Hello, I am currently writing a framework dll which has an AssemblyHelper. This helper stores Runtime and UserAdded assemblies to easily instantiate new objects. The .NET part of the framework uses: AppDomain MyDomain = AppDomain.CurrentDomain; Assembly[] AssembliesLoaded = MyDomain.GetAssemblies(); _runtimeAssemblies = AssembliesLoaded; This gets me all the assemblies I need. But the problem is I can't use this with Silverlight and I have no idea what to use now. Currently I am using: Assembly[] AssembliesLoaded = {Assembly.GetCallingAssembly()}; But this only adds the Assembly of my framework and not the one of the application or any other runtime assembly. What should I use? please help! Thanks in advance, Wouter
