implementing Lazy Loading in Entity Framework Core – Missing Navigation Property Values
I'm working on a personal project and I'm working with a question with lazy loading in Entity Framework Core 6.0 where my navigation properties are not being populated as expected. I have a simple model with `Blog` and `Post` entities where each `Blog` can have multiple `Posts` associated with it. I've enabled lazy loading by installing the `Microsoft.EntityFrameworkCore.Proxies` package and configuring it in my `DbContext`. Here’s the relevant part of my context: ```csharp public class BloggingContext : DbContext { public BloggingContext(DbContextOptions<BloggingContext> options) : base(options) { } public DbSet<Blog> Blogs { get; set; } public DbSet<Post> Posts { get; set; } protected override void OnModelCreating(ModelBuilder modelBuilder) { modelBuilder.Entity<Blog>() .HasMany(b => b.Posts) .WithOne(p => p.Blog); } } ``` And here are my entity classes: ```csharp public class Blog { public int BlogId { get; set; } public string Url { get; set; } public virtual ICollection<Post> Posts { get; set; } } public class Post { public int PostId { get; set; } public string Title { get; set; } public string Content { get; set; } public int BlogId { get; set; } public virtual Blog Blog { get; set; } } ``` However, when I retrieve a `Blog` object like this: ```csharp using (var context = new BloggingContext(options)) { var blog = context.Blogs.FirstOrDefault(b => b.BlogId == 1); Console.WriteLine(blog?.Posts.Count); } ``` I get `0` for the count of posts instead of the actual number of posts. I've confirmed that there are indeed posts linked to that blog ID in the database. I've also tried explicitly loading the navigation property using `context.Entry(blog).Collection(b => b.Posts).Load();`, and that works fine, but I really want to use lazy loading if possible. I've checked that the navigation properties are defined as virtual, and I have set everything up according to the documentation. Is there something trivial I'm missing that could cause the lazy loading to unexpected result? Any insights would be greatly appreciated! I'm working on a application that needs to handle this.
