I copied a project to another computer and I have this error.

Could not load file or assembly 'System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Screenshot of error is in this part.

It means you are missing a reference in your project. Try to add the assembly it is referring to.

Solution 3

That assambly is part of MVC4. So either install MVC4[^], or this one: http://nuget.org/packages/CodeSharp.Package.AspNetWebPage/[^].

Solution 1

I cannot find that System.Web.Helpers.dll on my machine - it is likely not part of the .Net Framework 4. When you deploy your application on a different computer, you have to deploy that dll also (check its license, in case it is not your own product!).
