I am building a domain model that requires several tables to be able to be references by more than one possible parent table. Something like you might have a table to store notes or files and those notes and/or files can be associated with different parent entities. Not that the same "file" or "note" can be associate with multiple owners, but that of 10 rows in a "files" table, 3 of them might be owned by rows from a "Customer" table, 3 of them might be owned by rows from an "Orders" table, and 4 of them might be owned by rows from a "Person" table. The owning tables all have virtual

I'm using EF5 code first to generate my database schema, but my new navigation property is being named in an undesirable way in the table. here is the model I'm working with. public class User { [Key] public long UserId { get; set; } ... **public virtual ICollection<ImagePermission> KeepThisNavigationName { get; set; }** } However, After I've updated my database and examine the table columns, the column is named: dbo.ImagePermission.User_UserId And I would like it to be named dbo.ImagePermission.KeepThisNavigationName_UserId I believe there is a way to do this using the Fluent API, but after

I have created a Class Library project with the following .csproj: <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFramework>netcoreapp1.1</TargetFramework> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="1.1.1" /> <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.1" /> <PackageReference Include="Microsoft.EntityFrameworkCore.sqlserver.Design" Version="1.1.1" /> <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="1.1.0" /> </ItemGroup> </Project> When running the command: Add

In Code First approach, how to define my entity so that: CreatedOn NOT NULL - value is generated on insert by the db with the current timestamp Updated NULL - value is generated on update by the db with the current timestamp Sample Entity: public class MyEntity { public int Id { get; set; } public string Name { get; set; } [DatabaseGenerated(DatabaseGeneratedOption.Identity)] [Column(TypeName = "TIMESTAMP")] public DateTime CreatedOn { get; set; } [Column(TypeName = "TIMESTAMP")] public DateTime UpdatedOn { get; set; } } DbContext: public class MyContext : DbContext { public MyContext

I know how to do seed data with the migrations API in EF 4.3. I've been playing with that all night. However, my ultimate goal is to get my project to the point where a user can pull it from source control and press F5 and they are good to go, database, seed data, and all. Currently code-first does an excellent job of building the DB on a fresh build but seed data isn't inserted until I do Update-Database in the package manager console. At that point it runs the seed method and inserts my seed data. Is it okay to just do that in the OnModelCreating method? Can I still take advantage of the

I have a Holiday table and a User table. The Holiday table has columns RequesterID and AuthorisedByID , which both link to the primary key of the User table. This is my Holiday model: public class Holiday { [Key] [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public Guid HolidayId { get; set; } [ForeignKey("UserId")] public virtual User User { get; set; } public Guid RequesterId { get; set; } public Guid? AuthorisedById { get; set; } } I am unable to declare the AuthorisedByID as a foreign key in the User table just like I think I did with RequesterId column. I wonder if you can give me
