    <p>I have a MyDbContext in a separated Data Accass Layer class library project. And I have an ASP.NET MVC 5 project with a default IdentityDbContext. The two context use the same database, and I want to use AspNetUsers table to foreign key for some my tables. So I would like to merge the two Context, and I want to use ASP.NET Identity too.</p> <p>How can I do this?</p> <p>Please advice,</p> <p>This is my Context after merge:</p> <pre><code>public class CrmContext : IdentityDbContext&lt;CrmContext.ApplicationUser&gt; //DbContext { public class ApplicationUser : IdentityUser { public Int16 Area { get; set; } public bool Holiday { get; set; } public bool CanBePublic { get; set; } public string FirstName { get; set; } public string LastName { get; set; } } public CrmContext() : base("DefaultConnection") { } public DbSet&lt;Case&gt; Case { get; set; } public DbSet&lt;CaseLog&gt; CaseLog { get; set; } public DbSet&lt;Comment&gt; Comment { get; set; } public DbSet&lt;Parameter&gt; Parameter { get; set; } public DbSet&lt;Sign&gt; Sign { get; set; } public DbSet&lt;Template&gt; Template { get; set; } public DbSet&lt;Read&gt; Read { get; set; } protected override void OnModelCreating(DbModelBuilder modelBuilder) { modelBuilder.Conventions.Remove&lt;PluralizingTableNameConvention&gt;(); } } </code></pre> <p>Here is my RepositoryBase class:</p> <pre><code> public class RepositoryBase&lt;TContext, TEntity&gt; : IRepositoryBaseAsync&lt;TEntity&gt;, IDisposable where TContext : IdentityDbContext&lt;CrmContext.ApplicationUser&gt; //DbContext where TEntity : class { private readonly TContext _context; private readonly IObjectSet&lt;TEntity&gt; _objectSet; protected TContext Context { get { return _context; } } public RepositoryBase(TContext context) { if (context != null) { _context = context; //Here it is the error: _objectSet = (_context as IObjectContextAdapter).ObjectContext.CreateObjectSet&lt;TEntity&gt;(); } else { throw new NullReferenceException("Context cannot be null"); } } } </code></pre> <p>An exception of type <code>'System.Data.Entity.ModelConfiguration.ModelValidationException'</code> occurred in EntityFramework.dll but was not handled in user code</p> <p><strong>Additional information</strong>: One or more validation errors were detected during model generation:</p> <p><strong>Update: I found the solution.</strong></p> <p>I had to remove this naming convention:</p> <pre><code>protected override void OnModelCreating(DbModelBuilder modelBuilder) { modelBuilder.Conventions.Remove&lt;PluralizingTableNameConvention&gt;(); } </code></pre> <p>And migrate the ef cf model to db, to rename my tables with the nameing conventions of asp.net identity. It is working now!</p>

    2. COI second this question. The new Identity RTM seems to make referencing to User complicated.

    3. CO'Merge' means I want just one Context in the DAL project not two independent contexts in two projects, but using the same database.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
