Feature Request - How to release resources from the ViewModel

[songminkyu]

Hi. Everyone
We are implementing the web browser and PDF preview function using the CefSharp MVVM method. However, after loading the PDF, I want to release resources depending on whether they are needed, but I want to know what the "ViewModel" handles.
As a temporary alternative, there is currently no method, so it is being used by calling dispose in the code behind it. Any help would be appreciated. :)
