Telerick for WinForms VS2008 - new project/covert fails

[Craig]

Any help or insights appreciated. This is for the WinForms library for VS2008.

When I try to create a new Telerick project, or convert an existing project, it fails. I'll paste in the error log below. 

Yes I know VS2008 is old and I should be using a newer version, but 2008 has features I really like, esp the MDI editor. 

What I've tried (suggested from Progress support folks) :

- Uninstalled, reinstalled

- Uninstalled, manually uninstalled the DLLs from the GAC, reinstalled, rebooted

Thanks for any assistance

Hi Craig,

We are sorry to hear that the extensions crash on your side.

Please, have in mind that although we continue to distribute the extensions for Visual Studio 2008, they have been deprecated for a few years now and no future development is planned. However, we will try our best to resolve the problem on your side.

So, let us know the following:

• What version(s) of UI for WinForms have you installed on you machine?
• Is this error available only for version 2018.2.621?
• What is the exact version of your Visual Studio? It will be very convenient if you could send us the whole formation from  the About Microsoft Visual Studio dialog (Help > About Microsoft Visual Studio).
• What is the version of your operating system?

Because the functionality of the extensions relies on various APIs, sometimes issues with the setup of .NET Framework and Visual Studio cause errors. In these cases repairing .NET Framework and Visual Studio may resolve these errors:

• Microsoft .NET Framework Repair Tool is the official tool provided by Microsoft.
• You can use the installation setup program to repair your Visual Studio 2008 instance.

Craig, note that if you have a successful installation of UI for WinForms, you can develop your applications based on a standard Windows Forms App (.NET Framework) template. All the controls and themes are available in the toolbox which is the most convenient way to use UI for WinForms. Here are some resources that you may find useful:

• Using default themes.
• Theme for Telerik Controls for WinForms.
• Telerik UI for WinForms documentation.

If you need to use our predefined templates, please let us know.

Regards,
Vesko
