[Ch.14 Pg.503] Entity Framework model

Bassios · June 16th, 2016, 10:22 AM

Hi,

I'm having a bit of trouble completing the Try It Out that starts on Pg. 501 as when I get to step 10, I get the error message that the book warns me about (PlanetWroxEntities being out of scope), but I can't seem to fix it as even when I hand type Using PlanetWroxModel; nothing seems to work.

VS doesn't detect give the option of selecting "Using PlanetWroxModel;" or "PlanetWroxModel.PlanetWroxEntities" as shown in the Fig 14-3, I just get the bottom two options, "Generate class [...]" and "Generate new type..."

Any idea on how I can fix this?

Hi Bassios,

Take a look at this thread that deals with the same topic: the book and problem with EF

Cheers,

Hi Imar,

Thanks for your reply, unfortunately it doesn't help me as I have no idea what I need to search for on google to get the answer. If you could point me in the right direction, I'm happy to do the reading myself, I just don't know what the difference is between the book and how EF6 generates code.

Thanks

This might be a good start: https://www.google.com/?gws_rd=ssl#q...database+first

Many tutorials focus on MVC but you can use the web forms principles from my book to use it on Web Forms.

I would recommend sticking to EF5 to follow along with the book. Then when you get the hang of it you can switch to EF6 for your own projects.

Cheers,
