What do I do when ASP.NET 5 (vNext) can't redirect bindings?

I am just getting my feet wet with MVC 6. I installed VS 2015 and with the default ASP.NET 5 preview MVC Web Application template everything runs fine under local IIS.

I then tried to switch out the Default DI container with StructureMap following these instructions exactly (note it is a very recent article). The only thing is I had to figure out the namespaces to import myself (since the author neglected to include them) and this is what I included.

I put the StructureMapRegistration class and all related classes into a single file, and here are the usings.

using Microsoft.Framework.DependencyInjection;
using StructureMap;
using StructureMap.Configuration.DSL.Expressions;

I added the following usings to the Startup.cs file.

using StructureMap;
using StructureMap.Graph;
using System.Reflection;

And I made the following edit to the Startup.cs file.

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    // Add Entity Framework services to the services container.
    services.AddEntityFramework()
        .AddSqlServer()
        .AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"]));

    // Add Identity services to the services container.
    services.AddIdentity<ApplicationUser, IdentityRole>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();

    // Configure the options for the authentication middleware.
    // You can add options for Google, Twitter and other middleware as shown below.
    // For more information see http://go.microsoft.com/fwlink/?LinkID=532715
    services.Configure<FacebookAuthenticationOptions>(options =>
    {
        options.AppId = Configuration["Authentication:Facebook:AppId"];
        options.AppSecret = Configuration["Authentication:Facebook:AppSecret"];
    });

    services.Configure<MicrosoftAccountAuthenticationOptions>(options =>
    {
        options.ClientId = Configuration["Authentication:MicrosoftAccount:ClientId"];
        options.ClientSecret = Configuration["Authentication:MicrosoftAccount:ClientSecret"];
    });

    // Add MVC services to the services container.
    services.AddMvc();

    //// Uncomment the following line to add Web API services which makes it easier to port Web API 2 controllers.
    //// You will also need to add the Microsoft.AspNet.Mvc.WebApiCompatShim package to the 'dependencies' section of project.json.
    //// services.AddWebApiConventions();

    //// Register application services.
    //services.AddTransient<IEmailSender, AuthMessageSender>();
    //services.AddTransient<ISmsSender, AuthMessageSender>();

    var container = new Container();
    container.Configure(x =>
    {
        x.Scan(scanning =>
        {
            scanning.Assembly(Assembly.GetExecutingAssembly());
            scanning.TheCallingAssembly();
            scanning.WithDefaultConventions();
        });

        //x.AddRegistry<WebsiteRegistry>();
    });

    // Our framework extension point
    container.Populate(services);
}

Literally, the only things I have changed from the default template are the above code changes and installing StructureMap 3.1.6.186.

The using statements suppress all of the design time compilation errors, but when I build, I get several other errors.

The error indicates where the problem is - I need a reference to mscorlib 2.0.5.0. But I am already referencing mscorlib 4.0.0.0 in the project.

At this point in ASP.NET < 5, the next step would typically be to add some binding redirects to the <bindingRedirect> section of the web.config file. However, after searching for how to do this in ASP.NET 5, I came across this answer which indicates that binding redirection is supposed to be "totally automatic".

So is this a bug, or is there some step in my configuration that I missed that is resulting in this error?

What's your project.json look like and is this happening in IIS Express or IIS? – Dealdiane
@opiants - added to my answer. I have changed nothing from the default template except for the above code changes and adding StructureMap 3.1.6.186 as a dependency. The project doesn't even compile so I am pretty certain this has nothing to do with IIS Express. – NightOwl888
Have no experience with StructureMap itself but could it be that it doesn't support .NET Core yet? Even early-adopter DI containers are still in its very early stages. Anyway, try removing dnxcore50 in your frameworks in projects.json and see if it compiles or maybe try this nuget package instead or try both. – Dealdiane

Thanks to opiants, the problem appears to be related to the fact that the dnxcore50 framework was included in the project.

"frameworks": {
    "dnx451": { },
    "dnxcore50": { }
}

Removing it solved the issue.

"frameworks": {
    "dnx451": { }
}
