结构图方法Populate（）对ASP.NET Core不起作用

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?

Answer 1

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.

Answer 2

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!
