Answer 1

We had the same problem. What we found was a reference to the wrong database schema in the edmx file:

<EntitySet Name="MyTable" EntityType="Self.MyTable" Schema="**wrongSchemaName**" store:Type="Tables" />

By deleting the schema name our issue was resolved.

<EntitySet Name="MyTable" EntityType="Self.MyTable" Schema="" store:Type="Tables" />

Answer 2

The problem why the Data Table was not found, as suggested by DevilSuichiro in the comment, was due to the wrong Schema used. By default, EF 6 use dbo as default schema while my schema is not dbo. To make the model having default schema, an overriding for OnModelCreating event is needed:

public class EmployeeContext : DbContext {
    public DbSet<Employee> Employees { get; set; }
    protected override void OnModelCreating(DbModelBuilder modelBuilder) {
        modelBuilder.HasDefaultSchema("myschema");
    }
}

Also, thanks to Ivan Stoev for his suggestion to check the SQL generated by the EF.
