here controller code.

namespace mvcapplication3.controllers {     public class customercontroller : controller     {         //         // get: /customer/          public actionresult index()         {             models.northwinddatacontext nwd = new models.northwinddatacontext();             return view(nwd.customers.tolist());         }      } } 

here view

<%@ page title="" language="c#" masterpagefile="~/views/shared/site.master" inherits="system.web.mvc.viewpage<mvcapplication3.models.customer>" %>  <asp:content id="content1" contentplaceholderid="titlecontent" runat="server">     index </asp:content>  <asp:content id="content2" contentplaceholderid="maincontent" runat="server">  <h2>index</h2>  </asp:content>  <asp:content id="content3" contentplaceholderid="featuredcontent" runat="server"> </asp:content>  <asp:content id="content4" contentplaceholderid="scriptssection" runat="server"> </asp:content> 

can give me hint fix it?

you're trying pass collection view that's designed single object.

change view declaration to

inherits="system.web.mvc.viewpage<ienumerable<mvcapplication3.models.customer>>
