+- **`--use-current-runtime, --ucr [true|false]`**
+
+  Sets the `RuntimeIdentifier` to a platform portable `RuntimeIdentifier` based on the one of your machine. This happens implicitly with properties that require a `RuntimeIdentifier`, such as `SelfContained`, `PublishAot`, `PublishSelfContained`, `PublishSingleFile`, and `PublishReadyToRun`. If the property is set to false, that implicit resolution will no longer occur.
+
 - **`--version-suffix <VERSION_SUFFIX>`**
 
   Defines the version suffix to replace the asterisk (`*`) in the version field of the project file.
