Unhandled exception after upgrade to latest version

[Toby]

I have just recently upgraded to the latest version of WinForms (2022.2.622.40), along with upgrading from .net 4.6 to 4.7.2 to take advantage of High DPI updates.

When I start my application, is simply goes away without reporting any error.

When I look at the Windows Event Viewer Application Logs I see the following error:

Framework Version: v4.0.30319

I'm running on Windows 11, and have merged all dll's together using ILmerge (if t

I should add that my form has a single RadPictureBox with a small image loaded from the project resource but has defaults for SvgImage. DefaultImage and DefaultSvgImage 

Any ideas? is there a workaround ?

Thanks in advance

Hello Toby,

I am sad to hear that you are experiencing problems with Telerik UI for WInForms. 

I suspect that either the update did not go well or that ILmerge might have something to do with your issue. I would suggest doing a clean install of the latest version - first, uninstall all previous versions that you have and then install the latest. After that, you can try if you are still receiving the error. If the problem is not solved, please feel free to send us your project that is reproducing the issue, so we can investigate it further.

I hope this information will help you on your way. If you have further questions do not hesitate to write back.

This woul dappear to be an issue with using ILmerge, no issues when using unpacked dll's. Do you know of any alternatives to ILmerge ?

Hi Toby,

You can check the following articles discussing the various approaches for application deployment and redistribution. Keep in mind, that our assemblies can be freely distributed with the exception of the Telerik.WinControls.UI.Design.dll.

• Redistributing Telerik UI for WinForms
• Application Deployment

If none of the suggested approaches in the articles works for you can check the following ways:

• LibZ
• Fody/Costura
• LinkerSmartAssembly
• ILRepack...
  

You can search for even more. Just keep in mind that we haven't tested any of them, so you will have to try the one that works best for you.
