Running on WSL linux using .net6 and Quick OPC 5.71

I created the demo as described in opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User's...%20Visual%20Studio%20Code.html

Get this error when calling
var client = new EasyUAClient();

This does not occur when running under windows.


"One or more errors occurred. (Access to the path '/usr/share/IsolatedStorage/4afkimrw.2cy/ut00wkwg.uzs' is denied.)"
