ChromiumWebBrowser Constructor (HwndSource, String, Size)

Version 112.3.0
Initializes a new instance of the ChromiumWebBrowser class. Use this constructor to load the browser before it's attached to the Visual Tree. The underlying CefBrowser will be created with the specified size. CEF requires positive values for Width and Height, if values less than 1 are specified then the default value of 1 will be used instead. You can subscribe to the LoadingStateChanged event and attach the browser to its parent control when Loading is complete (IsLoading is false).
