@IEvangelist and @bradygaster, this sample will be ready for review next week after I add the Dockerfile

@IEvangelist, How do you feel about a floating version resolution?

<PackageReference Include="Microsoft.Orleans.Server" Version="8.*-*" />

That syntax should cover both pre-release and release variants of 8.x

I use this technique for Azure.AI.OpenAI over in our Cosmos+OpenAI sample:

@seesharprun - The 8.* works the exact same way, it will allow use to reference 8.0.0-rc.2 bits and when 8.0.0 happens it will resolve as that.
