Hi, I am a beginner in Revit API and I am not good at English. I ask for your understand.

We made a Revit addIn program with Telerik, and it works perfact in Revit api 2019.

We tried to made smae project in Revit api 2018, but it throw exception(telerik System.Windows.Markup.XamlParseException'(PresentationFramework.dll), Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an exception).

I think it's related to Telerik, but I cant know What is wrong.

Please Help me , Thank you.

Hi @baekdi,

Kindly provide a sample code that throws the exception.

Also note that Revit officially doesn't support Revit 2018.

But there is an experienced team of experts who will assist in debugging the sample code and assist if the issue is with Revit.

From a quick search, it looks like that exception means WPF failed to find some resource referenced in your (or telerik's) XAML. In your 2018 project, make sure you have all the same resources and references that your 2019 project has.
