This issue only occurs in Visual Studio, not in Xamarin Studio.
When you open a storyboard or xib in iOS Designer, any Image Sets in the asset catalog will be picked up and will be selectable when clicking on the drop down for the Image property of a UIImage view. If you add a new Image Set to the Asset Catalog, the new image set will not be available in the drop down list for the Image property until you close and re-open the storyboard/xib. IN Xamarin Studio I do not need to close and re-open the storyboard/xib for the new image set to be available in the drop down.
## Steps to reproduce
1. Create a new iOS Single View app project in Visual Studio.
2. Create an asset catalog and add a new Image set and populate it with images.
3. Save the asset catalog.
4. Open the LaunchScreen.xib (created by default with the template... I would have though we would create a LaunchScreen.storyboard instead of an xib, but that is an issue for another bug report)
5. Drag an Image View to the View Controller and select it and view the properties.
6. Click on the Image property for the UIImageView in the properties pane. You should see the Image Set you created in step 2 in the drop down list.
7. Go back to the asset catalog and add a new Image Set and populate it with images.
8. Save the asset catalog.
9. Go back to the iOS Designer and select the image and click the Image property in the Properties pane.
Expected result: Will see the new image set created in step 7 in the drop down.
Actual result: I only see the image set created in step 2.
So it would appear that iOS designer is oblivious to changes in the asset catalog while a xib or storyboard is open, and only picks up the Image Sets that existed when the xib/storyboard was opened. I do note exactly the same behavior with a storyboard. Again this is Visual Studio only. All works as expected in Xamarin Studio.

Actually let's ignore this for now - i'm waiting on some additional information from our VS team before we can address this properly.

XVS adds ImageAssets with the `InProject` metadata attribute. VSM does not.
This causes two issues:
1) Projects created in VSM are not the same as projects created in VS.
2) Items with `InProject` set to false will not be accessible via the normal IVsHierarchy APIs and so will not trigger the ItemAdded/ItemRemoved events from `Dte.Events`.
* Use <Hidden>true</Hidden> instead of <InProject>false</InProject.
* Migrate old projects to the new system.
* Provide a custom API point which mimics the standard events, but only triggers for these explicitly excluded items
I'm open to anything ;)
Finally, we should make sure VSM follows the same conventions.
Sorry, the correct flag is `<Visible>False</Visible>`, not `<Hidden>true</Hidden>`. I always get that wrong ;)
Yes, i suspect the fact that ImageAsset items don't show up with the normal IVs events is the same reason why they don't show up in the normal IVSHierachy, which is why we still need the MSBuild hack to retrieve them.
I'm hoping we can remove the msbuild hack once the events work, as my hope is they will show up like normal items then!
I found another doc somewhere, but all I can find now is this: https://blogs.msdn.microsoft.com/jomo_fisher/2005/01/25/hack-the-build-hide-items-from-visual-studio-solution-explorer/#comment-2383
<InProject>false</InProject> might prevent something being included in the hierarchy, so we will need to remove that attribute. However just removing it might not be sufficient to make something be *in* the hierarchy. As it stands these items are still not showing up in the places they should be.
