我需要一些关于Microsoft Visual Web Developer 2010 Express的错误信息的帮助。
我想为我的网站创建一个画廊，所以我从codeplex下载了NotesForGallery。我按照安装说明将参考添加到了项目中。然后说明说：
在Web.Config文件（httpHandlers部分）中注册ThumbnailHandler：
<httpHandlers>
…
<add verb="*" path="ThumbnailHandler.ashx" type="NotesFor.ThumbnailHandler, NotesForGallery"/>
…
</httpHandlers>
所以我在解决方案中打开web.config文件并将其添加进去。当我尝试启动网站（点击Web Developer中的播放按钮）时，会出现错误信息：
未识别的配置部分httpHandlers。
我得到的完整错误列表如下：

我创建的项目是网站，如果有帮助的话。
完整的web.config如下：
<configuration>
<connectionStrings>
<add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
</connectionStrings>

如果您能帮助我，将会很有帮助，因为我不确定自己做错了什么。
