Question

当我运行应用程序时，我收到如下错误：

Microsoft JScript运行时错误：Sys.ArgumentTypeException：类型为“Sys._Application”的对象无法转换为“Sys._Application”类型。参数名称：instance

Answer 1

将ScriptManager的 ScriptMode 属性设置为发布。

Answer 2

如果 web.config 未正确配置为使用Microsoft的ASP.NET Ajax，则会发生此错误。

如果您有VS2008，则会自动添加此设置。在VS2005中，如果您的ASP.NET项目不是以Ajax开头，则需要手动添加设置。

以下是一个例子：
