I am having issues with scaffolding and having the entity framework recognize that I need a local database created - it is assuming that a SQL database should be communicating with my code, and thus crashes.

Per the book, EF supports the creation of a local database, but I couldn't find why the DbContext Class on page 83 was not registering properly. Am I suppose to add that code because I can't find it? If I am suppose to add it, where do I add it? It's hard to explain because I don't fully understand when Entity Framework steps in and utilizes the hardcoded DbContext and MusicStoreDB.

How does the DbContext, scaffolding process, and StoreManagerController interact? Why doesn't my StoreManagerController recognize that I have a local DbContext (MusicStoreDB).

Hi eswitzer,

As the authors seem busy elsewhere, perhaps us newbies should try to help each other. I'm certainly no expert so I can only ask the obvious question. I did the Ch4 exercises without too many problems so it should work for you also.

First, you must rebuild the project after adding any DB code. I assume you created the storemanager controller per page 85. My dialog is slightly different from page 86-87 (I use VS2013.4) but easy to relate to the book picture. I found the most important thing is to correctly select the model and context in the dialog. Did you see your context class OK at this point?

The code on page 83 is just an example to explain the concept. You don't need to type it in anywhere yet. The scaffolding steps beginning on page 85 (Executing The Scaffolding Template) will have you scaffold a controller, and step 5 will have you create the DbContext through the scaffolding dialog.

The database creation part is explained on page 92 and following, under "Creating Databases With The Entity Framework".
