+# Enhanced Bulk Update and Delete
+
+EF Core has always required that Bulk Updates and Deletes be performed on a single table.  However, when using Owned Entities, the data is in a single table, but EF Core still wouldn't allow you to perform a Bulk Update or Delete.
+
+## Use Cases
+
+- Bulk Update and Delete on Owned Entities
+
+## Resources
+
+- [EF Core Docs | Enhanced Bulk Updates and Deletes](https://learn.microsoft.com/en-us/ef/core/what-is-new/ef-core-8.0/whatsnew#better-executeupdate-and-executedelete)
