Answer 1

It looks like your IIS settings are not matching.

If you go to your IIS Manager and navigate to Application Pools and look for the published(your Project name) folder

Select your Published project from the list

Click on Basic Settings from Actions pane

Change the .NET Framework Version to v4.0xxxxx
