Caliburn与Caliburn.Micro的区别及框架选型建议

Great question—since you’ve got hands-on experience with Prism + Unity and already know you love Caliburn’s convention-based auto-binding, let’s break down the key differences between these two frameworks and map them to your specific needs.

Core Differences Between Caliburn and Caliburn.Micro #

Size & Feature Scope #

• Full Caliburn: This is the heavier, more comprehensive framework. It comes packed with built-in tools like advanced screen/conductor patterns, robust dialog management, menu integration, and even Prism-style region support. It’s built for larger, more complex applications where you might need these extra features as your app scales.
• Caliburn.Micro: A lightweight, stripped-down subset of Caliburn. It focuses only on the essentials: the convention-based binding you’re drawn to, basic view-model lifecycle management, and minimal, optional DI/IOC support. It’s optimized for speed and simplicity, with zero bloat from features you won’t use.

Convention-Based Binding Capabilities #

Both frameworks offer auto-matching of properties/methods to view elements, but there’s a depth difference:

• Caliburn extends conventions to more complex UI elements (like data grids, custom controls, and nested menus), covering edge cases you might encounter in larger apps.
• Caliburn.Micro sticks to the core conventions that solve 90% of common use cases (e.g., binding a SaveCommand to a button named Save). It’s simpler and avoids overcomplicating basic binding scenarios.

DI/IOC Integration #

• Caliburn has a tightly integrated, full-featured DI system that works seamlessly with containers like Unity (which you’re familiar with). It also includes its own built-in container if you don’t want to use an external one.
• Caliburn.Micro’s DI support is intentionally minimal. Its built-in container is lightweight and optional—you can absolutely build your entire app without touching DI at all, which aligns perfectly with your current needs. If you ever decide to add DI later, it’s easy to swap in a container like Unity.

Regions & Navigation #

• Caliburn includes robust region support (similar to Prism) for complex UI composition—ideal for apps where you need to swap views in and out of designated areas.
• Caliburn.Micro doesn’t have built-in regions. It offers basic navigation via its simple Conductor pattern, but it’s designed to avoid the overhead of region management. Since you’ve stated you don’t need regions, this is a big plus for keeping your app lean.

Which Framework Should You Pick? #

Based on your scenario (small-to-medium WPF app, no immediate need for regions/DI, priority on convention-based binding):

Choose Caliburn.Micro if: #

• You want a lightweight, fast framework that adds minimal overhead to your project.
• You only need the core auto-binding feature without extra tools you won’t use right now.
• You want to avoid "feature creep" and keep your codebase focused on your app’s core functionality.
• You might want to add DI later but don’t need it today—its modular design makes integration easy down the line.

Choose Full Caliburn if: #

• You suspect your app might grow in complexity over time (even if it’s small now). If you think you’ll need advanced navigation, dialogs, or region support eventually, Caliburn gives you these tools upfront without needing to refactor later.
• You’re comfortable with heavier frameworks like Prism and don’t mind the extra feature set—Caliburn’s tools will feel familiar and give you more out-of-the-box capabilities.

Final Recommendation #

Given your current needs (no regions, no DI, small-to-medium app), Caliburn.Micro is the better fit. It delivers the exact auto-binding feature you love without the unnecessary bloat, and it’s straightforward to work with for simpler projects. That said, both frameworks are solid—if future-proofing for a larger app is a top concern, full Caliburn’s extra features won’t hurt, but they’ll add complexity you don’t need right now.
