You can do this for ASP.Net Core environment variable (ASPNETCORE_ENVIRONMENT): -

using Microsoft.AspNetCore.Hosting;
using System;

public class Program {
    private static string HostingEnvironment => Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
    private static bool IsEnvironment(string environmentName) => HostingEnvironment?.ToLower() == environmentName?.ToLower() && null != environmentName;

    private static bool Development => IsEnvironment(EnvironmentName.Development);
    private static bool Production => IsEnvironment(EnvironmentName.Production);
    private static bool Staging => IsEnvironment(EnvironmentName.Staging);

    public static void Main(string[] args) { // Your code here }
}

Then you can simply use the property

    public static void Main(string[] args) {
        if (Development){
            // Blow up the planet
        }
    }
