Hi Bob,

Thanks for contacting Syncfusion support.

As per your error screenshot we suspect that the issue occurred since the scaffolding extension may installed with the older version or may not update properly to the latest version. Could you please follow the below steps to resolve the issue from your side.

1. In Visual Studio, go to Extensions -> Manage Extensions -> Installed -> Syncfusion Blazor Template Studio and click on the Uninstall button. 
2. Close the Visual Studio to start the uninstallation process
3. Then, open the Visual Studio again and check whether the Syncfusion scaffolding and Conversion and Migration extensions are available or not in the Extension Manager. 
4. If still Syncfusion Scaffolding and Conversion and Migration extensions are available in the Extension Manager, please click on the Uninstall button to uninstall them.
5. Then Close the Visual Studio to completing the uninstallation process. 
6. Now, download the latest Syncfusion Blazor Template Studio extension from the below marketplace link.
   https://marketplace.visualstudio.com/items?itemName=SyncfusionInc.Blazor-Extension
   
7. Then, double click on the downloaded Syncfusion Blazor Template Studio.vsix file and install it.
8. Now, check the scaffolding process.

Regards,
