Following the procedure in text book Chapter 4 to create the StoreManagerController does not work.

Others on stackoverflow suggested a solution was to manually create the MusicStoreDB class and select it as the data context from the drop down list.
This solved my problem.

I am using Visual studio 2015.

Hello,

I have the same issue and find the same solution but it would be nice to have an official answer.

Have a nice day.
