When there is empty folder under "%appdata%\Telerik\Updates" the WinForms Upgrade wizard fails with

Telerik VS extensions may cause performance issues that impact both the responsiveness and the overall performance of Visual Studio.

VS 2022 17.5.1 successfully converts a blank WinForms project without any Telerik control in it.

VS 2022 17.6.2  hangs:

When you want to do the Upgrade Wizard, the following error appears: Failed to execute command. System.IO.DirectoryNotFoundException: Could not find a part of the path 'c: \ users \ quinteju \ appdata \ local \ microsoft \ visualstudio \ 16.0_c92db9cd \ extensions \ pfzn5mj3.wxk \ ProjectManagement \ Upgrade \ ScenarioDefinition.xml'. at System.IO .__ Error.WinIOError (Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init (String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHostPath) at System.IO.FileStream..ctor (String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize) at System.Xml.XmlDownloadManager.GetStream (Uri uri, ICredentials credentials, IWebProxy proxy, RequestCachePolicy cachePolicy) at System.Xml.XmlUrlResolver.GetEntity (Uri absoluteUri, String role, Type ofObjectToReturn) at System.Xml.XmlTextReaderImpl.OpenUrlDelegate (Object xmlResolver) at System.Threading.CompressedStack.runTryCode (Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup (TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.CompressedStack.Run (CompressedStack compressedStack, ContextCallback callback, Object state) at System.Xml.XmlTextReaderImpl.OpenUrl () at System.Xml.XmlTextReaderImpl.Read () at System.Xml.XmlLoader.Load (XmlDocument doc, XmlReader reader, Boolean preserveWhitespace) at System.Xml.XmlDocument.Load (XmlReader reader) at System.Xml.XmlDocument.Load (String filename) at Telerik.VSX.WizardEngine.Configuration.ScenarioDefinition.Deserialize (String fileName) at Telerik.VSX.ProjectConfiguration.ProjectConfigurationTypeSelectorBase.GetScenario (ProjectManagementScenarioPath path) at Telerik.WinControls.VSX.ProjectConfigurators.ProjectConfigurationTypeSelector.ProjectUpgrade (IPropertyDataDictionary additionalPreWizardData) at Telerik.WinControls.VSX.ProjectConfigurators.StreamlinedProjectConfiguration.StartUpgradeWizard () at Telerik.WinControls.VSPackage.CommandExecutor.Execute (UInt32 commandId) at Telerik.VSX.VSPackage.PackageBase.CommandCallback (Object sender, EventArgs e) 

 

I already reinstalled three times and it doesn't work in any way.  :(

 

Steps to reproduce:

1. Install R1 2021 SP1 (2021.1.204)
2. Create a Telerik WinForms project and drag a RadTostNotificationManager from the Toolbox and drop it onto the form. The following two references are required for using RadToastNotification:

   

   

   The important information here is the version of the Microsoft.Toolkit.Uwp.Notifications: 6.1.0.0

   

3. Run the Upgrade Wizard and upgrade to R2 2021 (2021.2.511):

After the upgrade process is successfully completed, you can see that the Toolbox version is successfully updated as well as the Telerik references in the project:

However, the version of the Microsoft.Toolkit.Uwp.Notifications still remains 6.1.0.0 even though in the installation folder we distribute the updated version 7.0.0.0:

Then, if you try to build the project, you will see the following error message:

Workaround: Remove the existing Microsoft.Toolkit.Uwp.Notifications assembly and add it anew using the references from the installation folder: C:\Program Files (x86)\Progress\Telerik UI for WinForms R2 2021\Bin40 It is expected to be the correct version 7.0.0.0.  

 

 

After update the Copy Local is set to False
