thnx, the solution with Ref worked,
also "Discovering Modules in a Directory" worked,
except for on Module called LogModule, if i copy it's binaries into the Module Catalog, when starting app I get this error:
Could not load file or assembly 'Microsoft.Windows.Design.Extensibility, Version=188.8.131.52, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
even tough the Module doesn't references this library, and if I reference it, it will tell me that it doesn't has a subnamespace
here you can see all the referenced libraries: http://tinypic.com/r/a40c3o/5
