+                    Must iterate through assemblies individually and handle
+                    ReflectionTypeLoadException because some assemblies contain
+                    types that cannot be loaded (e.g., SqlGuidCaster from
+                    Microsoft.Data.SqlClient), causing GetTypes() to fail. When
+                    the exception occurs, use the Types collection from the
+                    exception which contains the types that were successfully
+                    loaded (with $null entries for failed types).
