Chapter 14 PlanetWrox.edmx
I have been working through the beginners book and have come across a problem that I can't get past.
I am using VS2013 for this entire project.
Within the "Try it Out" on pages 501 and 502 I don't get the ability to change the Code generation strategy property from None to default in step 7. The property is disabled and set to "T4".
Subsequently if I delete the *.tt files as pointed out in step 8, I can't reference PlanetWroxModel at all in step 10 with the Imports statement.
Regards
Kim

Hi Kim,
You may want to take a look here where Alan asked the same question: Ch 14 generating entity model
Cheers,
Imar

Hi Imar,
Thanks again for the quick reply.
I selected the entity framework version 6.0, unlike Alan. However I don't have the option to select other than "T4" in the code generation strategy property. This property is disabled.
How can I select entity framework 5.0, since I selected the "Don't show option" in step 4.
Regards
Kim

Hi Kim,
>>How can I select entity framework 5.0, since I selected the "Don't show option" in step 4.
Not sure which option you're referring to. When I add an EDMX, I can choose between 5 and 6, but I see no checkbox to never ask the version again. Or do you mean the option about suppressing the security warning?
I think if you uninstall the EntityFramework (using the Package Manager Console with the command Uninstall-Packge EntityFramework) you should be able to add an EDMX again and pick version 5.
Hope this helps,
Imar

Thanks Imar,
Just some additional notes, in version 2013 of VS for EDMX, the PlanteWroxEntities namespace must be different from the Entity Container name (Used PlanetWroxModel), and the Code Generation strategy has to be set to 'Legacy ObjectContext'.
Thus the imports for VB code is set to 'PlanetWroxModel' now all works fine.
Guess it must be difficult to continue to update your book for each version of VS if it changes each year.
Thanks Again

The hardest part is supporting people that use non-matching versions of the book and VS, as sometimes it's hard to see what they do.
I just finished an update of my book for VS 2013 and ASP.NET 4.5.1. where all this gets addressed "the proper" way. No legacy context, targeting EF 6 and using Model Binding instead of the more or less obsolete Entity Data Source control.

Hi Kim,
Amazon says March 24, which is probably accurate: http://www.amazon.com/Beginning-ASP-...rds=spaanjaars
