錯誤描述：

The 'targetFramework' attribute in the <compilation> element of the Web.config file is used only to target version 4.0 and later of the .NET Framework (for example, '<compilation targetFramework="4.0">'). The 'targetFramework' attribute currently references a version that is later than the installed version of the .NET Framework. Specify a valid target version of the .NET Framework, or install the required version of the .NET Framework.

解決方法：

將webconfig中的targetFramework的運行環境的配置刪除掉，重新運行就能看到問題點。然后再去解決
