Structure Map method Populate() doesn't work for ASP.NET Core

Question

According to StructureMap documentation and examples from StructureMap.Microsoft.DependencyInjection repository it has to work but it doesn't.

Here is my Startup class:

    public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();
        services.AddTransient<IMovieRepository, MovieRepository>();

        var container = new Container();
        container.Configure(config =>
        {
            config.AddRegistry(new MyRegistry());
            config.Populate(services);
        });

        return container.GetInstance<IServiceProvider>();
    }

And Registry:

public class MyRegistry : Registry
    {
        public MyRegistry()
        {
            For<IMovieRepository>().Transient().Use<MovieRepository>();
        }
    }

And here is error screenshot:

What's wrong with my code?

Did you add using StructureMap; to the top of the code file so you can call the Populate exension method? — NightOwl888

NightOwl888, of course I did add structure map name space, otherwise I wouldn't be able to create Container instance in the first place. — Serenkiy

You should also add the following nuget package to your project in order to use the Populate method of the Configuration option.

The package name: StructureMap.Microsoft.DependencyInjection

You do not have to import this library to the startup class though. "using StructureMap" there handles everything.

I decided to change IoC to Autofac. And the same problem appeared. I was following autofac documentation for asp.net core and skip a little detail. It took three days to figure out that I referenced to the wrong package. I referenced to the autofac package when what I was truly need was Autofac.Extensions.DependencyInjection package. It's ridiculous mistake that kick me off for a three days. I am truly convinced that the same kind of mistake I did with structure map, so just look for StructureMap.AspNetCore package instead of StructureMap package and everything will work.

!Read documentation extremely attentively!
