Merge IdentityDbContext and DbContext ASP.NET MVC

问题

I would like to only have one DbContext in my ASP.NET MVC project. How should I merge the default IdentityDbContext with my own code first DbContext? They are using the same database.

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext()
            : base("SignalRChat")
        {
        }
    }

This is the default one provided in the IdentityModel.cs class.

Is it safe to do the following? And append my own DbSets?

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("SignalRChat")
    {
    }

    public DbSet<Student> Students { get; set; }
    public DbSet<Standard> Standards { get; set; }
}

Any advice is much appreciated!

Yes, it is perfectly fine to add DbSet declarations in the DbContext classes. Normally you would maybe create a context for a related group of tables that makes sense when you access it from your repositories, e.g. ApplicationDbContext for user registration, login etc. another for Students and related entities.

If you have many contexts maybe you should check for the bounded context "pattern" https://channel9.msdn.com/Events/TechEd/NorthAmerica/2013/DEV-B336#fbid=wH4n-081m_U.
