Incorrect .Net framework version is being displayed on server error page. RRS feed

  • Question

  • I have IIS 8.5 and .Net Framework version 4.7.2 installed in my machine. 
    My web application target framework is set to 4.7.2 in Visual Studio.  
    However, I have notice that when I get an application run time exception, the version information displayed at the bottom of the yellow server page says .Net Framework Version: 4.0.30319; Please may I know why it is not showing ver4.7.2.

  • Hi Rav Bob,

    Thank you for posting here.

    For the .NET Framework versions 4, 4.5, 4.5.1, and 4.5.2, the string representation of the returned Version object has the form 4.0.30319.xxxxx, where xxxxx is less than 42000. For the .NET Framework 4.6 and later versions, it has the form 4.0.30319.42000.

    For more details, please refer to the link below.
