c# - How to get the Development/Staging/production Hosting Environment in ConfigureServices

Question

How do I get the Development/Staging/production Hosting Environment in the ConfigureServices method in Startup?

public void ConfigureServices(IServiceCollection services)
{
    // Which environment are we running under?
}

The ConfigureServices method only takes a single IServiceCollection parameter.

You can easily access it in ConfigureServices, just persist it to a property during Startup method which is called first and gets it passed in, then you can access the property from ConfigureServices.

public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv)
{
    ...your code here...
    CurrentEnvironment = env;
}

private IHostingEnvironment CurrentEnvironment{ get; set; } 

public void ConfigureServices(IServiceCollection services)
{
    string envName = CurrentEnvironment.EnvironmentName;
    ... your code here...
}
