Solutions

1. Add a constructor matching the instantiation arguments on the target type.
2. Ensure the selected aliases match the constructor parameters.

When it happens

Trigger: A dynamic instantiation (select new) target cannot be constructed.

Common situations: Using 'select new SomeClass(...)' where the class is missing or has no matching constructor.
