是的，您需要从Microsoft下载更新的版本。然后使用新版本号和publickeytoken更新web.config。一种简单的方法是删除现有引用并添加对新dll的引用。然后还搜索你的项目，看看它是否在其他地方被引用，并确保在那里更新版本和publickeytoken。

Yes, you need to download the newer version from Microsoft. Then update your web.config with the new Version number and publickeytoken. An easy way to do that is remove the existing reference and add in the reference to the new dll. Then also search your project to see if it is referenced anywhere else and make sure to update the version and publickeytoken there as well.
