Hi,
I am getting the following error message when trying to upgrade from 3.6.1 to 3.7.0. I tried multiple times without success.
===========================================================
An error occurred while running the wizard.
Error executing custom action Telerik.Blazor.VSX.Actions.MultiProjectUpdateMasterPageAction: System.InvalidOperationException: Sequence contains no matching element
at System.Linq.Enumerable.First[TSource](IEnumerable`1 source, Func`2 predicate)
at Telerik.Blazor.VSX.Actions.AdvancedUpdateMasterPageAction.RetrieveMasterPageSettingsUpgradeInfo(IPropertyDataDictionary arguments, IProjectWrap project)
at Telerik.Blazor.VSX.Actions.UpdateMasterPageAction.Execute(WizardContext wizardContext, IPropertyDataDictionary arguments, IProjectWrap projectWrap)
at Telerik.VSX.Actions.MultiProjectActionBase`1.Execute(WizardContext wizardContext, IPropertyDataDictionary arguments)
at Telerik.VSX.WizardEngine.ActionManager.ExecActions()
===========================================================
Thank you
