AllowsTransparency and WebBrowser compatibility issue solutions

AllowsTransparency and System.Windows.Controls.WebBrowser compatibility issues, can read this article, so the reason is not much to say, the most fundamental is because the MS to Win32 bottom WebBrowser simple package into System.wind oWS. Controls.webbrowser

The solution is also very simple, but the online most of the articles are missing and the code is obsolete (various kinds of code errors, the error does not refer to the version and other reasons, but some simple punctuation; I don't believe he's a hand code, rather than a copy of the VS-written code into the article, this irresponsible person's article still need to see? ), so I sorted it into a class for easy invocation

Now all pay attention to the rapid development, if your article can not be a substantial help to others, even if not a good article, if your article not only did not help but waste other people's development time then there is no need to send the rubbish;

Because this article is relatively simple, so added a small amount of spit groove, in order to prevent the body discomfort nausea and vomiting, ignoring the above content, down the text to the positive turn
