tye ignores ASPNETCORE_ENVIRONMENT?

Describe the bug

A clear and concise description of what the bug is.

tye always ignores the ASPNETCORE_ENVIRONMENT variable and selects the DOTNET_ENVIRONMENT instead.

To Reproduce

env:
      - name: ASPNETCORE_ENVIRONMENT
        value: docker

But here is what I get.

We are seeing similar behaviour;
When upgrading an ASP.NET 6.0 application to 7.0 we see that setting ASPNETCORE_ENVIRONMENT from tye.yaml no longer works, but setting DOTNET_ENVIRONMENT does work as expected.
Unclear if this is a bug in Tye or a change in .Net 7

[thijsk]

It is a breaking change in .NET 7.
The environment variable precedence has changed: https://learn.microsoft.com/en-us/dotnet/core/compatibility/aspnet-core/7.0/environment-variable-precedence

And since tye sets both by default

tye/src/Microsoft.Tye.Hosting/ProcessRunner.cs

Line 202 in 7546561

["DOTNET_ENVIRONMENT"] = "Development",

you'll have to specify DOTNET_ENVIRONMENT in your configuration instead of ASPNETCORE_ENVIRONMENT

Looks like a real change in the environment variable name in .NET
