Missing instructions

Are there any instructions on how to run this? I have no clue on how to do it. Which ones to run first. Can i run them with powershell and dotnet run command?

Build errors

Hi, thanx for the example.
I use VS2019 (Version 16.2.0 Preview 2.0), I have tried to build the solution and receive the errors:

1>C:\Program Files\dotnet\sdk\3.0.100-preview4-011223\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.RuntimeIdentifierInference.targets(151,5): message NETSDK1057: You are using a preview version of .NET Core. See: https://aka.ms/dotnet-core-preview

How to fix the errors?

Thread safety bugs, null ref, code quality

Feedback from David Fowler

'That’s not super clean. I have a bunch of comments (including the lack on thread safety in a bunch of places). That null ref also looks like an HttpContext being used after it’s been recycled (which is bad).'
