I'm creating an ASP.NET MVC web application. I've installed the Entity Framework. I have done the following model:
public class EmploymentHistory
{
public Guid Id { get; set; }
public Guid UserId { get; set; }
public int DateFromMonth { get; set; }
public int DateFromYear { get; set; }
public int DateToMonth { get; set; }
public int DateToYear { get; set; }
public string CompanyName { get; set; }
public string Address { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
public string County { get; set; }
[DisplayName("I was unemployed during this time")]
public bool IsUnemployed { get; set; }
}
I have created the following DbContext class:
public class EmploymentDbContext : DbContext
{
public DbSet<EmploymentHistory> EmploymentsHistory { get; set; }
}
And the connection string in my Web.config file looks like that:
<connectionStrings>
<add name="EmploymentDbContext" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=EmploymentsHistory;Integrated Security=False" providerName="System.Data.SqlClient"/>
</connectionStrings>
When I run the project, I can see the database EmploymentsHistory
in the Server Explorer in Visual Studio but when I expand it and then expand its Tables, I can't see the EmploymentHistory
table which I'm supposed to see.
Try adding a constructor to your EmploymentDbContext
class, so it would be like this:
public class EmploymentDbContext : DbContext
{
// constructor, which will also call DbContext's (base) constructor
public EmploymentDbContext() : base("name=EmploymentDbContext") { }
public DbSet<EmploymentHistory> EmploymentsHistory { get; set; }
}
By calling DbContext
's constructor, you're specifying the name of the connection string you'd like this subclass of DbContext
to attach to.
Edit:
Since you don't seem to be trying to use this connection anywhere currently, try explicitly adding a code-first migration. If you haven't already, run enable-migrations
in your Package Manager Console. Close out of the Configuration screen it presents, and then run add-migration EmploymentHistory
. Wait until it's finished, then run update-database
and see if that fixes it.
