+### A pluarlizer is now included for scaffolding reverse engineered models
+
+[Tracking Issue #11160](https://github.com/dotnet/efcore/issues/11160)
+
+**Old behavior**
+
+Previously, you had to install a separate pluralizer package in order to pluralize DbSet and collection navigation names and singularize table names when scaffoding a DbContext and entity types by reverse engineering a database schema.
+
+**New behavior**
+
+EF Core now includes a pluralizer that uses the [Humanizer](https://github.com/Humanizr/Humanizer) library. This is the same library Visual Studio uses to recommend variable names.
+
+**Why**
+
+Using plural forms of words for collection properties and singular forms for types and reference properties is idiomatic in .NET.
+
+**Mitigations**
+
+To disable the pluralizer, use the `--no-pluralize` option on `dotnet ef dbcontext scaffold` or the `-NoPluralize` switch on `Scaffold-DbContext`.
