signed version of structuemap 4.5.3 in webapi 2.0 project. compile error -'CreatePluginFamilyExpr

[stev...@mail.com]

I am using a signed version of structuemap 4.5.3 in a webapi 2.0 project.

I am getting the following compile error on the following piece of code.

For<ISpaceRadarDbContext>()

                        .HttpContextScoped()

                        .Use(c => new SpaceRadarDbContext());

The error below saids something 'CreatePluginFamilyExpression<>' is defined in an assembly that is not referenced 

How do Fix this?

using SpaceRadar.Context;

using SpaceRadar.Repositories;

using SpaceWeather.Log;

using StructureMap;

using StructureMap.Web;

namespace SpaceRadar.Web.Api.DependencyResolution

{

    public class LogRegistry : Registry

    {

        public LogRegistry()

        {

            For<ISpaceWeatherLogService>().AlwaysUnique().Use(s => s.ParentType == null ? new SpaceWeatherLogService(s.GetType()) : new SpaceWeatherLogService(s.ParentType));

            For<ISpaceRadarDbContext>()

                        .HttpContextScoped()

                        .Use(c => new SpaceRadarDbContext());

        }

    }

I think you’re getting a binding conflict. I’m guessing you’ve got the StructureMap.Web nuget package in there somewhere? That apparently references StructureMap 4.0.0, so when you call HttpContextScoped(), you get the blowup.

In case you wondering, this exact kind of scenario is why I refuse to sign StructureMap.

You might try a binding redirect from 4.0 to 4.5.3 to get around that. If you’re using Web API though, do you even need the HttpContextScoped() thing? If you’re using a nested container per request, that should no longer be necessary.
