Cannot call EntityModel from c# code-file

Question

I created an EntityModel in Visual Studio 2010 to use with Linq. What I see in my Model Browser are:

>AcrrualEntityModel.edmx
>>SteeringWheelModel
>>>Entity Types
>>>>TblFTEReportNew
>>>>>Field1
>>>>>etc..

In my Default.aspx.cs file I should be able to call SteeringWheelModel. This object is generated with the Entity Data Model Wizard. I can see the tables and fields in the model. So, the connection to the database works.

However, in my Default.aspx.cs file I should be able to create a new instance of SteeringWheelModel, so I can use Linq to use tables and fields.

Intellisense does not pick it up. The compiler does not recognize SteeringWheelModel.

What am I missing here? Some "using", some reference?

Thanks in advance!

You need to import the namespace of EntityModel class by adding a using statement to your code behind. Ex:

using app.data.models

Alternatively you could make sure they are in the same namespace, but I do not recommend that. Also, if these files are in differenet projects make sure your UI project has a reference to the EntityModel project.

Edit: To try to show you what I mean.

Here is a section of one of my projects. Each folder here has a different namespace.

data.abstract
data.concrete
data.entities

If I want to reference a class in another UI project i first need to add a reference to the data assembly to the UI project and then inside the UI project I need to import the namespace ex:

using data.abstract;
using data.entities;
