+## Description
+
+I upgraded my Telerik Reporting project, which uses the [Blazor Native Viewer]({%slug telerikreporting/embedding-reports/display-reports-in-applications/web-application/native-blazor-report-viewer/overview%}). After the upgrade, I encountered the following error:
+
+````
+System.InvalidOperationException: Object of type 'Telerik.Blazor.Components.TelerikWindow' does not have a property matching the name 'Centered'.
+   at Microsoft.AspNetCore.Components.Reflection.ComponentProperties.ThrowForUnknownIncomingParameterName(Type targetType, String parameterName)
+   at Microsoft.AspNetCore.Components.Reflection.ComponentProperties.SetProperties(ParameterView& parameters, Object target)
+   at Telerik.Blazor.Components.TelerikWindow.SetParametersAsync(ParameterView parameters)
+   at Microsoft.AspNetCore.Components.Rendering.ComponentState.SupplyCombinedParameters(ParameterView directAndCascadingParameters)
+````
+
+This error occurs because the Blazor Native Viewer depends on version `7.1.0` of the Telerik UI for Blazor components and tries to access the `Centered` parameter of the TelerikWindow component. This parameter was removed in version `9.0.0`. Compatibility issues arise due to the dependency mismatch.
+
+## Solution
+
+To resolve this issue, choose one of the following approaches:
+
+### Downgrade Telerik UI for Blazor
+
+Downgrade the `Telerik.UI.for.Blazor` package in your project to version `7.1.0` to ensure compatibility between the Blazor Native Viewer and the Telerik UI for Blazor components.
+
+### Switch to Blazor Report Viewer
+
+Use the [Blazor HTML5 Report Viewer]({%slug telerikreporting/using-reports-in-applications/display-reports-in-applications/web-application/blazor-report-viewer/overview%}) instead of the Blazor Native Viewer. The Blazor Report Viewer acts as a wrapper for the [HTML5 Report Viewer]({%slug telerikreporting/using-reports-in-applications/display-reports-in-applications/web-application/html5-report-viewer/overview%}) and does not depend on Telerik UI for Blazor components.
+
+### Wait for Updated Dependencies
+
+The Reporting team plans to update the `Telerik.UI.for.Blazor` dependency in the Q3 2025 release. Monitor the release notes for updates addressing this issue.
