An old blog post that's still relevant about what the project does.
To set this up in your ASP.NET Core (or any OWIN-compatible framework really), add to your Startup:
app.UseOwin(m =>
{
m(Setup.Owin("/quartz/", () => Program.Scheduler));
Setup.Logger = new MemoryLogger(100, "/quartz/");
});
This repo also has a reference sample app.
