How to access public method declared in App.xaml.cs?

[pbanosdev]

Given a ToolWindow I created with a webView2 component inside, there are some methods interacting with the webView instance in App.xaml.cs that I need to call from outter classes, for example a Command class.

Obviously doing App app = new(); from the Command class sets the WebView2 to null. Also tried to make App.xaml.cs singleton class but didnt work either.

Sorry if the question is too dumb but I find myself a bit lost in this topic.

As I mentioned, the solution was pretty much dumb.

Only thing I did was implement a Singleton initialization in App class;

private static App _instance;

(will implement synclocks for concurrency problems)
public static aXetChatControl Instance
{
get
{
return _instance;
}
}

//wherever your App ToolWindow is completely initialized
_instance = this;

Now access App.Instance from everywhere

Apologies for the thread, I'll mark it as solved.
