Question 1

Is Realm .NET still a good choice after the sync deprecation?

Accepted Answer

Yes, for local data storage without sync, Realm remains a performant option. Install version 20 or use the community branch to avoid sync features, but for new projects needing real-time sync, consider alternatives like Firebase or custom solutions.

Question 2

How does Realm compare to SQLite for .NET mobile apps?

Accepted Answer

Realm offers an object-oriented API and claims higher performance than SQLite, but SQLite has a larger ecosystem and is more widely supported. Realm is better for apps wanting a modern, code-first approach without ORM complexity.

Question 3

How to migrate from Realm with sync to another database?

Accepted Answer

MongoDB provides deprecation guides for data migration. Generally, export data from Realm files and import into another system like SQLite or a cloud database, then update your app's data layer code accordingly.

Question 4

Can I use Realm for desktop applications on Windows or macOS?

Accepted Answer

Yes, Realm supports desktop OSes like Windows, macOS, and Linux, making it suitable for cross-platform .NET applications beyond mobile devices, as noted in the platform compatibility section.

Question 5

What are the best practices for using Realm with MVVM in MAUI?

Accepted Answer

The README includes examples like QuickJournal, which demonstrates integrating Realm with MVVM and data binding in MAUI apps. Use Realm's object notifications for reactive UI updates and keep business logic separate.

Question 6

Are there performance benchmarks for Realm vs Entity Framework?

Accepted Answer

Realm benchmarks often compare to SQLite, not Entity Framework directly. However, Realm's mobile-first design aims for better performance on devices, but you should test with your specific use case for accurate comparisons.
