With CM 1.3 I get the following exception when trying to design xaml-view (with 1.2 everything is fine):
ArgumentNullExceptionwas thrown by Bootstrapper...
at Caliburn.Micro.Bootstrapper.StartDesignTime() in C:\Projects\Blue Spire\Caliburn.Micro\src\Caliburn.Micro.Silverlight\Bootstrapper.cs:line 49 at Caliburn.Micro.Bootstrapper`1..ctor()...
In my Configure() method I just do
var catalog = new AggregateCatalog(
SelectAssemblies().Select( x => new AssemblyCatalog( x ) ).OfType<ComposablePartCatalog>()
and so on...
Application is running, only design time seems to be failing
