Question

I tried to upload my web site to a server. It was working fine with my local host, so I uploaded everything in my localhost wwwroot folder to the server and changed the connection string.

But there is this error:

Exception information: 
    Exception type: InvalidOperationException 
    Exception message: The pre-application start initialization method Start on type RouteDebug.PreApplicationStart threw an exception with the following error message: Could not load file or assembly 'Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

The project was nopcommerce.

What should be done to resolve this error?

You will need to include the dll with your project and add a reference to it as well.
