Get list of all assemblies in application in a Core 2.0 application RRS feed

  • Question

  • I'm working on a Core 2.0 back-end solution. I want to use the Core DI container. I have a class in each project that handles the registrations.  This is the code that I use to find all these bootstrap classes. 

                var assemblies = AppDomain.CurrentDomain.GetAssemblies().Where(x => x.GetName().FullName.StartsWith("MyCorp."));
                var bootstrapperTypes =
                    .SelectMany(x => x.GetTypes().Where(y => y.GetInterfaces().Contains(typeof(IBootstrapper))))

    However not all referenced assemblies are retruned by this code. I if no classes have been hit in the assebly, it is not returned.
    What do I need to do, to get a complete list in a reliable fashion?

  • .Net Cor can be discussed at ASP.NET forums that has a Core forum.

  • Consider Assembly.GetExecutingAssembly().GetReferencedAssemblies(). Also, try calling GetReferencedAssemblies for other assemblies returned by GetAssemblies. If you need information for assemblies that were not loaded yet, then consider Assembly.ReflectionOnlyLoad.

    Well do you see a MSDN .NET Core forum anywhere? At least in the ASP.NET Core forum, you at least have developers working with Core that can possibly help you.

  • Assembly.GetExecutingAssembly() did not do the trick. The statement is executed in the helper class that filters the assemblies. The helper is not in the top level assembly glueing the application together.

  • Hi ksighem,

    For your question try to use Module.FindTypes.

      static Type[] test(Assembly ass)
                return ass.GetModules()[0].FindTypes((type, obj) => type.Name.StartsWith("MyCorp"), null);
