Unexpected behavior with Entity Framework Core 7 and Lazy Loading in ASP.NET Core 7
I am experiencing an issue with Entity Framework Core 7 where lazy loading does not seem to be working as expected in my ASP.NET Core 7 application. I have set up my navigation properties with virtual keywords, but when I try to access those properties, they return null instead of the expected related entities. Here's a snippet of my model classes: ```csharp public class Author { public int Id { get; set; } public string Name { get; set; } public virtual ICollection<Book> Books { get; set; } } public class Book { public int Id { get; set; } public string Title { get; set; } public int AuthorId { get; set; } public virtual Author Author { get; set; } } ``` I also ensured that I have called `services.AddDbContext<MyDbContext>(options => options.UseSqlServer(connectionString));` in my `Startup.cs` and that `LazyLoadingEnabled` is set to true in my `DbContext`: ```csharp public class MyDbContext : DbContext { public MyDbContext(DbContextOptions<MyDbContext> options) : base(options) {} public DbSet<Author> Authors { get; set; } public DbSet<Book> Books { get; set; } protected override void OnModelCreating(ModelBuilder modelBuilder) { modelBuilder.Entity<Author>().Navigation(a => a.Books).UsePropertyAccessMode(PropertyAccessMode.Lazy); } } ``` Despite following these steps, when I retrieve an `Author` and attempt to access the `Books` property, it remains null. I have also double-checked that I am not using `AsNoTracking()` in my queries, which might prevent loading related entities lazily, but it’s not the case here. Here’s how I retrieve the data: ```csharp public async Task<Author> GetAuthorWithBooksAsync(int authorId) { return await _context.Authors.FindAsync(authorId); } ``` I have tried different approaches, such as eagerly loading the related data using `Include()`, and that works fine, but I need lazy loading for other scenarios. I am not sure if there are any additional settings I might be missing or if there’s a known issue with lazy loading in EF Core 7. Any insights would be appreciated!
