C# - guide with Entity Framework Core and Lazy Loading optimization guide for Navigation Properties
I've been struggling with this for a few days now and could really use some help... 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. Despite configuring my entities correctly, accessing a navigation property results in an empty collection. Here’s a simplified version of my entity classes: ```csharp public class Blog { public int BlogId { get; set; } public string Name { get; set; } public virtual ICollection<Post> Posts { get; set; } } public class Post { public int PostId { get; set; } public string Title { get; set; } public int BlogId { get; set; } public virtual Blog Blog { get; set; } } ``` In my `DbContext`, I have: ```csharp public class BloggingContext : DbContext { public DbSet<Blog> Blogs { get; set; } public DbSet<Post> Posts { get; set; } protected override void OnModelCreating(ModelBuilder modelBuilder) { modelBuilder.Entity<Blog>().ToTable("Blogs"); modelBuilder.Entity<Post>().ToTable("Posts"); } } ``` I have also installed the necessary package for lazy loading with the following command: ``` Install-Package Microsoft.EntityFrameworkCore.Proxies ``` In my `Startup.cs`, I’ve configured the DbContext like this: ```csharp services.AddDbContext<BloggingContext>(options => options.UseLazyLoadingProxies().UseSqlServer(Configuration.GetConnectionString("BloggingDatabase"))); ``` When I try to load a blog and access its posts: ```csharp using (var context = new BloggingContext()) { var blog = context.Blogs.FirstOrDefault(b => b.BlogId == 1); var posts = blog.Posts; // This is empty! } ``` I also verified that there are posts related to the blog in the database, so I am puzzled as to why the lazy loading isn't occurring. I've tried enabling lazy loading by overriding the `OnConfiguring` method and ensuring the virtual keywords are correctly applied, but nothing seems to work. Any suggestions on what might be going wrong or additional settings I might be missing? I'm working on a web app that needs to handle this. Am I missing something obvious?
