Working with SQL views in Entity Framework Core

Question

For example, I have such model:

public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }

    public BlogImage BlogImage {

The EF Core doesn't create DBset for the SQL views automatically in the context calss, we can add them manually as below.

public partial class LocalDBContext : DbContext
{ 

    public LocalDBContext(DbContextOptions options) : base(options)
    {

    }

    public virtual DbSet YourView { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity(entity => {
            entity.HasKey(e => e.ID);
            entity.ToTable("YourView");
            entity.Property(e => e.Name).HasMaxLength(50);
        });
    }

}

The sample view is defined as below with few properties

using System;
using System.Collections.Generic;

namespace Project.Entities
{
    public partial class YourView
    {
        public string Name { get; set; }
        public int ID { get; set; }
    }
}

After adding a class for the view and DB set in the context class, you are good to use the view object through your context object in the controller.
