configuration
            .SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
            .UseSimpleAssemblyNameTypeSerializer()
            .UseRecommendedSerializerSettings()
            .UseSqlServerStorage(Configuration.GetConnectionString("DefaultConnection"),
                new SqlServerStorageOptions()
                {
                    SchemaName = "hangfire",
                    PrepareSchemaIfNecessary = true,
                }));

        // Add the processing server as IHostedService
        if (Configuration["GlobalConfiguration:HangfireEnvironment"] == "Production" ||
            Configuration["GlobalConfiguration:HangfireEnvironment"] == "Preproduction")
        {
            services.AddHangfireServer();
        }
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env, GlobalConfiguration config)
    {
        app.UseHangfireDashboard("/hangfire", new DashboardOptions()
        {
            Authorization = new[] {new HangfireAuthorization()}
        });
    }
}

And the associated Program.cs:

public class Program
{
    public static void Main(string[] args)
    {
        IWebHostBuilder webHostBuilder = CreateWebHostBuilder(args);
        IWebHost webHost = webHostBuilder.Build();
        GlobalConfiguration.Configuration.UseActivator(new HangfireActivator(webHost.Services));

        using (var scope = webHost.Services.CreateScope())
        {
            var services = scope.ServiceProvider;
            services.GetRequiredService<ScheduledJobRunner>().ScheduleRecurrentJobs();
        }
        
        webHost.Run();
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseKestrel(options => options.Limits.MaxRequestBodySize = null) 
            .CaptureStartupErrors(true)
            .UseStartup<Startup>();
}

When I run this app locally I don’t have any problems, but on Azure I have the following error:

Application: w3wp.exe
CoreCLR Version: 5.0.20.51904

The ScheduledJobRunner class register diverse tasks on the provided IRecurringJobManager. But the implementation of IRecurringJobManager could not be found.

Anyone has encountered this error ?
Any help would be appreciated.

Thanks.
