How to remove async if not needed, but required?

Question

C++ / C#

Tipo I do not need asynchronous execution, but then I can not get html.
.Result causes a deadlock.
Because of async in general, everything becomes bad in other threads. There is no async method for getting html. What's the catch?

The code:

private async void GetHTMLFromWebBrowser()
        {
            html = await browser.GetSourceAsync(); // как без await жить?
        }

Answer 1

Async.getAwaiter().getResult();
Where async is any asynchronous method
