Things to note when Upgrading from CefSharp 1

Switch CefSharp Version

• Remove CefSharp1 References (CefSharp, CefSharp.WinForms)
• Delete all libs / locales of CefSharp1
• Close Visual Studio completely and then reopen
• Install CefSharp3 through Nuget (I just installed CefSharp.WinForms - it installs all required libraries as well)
• Close Visual Studio completely and then reopen
• Specify platform (x86 / x64)

Change class names

• RenamedWebView toChromiumWebBrowser
• RenamedLoadCompleted toFrameLoadEnd
• RenamedCEF toCef
• RenamedCefSharp.Settings toCefSettings
• Change BrowserSettings initialization

webView=newWebView(url,browserSettings);tothis webView=newChromiumWebBrowser(url);webView.BrowserSettings=browserSettings;

• RenameExecuteScript toExecuteScriptAsync
• No morewebView.PropertyChanged (Use individual events inWinForms or DataBinding inWPF)
• ChangeRequestHandler:
  1. removeRequestHandle andDownloadHandler class implementations
  2. addDownloadHandler
  3. change

  webView.RequestHandler=newRequestHandler();towebView.DownloadHandler=newDownloadHandler();

• ILifeSpanHandler.OnBeforePopup has different parameters
  • so Implement Interface ofILifeSpanHandler and remove the old function signature
