Summary

In this chapter, we began by introducing design principles. Following this, we delved into the SOLID design principles, and I shared insights gleaned from the development of our app. Among the most crucial SOLID principles is the DIP. DI is a technique that applies the DIP in practical implementation. In our app, we utilize the built-in DI service of .NET MAUI to decouple dependencies, enabling us to separate the implementation of the service from the interface.

We accumulated extensive knowledge about .NET MAUI and successfully completed our app implementation by replacing MockDataStore with the actual implementation. We established CRUD operations on top of this new IDataStore service, resulting in a fully functional password manager app.

Although we have incorporated essential features in our app, users often expect additional desirable features in a password manager application, such as fingerprint scanning and one-time passwords. Some of these features are platform...
