I have an old .net application that is no longer supported or being devolped. I need to make some changes and would also like to fancy up the interface. I used justdecompile to decompile it but I am getting a lot of XAML errors -
The property 'StyleManager.Theme' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'. Line 57 Position 116

.
The application uses

Telerik.Windows.Controls.Data.dll,Telerik.Windows.Controls.dll,Telerik.Windows.Controls.Docking.dll, Telerik.Windows.Controls.Input.dll, Telerik.Windows.Controls.Navigation.dll,Telerik.Windows.Data.dll

I ran the upgrade wizard on the project and it completed without any error I think it upgraded from Telerik version 2013. Can I upgrade this project to have no XAML and only use implictit styles?

Hello Jay,

Yes, you can upgrade the project to use Implicit Styles, you can check the following topic on how this approach works:
Setting a Theme (Using Implicit Styles)

However, please note that StyleManager is still available and it is strange that you're receiving this error. Please check whether all the references are the same version and are coming from the same location.

Hello Adeline,

The telerik namespace should be defined like this:
