Dim settings As new CefSharp.Settings()

settings.AutoDetectProxySettings = True

CefSharp.CEF.Initialize(settings)

Dim wv As new CefSharp.WinForms.WebView()

wv.Address = "http://www.baidu.com"

wv.Parent = e.Form.baseform

Dim pnl As WinForm.Panel = e.Form.Controls("Panel1")

pnl.basecontrol.controls.add(wv)

错误提示：

编译错误：未定义类型“SefSharp.Settings”

编译错误：未定义类型“CefSharp.WinForms.WebView”

版主能不能帮忙看看，新的引用该怎么定义？
