Found markup element with unexpected name 'TelerikTreeList'

[Anju]

TRy to use the TelerikTreeList in one blazor application and it is showing as Found markup element with unexpected name 'TelerikTreeList'. Why it is not supporting. Am I missing some libraries?

Hello Anju,

I could suggest you follow the upgrade procedure again. The first time something might have gone wrong and some packages may be missing. The error you are getting indicates that the upgrade to our 2.16.0 was not successful.
