Suggested Answer:

The AppDomain.CurrentDomain.GetAssemblies() gives you all assemblies loaded in the current application domain.
The Assembly class provides a GetTypes() method to retrieve all types within that particular assembly.
Example: Using Linq:
IEnumerable<Type> types =
from a in AppDomain.CurrentDomain.GetAssemblies()
from t in a.GetTypes()
select t;

I tried 1,5 & 2 but I got compilation error with SelectMany. List<Type> types = (AppDomain.CurrentDomain.GetAssemblies() .SelectMany(t => t.GetType()) .Where(t => t.IsClass && t.Assembly == this.GetType().Assembly)).ToList<Type>(); But with 1,4 & 2 works without error.

The answer should be AppDomian Select Assembly This compiles without error List<Type> types = (AppDomain.CurrentDomain.GetAssemblies().Select(t => t.GetType()) .Where(t => t.IsClass && t.Assembly == t.GetType().Assembly)).ToList<Type>();
