 - Remove the version from the PackageId PackageReference.
 - You may need to add or update the PackageVersion item for PackageId in Directory.Packages.props
 
-Example:
+    Example:
 
-```xml
-<!-- In the project file. -->
-<PackageReference Include="PackageId" />
-```
+    ```xml
+    <!-- In the project file. -->
+    <PackageReference Include="PackageId" />

+    <!-- In the Directory.Packages.props -->
+    <PackageVersion Include="PackageId" Version="5.1.0" />
+    ```
+
+- Alternatively, you may override an individual package version by using the `VersionOverride` property on a `<PackageReference />` item.
+This overrides any `<PackageVersion />` defined centrally.
+
+    Example:
+
+    ```xml
+    <!-- In the project file. -->
+    <PackageReference Include="PackageId" VersionOverride="3.0.0" />
+    ```
+
+    ```xml
+    <!-- In the Directory.Packages.props -->
+    <PackageVersion Include="PackageId" Version="5.1.0" />
+    ```
 
-```xml
-<!-- In the Directory.Packages.props -->
-<PackageVersion Include="PackageId" Version="5.1.0" />
-```
