You may want to review the last paragraph before you started in on the steps. Looks like you rewrote that sentence a few times, and left bits and pieces of old versions in there. It doesn't make sense now. :(

As an example of when you would want to use AllowMultiple = true, check this out.

[MetadataAttribute]

[AttributeUsages(AttributeTargets.Class, AllowMultiple=true)]

public class CategoryMetadata : Attribute {

public string Category {get;set;}

}

The importer for this export would need to have an array, otherwise the exporter would not be matched as we use type as part of the matching and array of string is different than string.

public interface ICategoryView {

public string[] Category {get;}

}

Nice post, and Yes I here :-)

If you don't set AllowMultiple to false, MEF will assume there can be multiple metadata values for each key. As a result it will make the metadata values arrays which will be incompatible with your metadata view unless it's values are also arrays.

There are cases where having multiple values makes sense such as if you have multiple categories. In general in these cases you would probably have a free-form metadata attribute (decorated with MetadataAttribute) which is not an export. This would be annotated on top of an existing export.

I had the same issue. I had to alter the MSbuild WebApplication file located: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications and remove these entries.

Retries="$(CopyRetryCount)"

and RetryDelayMilliseconds="$(CopyRetryDelayMilliseconds)"

Once both of these were removed (in 13 places) everything worked fine. Hope it helps you too.

re: Noisy code does not equal clean code

@Matt,

Oh I know i could submit patch, but not sure my 'concepts' are what everyone is looking for.

And again using Automapper in this post was ONLY to talk about noisy code, not a reflection on the library.

Also, and I don't know what they do now, but some dynamic proxy libraries, at one point, did not return the proxied type from GetType(), but rather the proxy type.. I think that's why the explicit call is there.

You can always take a dependency on IMappingEngine, or decorate it to add the behavior you want. Also, AutoMapper is on github and is accepting contributions.

Noisy codes seriously bother me! Makes me want to go and change it for them, but of course I need to get paid.

@Eber, @Alberto

RhinoMocks adds an extension method to object. It would only cause chaos, if you were to call it that, if you were to use every library in the world in your project that does this.
