.NET 6 Support

[tillig]

Includes:

• Adding net6.0 TFM to all projects.
• Updating test framework, analyzer, and other dev dependencies.
• Resolving new analyzer warnings, primarily:
  • Use the new operator to simplify object creation.
  • Pattern matching - x is not y instead of !(x is y), x is not null instead of x is object.
  • Marking things static that don't access instance data (really only in test fixtures).

A future PR can do some cleanup like setting up ImplicitUsings and file-scoped namespaces.

[tillig]

This PR supersedes #1300.

[alistairjevans]

Only 1 real thing that should change, that's the !(not null) check which can be simplified. The rest are mostly just thoughts, options, etc.

I'll try not to take the British English spelling removal too personally... 😂

The British English changes were either...

• 💯 personal attack - you want some, come get some! 😈 🤣
• standardization on US English because that's also what the API is in and it felt sort of weird to flip back and forth, especially in comments right above the API where the spellings conflicted.

I mean, you pick. Either way is cool 😉

[alistairjevans]

I have decided your spelling changes are not an attack on my Britishness, so we're tickety boo guv-ner!

[maulik-modi]

@alistairjevans or @tillig , When do you plan to publish Nuget package?

[tillig]

@maulik-modi Is there something here that your code requires? The existing package should work perfectly well with .NET 6.

[maulik-modi]

.net 6 being major version, may be breaking changes requiring new version of autofac. Get Outlook for Android<https://aka.ms/AAb9ysg>

There's are no breaking changes. Instead of guessing, try it out and let us know if there's something you find not working.
