"'Could not load file or assembly 'Elmah' or one of its dependencies. The system cannot find the file specified'' after using Elmah.MVC in NuGet

Question

I have a MVC app, I used http://nuget.org/ to install Elmah for MVC, I Was able to install it and run it successively.

After few week reopening Visual Studio I Get this error:

Could not load file or assembly 'Elmah' or one of its dependencies. The system cannot find the file specified. 


Error
<httpModules>
Line 73:       <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" />

I tried to add a reference in the project to Elmah.Mvc but with no success. Could you point me out how to fix this problem? Thanks

Answer 1

Reinstall Elmah.Mvc via NuGet would be my advice. If this doesn't help, try reinstalling the elmah.corelibrary NuGet package (being a dependency of Elmah.Mvc).
