title: AutoMapper 5 when set CreateMissingTypeMaps true ForMember not work
body: <p>I think I found the cause of the problem, but I don't know how to solve it,
  the scene is like this:</p>
  
  <p>i used automapper 5.2 , Entity Framework 6 and use <code>CreateMissingTypeMaps=true</code> to save my CreateMap code
  and i also have special map, so Initialize code like this</p>
  
  <pre><code> Mapper.Initialize(
              a =&gt;
                  {
                      a.CreateMissingTypeMaps = true;
                      a.CreateMap&lt;query_template, QtGridUdfSearchTemplate&gt;()
                 .ForMember(dest =&gt; dest.GridId, opt =&gt; opt.MapFrom(src =&gt; src.GRID_ID))
                 .ForMember(dest =&gt; dest.Guid, opt =&gt; opt.MapFrom(src =&gt; src.QUERY_TEMPLATE_GUID))
                 .ForMember(dest =&gt; dest.TemplateName, opt =&gt; opt.MapFrom(src =&gt; src.TEMPLATE_NAME))
                 .ForMember(dest =&gt; dest.CreatedBy, opt =&gt; opt.MapFrom(src =&gt; src.CREATED_BY))
                 .ForMember(dest =&gt; dest.IsDefault, opt =&gt; opt.MapFrom(src =&gt; src.IS_DEFAULT))
                 .ForMember(dest =&gt; dest.IsOffset, opt =&gt; opt.MapFrom(src =&gt; src.IS_OFFSET));
                  }
           ); 
  </code></pre>
  
  <p>and map code </p>
  
  <pre><code> var source = DbContext.Set&lt;query_template&gt;().Find(keyValue);
   var dest = Mapper.Map&lt;query_template, QtGridUdfSearchTemplate&gt;(source);
  </code></pre>
  
  <p>i get the <code>dest</code> all attribute is null ,when i remove <code>a.CreateMissingTypeMaps = true;</code> in Initialize , it is work , the <code>dest</code> all attribute can be map.</p>
  
  <p>then i found the <code>source</code> Type is <code>System.Data.Entity.DynamicProxies.query_template_80DE6B32EB08D5DFDD560580BB004DAD6A7FF27B94A3517A6BB4044B01FB8272</code> , so i think when i set CreateMissingTypeMaps , autoMapper auto create a map , not my create </p>
  
  <p>many posts suggested <code>context.Configuration.ProxyCreationEnabled = false;</code> but i use LazyLoad. and don`t want to remove CreateMissingTypeMaps , because i have many normal type to map .</p>
  
  <p>anyone can help me ?</p>
