Why do environmentVariables from launchSettings.json profiles not load when aspNetCore web.config sections exist?

We recently upgraded a .NET Core 2.1 Web App to .NET 3.1. Ever since, our profiles in launchSettings.json are not properly working. Specifically, the environmentVariables are not loading, with one in particular being “ASPNETCORE_ENVIRONMENT”. We use this to switch appSettings.{Environment}.json when debugging locally to target different environments.

Deploy Unity3D in Windows Azure

I’m a bit stuck with the windows Azure plateforme. For now, I have a ASP.NET MVC 3 Web role running on Azure. But I want to deploy a Unity3D Web Player Application. How can I perform this task. I think it’s quite the same if I want to deploy a flash application on a web page. Instead of a .swf file, I have a .unity3d file.
Did somebody performed some kind of thing ?
