How to Access the Hosting Environment in ConfigureServices

It can be useful to run different services in Development vs Production. The .NET Core templates do this within certain methods, such as the Configure method in the Startup class but there is no example of how to do it in the ConfigureServices method within the Startup Class. The ConfigureServices method is where you often do a majority of additions.

Fortunately for us, the answer is simple. You can add it to your Startup constructor: public Startup(IConfiguration configuration, IHostingEnvironment environment). This will inject an IHostingEnvironment that you can set as a property available to any Startup method.

public class Startup
    public Startup(IConfiguration configuration, IHostingEnvironment environment)
        Configuration = configuration;
        HostingEnvironment = environment;

    public IConfiguration Configuration { get; }
    public IHostingEnvironment HostingEnvironment { get; }

    public void ConfigureServices(IServiceCollection services)
        if (HostingEnvironment.IsDevelopment())

One Last Thing...
