Razor engine runtime error - Assembly not found

Question

I have added an assembly Eco.Interfaces.dll V6.0.0.0 to my website but I am getting a compile error at runtime telling me that I need to reference Eco.Interfaces 6.0.0.0

The line which causes the error is the first ActionLink

Line 36:                 <dl class="SystemMenu">
Line 37:                     <dt>Admin</dt>
Line 38:                     <dd>@Html.ActionLink("Client configuration", "Details", "Configuration")</dd>
Line 39:                     <dd>@Html.ActionLink("Offices", "Index", "Office")</dd>
Line 40:                 </dl>

System.Web.Mvc V4 - System.Web.Razor V2

Answer 1

Try setting Copy Local to true for the library using the Properties dialog in Visual Studio.
