Chapter 16: Try it out, page 607: Server Error in '/' Application

Hi,

I’m studying your ASP.NET book and got stuck in the try it out on page 607.
I installed the package successfully with the command you provided:
Install-Package Microsoft.AspNet.Providers
Everything in the try it out works fine until point 13. When I try to create a new account in the SignUp.aspx page, I get the following error:

Code:

Server Error in '/' Application.

In the bin folder I don't see the EntityFramework.dll file
But the package manager does inform me that everything is installed

Code:

PM> Install-Package Microsoft.AspNet.Providers
Attempting to resolve dependency 'Microsoft.AspNet.Providers.Core (≥ 2.0.0)'.
Attempting to resolve dependency 'EntityFramework (≥ 6.0.0)'.

I solved this problem with this command in the package console:

Install-Package EntityFramework

Ah, yes, that makes sense as that's a prerequisite for the providers. Earlier chapters that deal with data access work with EF as well so I am a bit suprised you didn't run into this earlier.

Cheers,
