Validations: WebApi/ApplicationServices/DomainModel

In this session we will demonstrate how to properly implement validations from the WebApi to the Domain Model.

We will cover:
- Fail-fast validations
- CanExecute Pattern + Notification Pattern
- The ProblemDetails format (RFC 7807)
- Guard Clauses (design by contracts)

In addition, we will demystify the use of exceptions through Guard Clauses, and demonstrate why - once it is done right, throwing exceptions when needed is essential.

The event is scheduled for 7:00 PM, but if you want to arrive earlier, we will be there from 6:00 PM. Pizzas and drinks on us, as usual.

Address:
Av. Fontes Pereira de Melo, 16 (Idea Spaces). Room reflection.
