I get this error :

![file](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/A7K4LbV7pX0Z-legacy-files-WUyWWG0CMP5FHvFL-hW1oyzPqHLfu-fWCjFMSeSo8.png)

When i try this

```auto
<App>
    <NativeViewHost>
        <MapView/>
    </NativeViewHost>
</App>

```

I run with the newest version 0.24 and my old projects works 🙂

Did you remember to add a package reference to Fuse.Maps in your unoproj?

Its not your fault at all. I see the documentation is a bit unclear on this point. Will make sure that gets fixed.

Glad it worked out 🙂

Super! Now the only thing which missing in the MapView is the ability to set custom markers … I hope you’re working on it! 🙂

  	"Fuse.Maps",
  	"Fuse.Controls"
