Telerik UI for WPF Visual Studio Extension crash on upgrade wizard

[Damien]

Trying to upgrade my C# WPF application to the latest telerik version using the Upgrade Wizard,

It crash right after starting the upgrade with:

 

An error occurred while running the wizard.

Error executing custom action Telerik.Windows.WPF.VSX.Actions.MultiProjectUpdateReferencesAction: System.Runtime.InteropServices.COMException (0x80004005): This reference cannot be removed from the project because it is always referenced by the compiler.
   at VSLangProj.Reference.Remove()
   at Telerik.VSX.ProjectConfigurators.ApplicationReferenceManager.RemoveReferences()
   at Telerik.VSX.ProjectConfigurators.ApplicationReferenceManager.UpdateReferences()
   at Telerik.VSX.Actions.UpdateReferencesAction.UpdateReferences(IProjectWrapUIComponents projectWrap)
   at Telerik.VSX.Actions.MultiProjectActionBase`1.Execute(WizardContext wizardContext, IPropertyDataDictionary arguments)
   at Telerik.VSX.Actions.MultiProjectUpdateReferencesActionBase`1.Execute(WizardContext wizardContext, IPropertyDataDictionary arguments)
   at Telerik.VSX.WizardEngine.ActionManager.ExecActions()

 

Tried in VS2019 and VS2022, same results. Installed the latest Telerik extension from the VS Extension market.

Hi Damien,

This message usually appears when the Upgrade Wizard is used to update references that are added through a NuGet package. Usually, the wizard removes the old references and then replaces them with the newer version ones. If the references are added through a NuGet package the wizard cannot remove the old reference and throws this exception. 

In this case, I would suggest opening the solution and then using the NuGet Package Manager available through Tools > NuGet Package Manager > Manage NuGet Packages for Solution... to update the packages' version which will also update the references.

Please let us know if this worked out for you.
