[solved]The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery`1[<> f__AnonymousType2`2[System.String,System.String]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1'

When I was trying to run the application I had faced this problem. I resolved by selecting the complete object that result will consists of complete customer objects. But before I selected a subset of the customer objects, just two members.

Problem:

var customerOrders = from customer in db.Customers 
                     where customer.ContactName.StartsWith("C")
                     orderby customer.ContactName                      
                     select new {customer.ContactName, customer.Phone }; 

I got the following error, 

The model item passed into the dictionary is of type'System.Data.Entity.Infrastructure.DbQuery`1[<>
f__AnonymousType2`2[System.String,System.String]]',but this dictionary requires a model item of type 
'System.Collections.Generic.IEnumerable`1[LinQTutoris.Models.Customer]'.

Solution:

edited the code,selecting the complete object of customer

var customerOrders = from customer in db.Customers                      
                     where customer.ContactName.StartsWith("C") orderby customer.ContactName    
                        select customer;
