You can get a list of loaded assemblies by using this:

Assembly assembly = System.Reflection.AppDomain.CurrentDomain.GetAssemblies()

From there, you can get a list of types in the assembly (assuming public types):

Type[] types = assembly.GetExportedTypes();

Then you can ask each type whether it supports that interface by finding that interface on the object:

Type interfaceType = type.GetInterface("ISomething");

Not sure if there is a more efficient way of doing this with reflection.
