dynamic type
Pros: This approach reduces the need to modify static ViewModel classes whenever you update the SQL sentence of a query, making this design approach pretty agile when coding, straightforward, and quick to evolve in regard to future changes.
Cons: In the long term, dynamic types can negatively impact the clarity and the compatibility of a service with client apps. In addition, middleware software like Swashbuckle cannot provide the same level of documentation on returned types if using dynamic types.
ViewModel (DTO)
Pros : Having static predefined ViewModel classes, like “contracts” based on explicit DTO classes, is definitely better for public APIs but also for long term microservices, even if they are only used by the same application.
If you want to specify response types for Swagger, you need to use explicit DTO classes as the return type. Therefore, predefined DTO classes allow you to offer richer information from Swagger. That improves the API documentation and compatibility when consuming an API.
Cons : As mentioned earlier, when updating the code, it takes some more steps to update the DTO classes.
