Hello, newby MEF here:
I have 2 interfaces to classlibraries I want to compose with my main application. What i am trying to achieve is a directory of .dlls that I can update/manage for the application as a whole.
public interface IObject1
public interface IObject2
Now in the main application thread, I get an error duplicate 'Import' attributes
. I want to use both objects in my main application, I just don't know how to import them properly.
#region Imports section
[Import(typeof(Object1), AllowRecomposition = true)]
[Import(typeof(Object2), AllowRecomposition = true)]
private Object1 _obj1;
private Object2 _obj2;
private void Compose()
dirCatalog = new DirectoryCatalog(@"D:\Folder");
AssemblyCatalog assemblyCat = new AssemblyCatalog(System.Reflection.Assembly.GetExecutingAssembly());
AggregateCatalog catalog = new AggregateCatalog(assemblyCat, dirCatalog);
CompositionContainer container = new CompositionContainer(catalog);
