推荐答案

参考 - 如何：将ASP.NET Web应用程序升级到ASP.NET 4 [ ^ ]。

Refer - How to: Upgrade an ASP.NET Web Application to ASP.NET 4[^].

Quote：

建议您使用Visual Studio执行升级所需的任务。如果不使用Visual Studio自动执行升级，则必须手动编辑Web.config文件，并且必须手动将IIS中的应用程序与.NET Framework版本4关联。

It is recommended that you use Visual Studio to perform the tasks that are required in order to upgrade. If you do not use Visual Studio to perform the upgrade automatically, you must manually edit the Web.config file and must manually associate the application in IIS with the .NET Framework version 4.

您需要检查具有正确.net框架的Web应用程序的应用程序池。

转到IIS并单击应用程序池。你能看到从ASP.NET 4.0开始的应用程序池吗？如果它存在，您已成功在IIS上注册.net 4.0。

如果您没有4.0应用程序池，请在答案中尝试以下步骤

You need to check the app pool of your web application having correct .net framework or not.
Go to IIS and click on Application Pools. Can you see application pool starting with ASP.NET 4.0? if it is there, you have successfully registered .net 4.0 on IIS.
if you don't have 4.0 app pool try below steps in the answer
