Exception when using Quartz with Topshelf

I am getting an error when trying to run Topshelf with Quartz

Topshelf.Hosts.ConsoleRunHost Error: 0 : An exception occurred, System.TypeLoadException: Could not load type 
'Quartz.Collection.HashSet`1' from assembly 'Quartz, Version=3.0.7.0, Culture=neutral, PublicKeyToken=*'.
   at Topshelf.Quartz.ScheduleJobServiceConfiguratorExtensions.<>c__DisplayClassa`1.<ConfigureJob>b__3()
   at Topshelf.Runtime.EventCallbackList`1.Notify(T data)
   at Topshelf.Builders.DelegateServiceBuilder`1.DelegateServiceHandle.Start(HostControl hostControl)
   at Topshelf.Hosts.ConsoleRunHost.Run()

My code is

HostFactory.Run(x =>
        {
            x.Service<Service>(s =>
            {
                s.WhenStarted(service => service.Start());
                s.WhenStopped(service => service.Stop());
                s.ConstructUsing(() => new Service());

                s.ScheduleQuartzJob(q =>
                    q.WithJob(() =>
                            JobBuilder.Create<Notifications>().Build())
                        .AddTrigger(() => TriggerBuilder.Create()
                            .WithSimpleSchedule(b => b.WithIntervalInSeconds(10)
                                .RepeatForever())
                            .Build()));
            });

            x.RunAsLocalSystem()
                .StartAutomatically();

            x.SetDescription("Quartz Service");
            x.SetDisplayName("QuartzService");
            x.SetServiceName("QuartzService");
        });

I can't seem to find anything in relation to Quartz.Collection.Hashset with a google search and i'm unsure how to go about getting it if it is missing.

The NuGet package that you are using is outdated. I ran into the exact error and had to write my own integration. If you are using dtnuget package on NuGet you are definitely going to have this problem; that package was last updated in the year 2015. Your best bet is to use a NuGet package published by bertuko. I have used his implementation as the base of my own, and it works fine.

I've put this down to the Quartz.Topshelf Nuget package not supporting .net core and had to resort to creating a windows service instead.

It appears you can do some very simple service creation with .net core 3.0 and above. So it renders Topshelf pretty much obselete. So this is defintely a better option.

Marking this as the answer unless this questions gets found by someone and they find a solution
