Currently, if you make certain changes to Data Structures, in this instance, removing, then adding a Data Property of the exact same Name and Type, the Stage will not update until after the application is completely restarted. This one is a bit hard to explain, the repro steps will make this more clear:

Repro Steps:

1) Open the Alembic Sample from the InternalProjects GitHub.
2) Ensure you have a Fork/SourceControl system hooked up to the InternalProjects GitHub Alembic Project, as this will be required in the next steps.

3) With Alembic open in Studio, observe on the Page, that each row has a section with three ingredient icons displayed.

4) Navigate to the Data Panel, and under the 'CraftItem' Data Structure, delete the three Properties: Ingredient1, Ingredient2, and Ingredient3.
Observe how the three ingredients identified in Step 3) have disappeared as expected.

5) In the Data Panel, under the 'CraftItem' Data Structure, add the three following Properties:

• 'Ingredient1' of Type 'Alembic.Ingredient' as a Single.
• 'Ingredient2' of Type 'Alembic.Ingredient' as a Single.
• 'Ingredient3' of Type 'Alembic.Ingredient' as a Single.

6) In Fork/SourceControl, observe how have been changed:
AlembicDataSet.xaml
Craftitem.xaml

7) In Fork, Discard the changes made to AlembicDataSet.xaml
This, in theory, brings us exactly back to the state of the UI when we opened the project: no changes made to the AlembicDataSet, and the CraftItem.xaml changes actually represent no changes, as what was removed, has been re-added back exactly as-was.

8) Within Studio, observe how the ingredient icons on the Page are not displayed despite all of the Bindings still being valid, and the Data all reflecting a state where it previously worked.

9) Close MainPage.xaml and re-open it.
Observe how the icons have still not been made visible.

10) Close Studio, and re-open the Alembic Project.
Observe how this time, the icons are successfully displaying as expected.

Expected Results: Valid changes to Data are immediately detected and displayed on-Stage.
