Question
I am using EF Core. I am using DbContext.Set() method but it is giving me the error - "Cannot create a DbSet for 'MediaDate' because this type is not included in the model for the context.'"
Below is my code:
var context = new GoldentaurusContext();
DbSet<MediaDate> set = context.Set<MediaDate>();
mediaDateList = set.FromSql("[dbo].[sp_GetMediaDate]")
.Select(x => new SelectListItem { Text = x.DateText, Value = x.DateValue })
.ToList();
The MediaDate class:
public class MediaDate
{
public string DateText { get; set; }
public string DateValue { get; set; }
}
Why it is requiring me to add the MediaDate class to the DbContext class?
Please help what I am doing wrong?

Your DB Context class should be like below.
public partial class DatabaseContext : DbContext
{
public DatabaseContext (string ConnectionString) : base(new DbContextOptionsBuilder().UseSqlServer(ConnectionString).Options)
{
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Query<MediaData>();
}
Add your models in the DatabaseContext using model builder. This is how I have resolved this isssue
