code-first

Creating a web site using code first, for my own piece of mind i would like to be able to explore the db it creates like you can when you use database first and create the SQL server db within VS2010. I have had a look around, and the only related information i can find seems to be using a previously existing db with code first, I want the db to be made by code first and i just want to know where it is, or how to change the default location of it so i can look in it. I have had a fiddle with the connection strings in the config file, but don't really know what i am doing so havent had any

I just started using Code first approach for creating databases. I have following 3 tables : public partial class AccountHolder { public int AccountHolderId { get; set; } public virtual List<Address> Address { get; set; } } public partial class Nominee { public int NomineeId { get; set; } public virtual List<Address> Address { get; set; } } public partial class Address { public int AddressId { get; set; } public int AccountHolderId { get; set; } public AccountHolder AccountHolder { get; set; } public int NomineeId { get; set; } public Nominee Nominee { get; set; } } Here AccountHolder and

I'm trying to learn code first within the Entity Framework and am having trouble modelling a relationship. It's a basic HR database which for the sake of this has two entities, Employees and Departments. The Employee belongs to a department and the department has a Team Administrator and a Manager, both of whom are in effect employees. I've tried to model this using the following: EMPLOYEE public int? DepartmentID { get; set; } public virtual Department Department { get; set; } Context: modelBuilder.Entity<Employee>().HasOptional(x => x.Department); DEPARTMENT public class Department {

I am building an ASP.Net MVC4 web application with Entity Framework 5. I had to use an existing sql server database but also wanted to use Code First, so I followed this tutorial http://msdn.microsoft.com/en-us/data/jj200620.aspx My application uses automatic migrations with Entity Framework. The version of sql server I was using throughout the development phase was 2008, however, at the last minute I've been told the database needs to work on sql server 2005. I got the database I was using in sql server 2008 setup (exact tables, property names, relationships etc) on sql server 2005. However,

I have classes called Course, Student and Teacher like this public class Course { [Key, DatabaseGenerated(DatabaseGenerationOption.Identity)] public Guid CourseId { set; get; } public ICollection<Student> Students { set; get; } public Teacher Teacher { get; set; } } public class Student { [Key, DatabaseGenerated(DatabaseGenerationOption.Identity)] public Guid StudentId { set; get; } public ICollection<Course> Courses { set; get; } } public class Teacher { [Key, DatabaseGenerated(DatabaseGenerationOption.Identity)] public Guid TeacherId { get; set; } public ICollection<Course> Courses { get;

I am using EF4 CTP5 to try to persist a POCO object that is split among two tables, the link being the ContactID. When i save a contact, i want the core contact information saved in one table (Contacts), and the link to the user who owns the contact saved in another (UserToContacts). I have the custom mapping defined below, but when I SaveChanges, i get the following error: A value shared across entities or associations is generated in more than one location. Check that mapping does not split an EntityKey to multiple store-generated columns. Any ideas would be greatly appreciated! protected
