Bug:Interop type 'mshtml.HTMLDocumentClass' cannot be embedded. Use the applicable interface instead.

在vs2010中运行HTMLDocumentClass doc =new HTMLDocumentClass(); 会出现Interop type 'mshtml.HTMLDocumentClass' cannot be embedded. Use the applicable interface instead.的编译错误。原因是我们添加 Microsoft.mshtml的时候，由于mshtml.dll太大，微软设置了这个属性Embed Interop Type =true .

解决的办法是：直接去掉Class后缀。

下面代码演示阻止WPF中WebBrowser 弹出javascript 出错对话框

    private void InjectDisableScript()
        { 

           string DisableScriptError =
           @"function noError() {
           return true;
            } 
           window.onerror = noError;";

            HTMLDocument doc = browser.Document as HTMLDocument;
          
       

            IHTMLScriptElement scriptErrorSuppressed = (IHTMLScriptElement)doc.createElement("SCRIPT");

            scriptErrorSuppressed.type = "text/javascript";

            scriptErrorSuppressed.text = DisableScriptError;

            IHTMLElementCollection nodes = doc.getElementsByTagName("head"); 

            foreach (IHTMLElement elem in nodes)
            {
                HTMLHeadElement head = (HTMLHeadElement)elem;
                head.appendChild((IHTMLDOMNode)scriptErrorSuppressed);

            }

        }
