In Chapter 14, I loaded the database and the folders to my solution. After I compiled the project I ended up getting 174 errors. I believe this might have to do with Entity Framework. All of my errors are on the Designer.CS file, and they range from things like "The type or namespace name 'ObjectSet' could not be found. This is happening for 'EntityReference', 'EntityObject', 'EntityCollection', etc.

Is there any way that I can fix this?

Thanks!

Hi there,

Which version of Visual Studio are you using? VS 2010 as the book assumes?

If you're using a later version, do you see a few .tt files in your app_code folder on disk?

If I know the version you're using, I might be able to figure out what's going on.

Cheers,

Imar

Hey Imar, thanks for getting back to me.

I'm actually using Visual Studio 2012. From what I am reading 2010 and 2008 don't seem to have this same issue. I'm wondering if it is a file path thing.

For VS 2012, try this:

1. With the designer for the EDMX file open, Click somewhere on an empty spot of the designer surface and press F4 to open the Properties Grid. Change the Code Generation Strategy property from None to Default.

2.Save and close the diagram and then delete the fi les PlanetWrox.tt and PlanetWrox.Context.tt from the App_Code folder.

Rebuild the project (Webite | Rebuild or press Ctrl+Shift+B) and then try again.

Does it work then?

Imar

Hey Imar,

I tried changing the code generation strategy to default, I ended up just right clicking to hit "reset" and the field changed to "Legacy ObjectContext" I deleted the .tt file and rebuilt it but I am still getting 459 errors.

Does your project have a reference to the Entity Framework? (Check the web.config for the references).

Also, try running the following command from the Package Manager Console:

Install-Package EntityFramework

You may need to uninstall first, using

Uninstall-Package EntityFramework

Hope this helps. If not, can you make a zipped version of your site available somewhere so I can take a look?

Sorry for the extremely late reply.

This worked fine.
