This resolves when the browser navigates to a new URL or reloads. It is useful for when you run code which will indirectly cause the browser to navigate. A common use case would be when executing javascript that results in a navigation. e.g. clicks a link This must be called before executing the action that navigates the browser. It may not resolve correctly if called after.

Make sure an object is bound in javascript. Executes against the main frame

Evaluate Javascript in the context of the MainFrame of the ChromiumWebBrowser. The script will be executed asynchronously and the method returns a Task encapsulating the response from the Javascript. The result of the script execution in javascript is Promise.resolve so even no promise values will be treated as a promise. Your javascript should return a value. The javascript will be wrapped in an Immediately Invoked Function Expression. When the promise either trigger then/catch this returned Task will be completed.

The script will be executed asynchronously and the method returns a Task encapsulating the response from the Javascript This simple helper extension will encapsulate params in single quotes (unless int, uint, etc).

Execute a method call over the DevTools protocol. This is a more structured version of SendDevToolsMessage. ExecuteDevToolsMethod(IBrowserHost, Int32, String, JsonString) can only be called on the CEF UI Thread, this method can be called on any thread. See the DevTools protocol documentation at https://chromedevtools.github.io/devtools-protocol/ for details of supported methods and the expected parameters dictionary contents. See the SendDevToolsMessage documentation for additional usage information.

Execute Javascript in the context of this Browsers Main Frame. As the method name implies, the script will be executed asynchronously, and the method therefore returns before the script has actually been executed.
