The web.config file for this project is missing the required DirectRequestModule.              

 

将应用程序集的模式由集成改为经典即可.

 

或者如下操作

 

 <system.webServer>

      <validation validateIntegratedModeConfiguration="false"/>

      <modules>

        <remove name="ScriptModule"/>

        <add name="DirectRequestModule" type="Ext.Net.DirectRequestModule, Ext.Net" />

      </modules>

  

    </system.webServer>
