Could not load file or assembly System.Web.Http.WebHost after published to Azure web site

Question

I created a web project and it runs well in Visual studio. However, I got the following error after published it to azurewebsites. What can cause the issue?

Answer 1

For me worked adding the following section to web.config file:

...
    
    ...
        
            
            
        
    ...

This example stands for MVC 5.1. Hope it will help someone to resolve such issue.
