NET6 and IServiceProviderIsService support.

[alistairjevans]

Raising a PR to bring this in now the builds are passing, and .NET 6 Preview 6 has been released with IServiceProviderIsService available.

I've made AutofacServiceProvider a partial class, and put the .NET 6 specific service on a partial in it's own file. Seemed like the cleanest way to add it.

All the new specific tests added by the dotnet team that validate this new behaviour are passing.

I figured out the problem with VS Code - OmniSharp only looks at the first item in TargetFrameworks and generates issues and Intellisense based on that. I've moved the .NET 6 framework (and conditional references) to be encountered first in the projects and it's resolved all the weird "error being displayed but it compiles just fine" problems.

Since this seems to be high visibility would it be worth putting a beta out on NuGet for folks to try?

[alistairjevans]

Seems like a good idea.

Assuming you mean pushing 7.2.0-develop-00520 from MyGet to NuGet as 7.2.0-preview.1 or something?

[tillig]

Exactly that. I can take care of it later if you don't have time, either way.

[alistairjevans]

I'll push it later, should only take a minute. I'll raise a GitHub preview release for it as well.

[alistairjevans]

Nuget package pushed, I'll post on that original runtime thread that it's available.
