Upgrade Project Wizard crashes

The Upgrade (Project) Wizard crashes on the screen where it askes whether to use a backup.

The "Show me more" link gives this:

The wizard encountered an error while trying to handle user event.

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.Blazor.VSX.Wizards.ViewModels.UpgradeProjectWizardOptionsViewModel.GetInitialSelectedDirectory()
   at Telerik.VSX.Wizards.UpgradeProjectWizardOptions`2.GetPropertyValue(String propertyName)
   at Telerik.VSX.WizardEngine.Controls.WizardControlBase.PopulateCollectedValues(IPropertyDataDictionary gatheredData)
   at Telerik.VSX.WizardFramework.Pages.DynamicPageController.GetData()
   at Telerik.WizardFramework.Wizard.GetCurrentPageData()
   at Telerik.WizardFramework.Wizard.OnMoveNext()
   at Telerik.WizardEngine.Helpers.EventHelper.CatchExceptionAndSendReport(Action action)

 

I cannot continue to the next page. I want to upgrade the existing 3.5 to 3.6

Hi Noel,

Thank you for the additional information.

I'll add that to the backlog item we already have so we explore different scenarios which may produce the same outcome. Please follow the extension page mentioned previously for updates on the release of this fix.

In case you have any other questions, please get back to us.

Regards,
Nikola

It's a .Net 6 Blazor project, using the new, minimal project style. So (almost) no files are referenced in the csproj file (the one file referenced is a "link" to another location, to a "stylecop.json"). No Pages folder is referenced there or on disk.

Hi Noel,

Thank you for the details you have provided.

I was able to reproduce the exact same error however this involves having the _Layout file described as an item in the project file(csproj) and not having it physically on the hard drive. Could you please confirm whether this is the scenario at your end or if it is something different?

In general, this is not a common scenario, nevertheless, I would log an item in our backlog to improve the behaviour with one of the future releases of the Visual Studio extensions. You may follow the respective release notes on the Telerik UI for Blazor extension page.

Upgrading a single (component) project (upgrading all gives the same error for the first project processed), I get an error screen (attached). Clicking that "Show me more" link gives the following stack trace:

 

An error occurred while running the wizard.

Error executing custom action Telerik.Blazor.VSX.Actions.MultiProjectUpdateMasterPageAction: System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\w\new\Horizon30\Horizon30.Core.Configuration\Pages\_Layout.cshtml'.

   at Telerik.VSX.Actions.MultiProjectActionBase`1.Execute(WizardContext wizardContext, IPropertyDataDictionary arguments)
   at Telerik.VSX.WizardEngine.ActionManager.ExecActions()

 

The wizard is correct, that file doesn't exist. But I would expect either a nice error message (if it is required) or silently ignoring that part of the upgrade (if it isn't).

Hi Noel,

The Upgrade Wizard updates the Telerik UI for Blazor references and the script/styles references located in the _Layout.cshtml file if needed. As such it should work even if there is no such page. In this case, only the Telerik UI for Blazor NuGet package will be updated. That said could you please provide a bit more details about the error you received for the missing page? A stack trace as the one for the backup location would be very helpful.

Visual Studio restarts after the upgrade because we update the package sources in the solution-based NuGet.config and the new config has to be loaded for the updated package to be successfully restored. 

If you have any other questions, please get back to us.

Regards,
Nikola

I (now) have version 2022.3.912.1

Running the upgrade wizard didn't report that NullReferenceException anymore. Instead it crashed on missing ~/Pages/_Layout.cshtml files in my *component* projects. Adding those seemed to help. An unexpected restart of Visual Studio did happen, is that expected?

 

However, building the solution gave a lot of errors (like "The type or namespace name 'Razor' does not exist in the namespace 'Microsoft.AspNetCore'"). In the end I removed these _Layout files and just edited the project files by hand to update the version of the Telerik package reference - as that was basically what the Upgrade Wizard seemed to do in my case

Hello Noel,

I am sorry to hear about the difficulties you faced using our products.

This exact issue was reported previously and we have released a fix for it with the 2022.3.912 version of the Progress Telerik UI for Blazor extension. Could you please launch the Extension Manager through Extensions > Manage Extensions and double-check that this is the version you are using? 

If this is true and you are still getting the error, could you please provide a bit more details regarding the project you are trying to convert for example:

 - Where it is located (a network/shared drive, system drive, where the OS is located)

 - Where you are launching the wizard from (Extensions > Telerik main menu or context menu when you right-click on a project)?

 - What type of project it is.

Thank you in advance and I am looking forward to your reply.

Regards,
Nikola
