PostSharp and StructureMap

Question

So I was reading this fun article from Dustin Davis and decided to try it on my own with PostSharp 2.1.7.30 and StructureMap 2.6.4.1.

using System;
using PostSharp.Aspects;

namespace StructureMap
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            ObjectFactory.Initialize(x => { 
                x.For(typeof (IDbFind)).Use(typeof (DbFind)); });
            var w = new Worker();
            var f = w.Finder;
        }
    }

    internal class Worker
    {
        [IoCResolution] private IDbFind finder;
        public IDbFind Finder
        {
            get { return finder; }
        }
    }

    internal class DbFind : IDbFind
    {
    }

    internal interface IDbFind
    {
    }

    [Serializable]
    public class IoCResolution : LocationInterceptionAspect
    {
        public override void OnGetValue(LocationInterceptionArgs args)
        {
            args.ProceedGetValue();
            if (args.Value == null)
            {
                object obj = ObjectFactory.GetInstance(
                    args.Location.PropertyInfo.PropertyType);
                args.Value = obj;
                args.ProceedSetValue();
            }
        }
    }
}

Unfortunately during execution I get this error:

{"The type initializer for '<>z__Aspects' threw an exception."}

With an Inner Exception of:

{"Could not load file or assembly 'StructureMap, Version=1.0.0.0, 
Culture=neutral, PublicKeyToken=null' or one of its dependencies. The 
located assembly's manifest definition does not match the assembly reference. 
(Exception from HRESULT: 0x80131040)":"StructureMap, Version=1.0.0.0, 
Culture=neutral, PublicKeyToken=null"}

Any ideas what I could be doing wrong?

UPDATE 5 minutes later: I'm an idiot ... This will teach me not to call my namespace the same as a 3rd party DLL. After changing namespace to StructureMapPlay, it works just fine.

Answer 1

Change the namespace to StructureMapPlay, in code and project properties.
