PeterWe may get the following error after publishing a website on IIS.
Parser Error Message
"Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive."
To fix it, we need to follow the below troubleshooting steps.
- Check on which .NET version the application is developed. Let's assume, it's .NET 4.0.
- Open IIS Manager and find the Application Pool, on which your website is hosted.
- Go to that Application Pool and check the .NET version and change it to 4.0 accordingly by clicking on Basic\Advanced Settings.
If .NET 4.0 is not listed, go ahead and install it.
- If it still won't show up, go to command prompt and fire the below command to find a list of ASP.NET versions installed:
C:\Windows\Microsoft.NET\Framework\v4.0.30319>aspnet_regiis.exe -lv
In the output, if .NET 4.0 is not listed, register it by firing the below command:
C:\Windows\Microsoft.NET\Framework\v4.0.30319>aspnet_regiis.exe -I.
- It should show up as .NET 4.0 in the .NET Framework Version dropdown for the application pool.
