Where to register a RegionBehavior when using Forms?

[jameslavery]

I need to add a Region Behavior to dispose of Views and ViewModels when the Region closes them.

I've worked out how to code the Behavior itself, but all references to Region Behaviors mention overriding the Bootstrapper's ConfigureDefaultRegionBehaviors method to add the Behavior.

However, I can't find a Bootstrapper class to override. Is this available in Prism.Forms?

I'm using:

• Prism.DryIoc.Forms 8.0.0.1909
• Prism.Forms.Regions 8.0.0.1909

Or is there another way to achieve this without a RegionBehavior?

@brianlagunas thanks - but that refers to Page Behaviors. I need to add a Region Behavior. Can I use the same pattern to apply my Region Behavior with a RegionBehaviorFactory?

[brianlagunas]

Oh sorry, I'm replying from my phone and missed that part. You'd probably have to resolve the IRegionBehaviorFactory and add your region behaviors to it.

However, I'm pretty sure the regions implement IDestructible already. Why not just use that?

Great - thank you. I was going to go down the path of resolving IRegionBehaviorFactory, so shows I was on the right path. Equally, as you say, it looks like you've already got IDestructibleRegionBehavior, so it should 'just work'. I need to investigate more!
