Unable to instantiate in asp.net core 5.0 project

[jessicah]

Describe the bug services.AddRazorLight() doesn't appear sufficient to register types needed for DI to work.

To Reproduce Steps to reproduce the behavior:

services.AddRazorLight(() =>
{
    return new RazorLightEngineBuilder()
        .UseFileSystemProject("~/repo")
        .UseMemoryCachingProvider()
        .Build();
});

Expected behavior RazorLight dependencies registered and able to run project.

Information (please complete the following information):

• OS: Windows 10
• Platform: .NET Core 5.0 (ASP.NET Core)
• RazorLight: 2.0.0-beta9
• Are you using the OFFICIAL RazorLight package? Yes
• Visual Studio: Visual Studio Community 16.8.0 Preview 5.0

Additional context System.AggregateException: 'Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: RazorLight.IEngineHandler Lifetime: Singleton ImplementationType: RazorLight.EngineHandler': Unable to resolve service for type 'RazorLight.Compilation.IRazorTemplateCompiler' while attempting to activate 'RazorLight.EngineHandler'.)'

I managed to workaround the issue by hoisting the RazorEngine instance out of AddRazorLight(), then adding the following:

services.AddSingleton(new RazorLightOptions());
services.AddSingleton(razorEngine.Handler.Compiler);
services.AddSingleton(razorEngine.Handler.FactoryProvider);
services.AddSingleton(razorEngine.Handler.Cache);

But it would be nice to not have to do this... although now I'm blocked on https://github.com/toddams/RazorLight/issues/365, so I don't know if it's fully resolved yet.
