Entity Framework Core - implementing Lazy Loading and Navigation Properties in EF Core 6
I need some guidance on I'm trying to figure out I'm sure I'm missing something obvious here, but I'm currently working on a .NET 6 application using Entity Framework Core 6, and I'm working with a frustrating scenario with lazy loading on my navigation properties... I've configured my DbContext to use lazy loading by installing the `Microsoft.EntityFrameworkCore.Proxies` package and enabling it in `OnConfiguring` like this: ```csharp protected override void OnConfiguring(DbContextOptionsBuilder options) { options.UseLazyLoadingProxies(); options.UseSqlServer("YourConnectionString"); } ``` However, when I try to access the navigation properties of my entities, they are not being loaded automatically. For example, I have a `User` entity with a navigation property `Posts`: ```csharp public class User { public int Id { get; set; } public string Name { get; set; } public virtual ICollection<Post> Posts { get; set; } } ``` And I'm querying a user like this: ```csharp var user = await context.Users.FirstOrDefaultAsync(u => u.Id == userId); var posts = user.Posts; // This should trigger lazy loading ``` Instead of getting the `Posts`, I receive a `System.NullReferenceException` because `user.Posts` is null. I've tried to ensure that `Posts` is marked as virtual, and I've even checked that lazy loading is indeed enabled, but it still doesn't work. Additionally, I've tried explicitly loading the navigation property using `Include`, and that works fine: ```csharp var userWithPosts = await context.Users.Include(u => u.Posts).FirstOrDefaultAsync(u => u.Id == userId); ``` Yet I would prefer to utilize lazy loading without needing to explicitly include every time. Is there something I'm missing in my configuration? Any help would be greatly appreciated! My development environment is Linux. The project is a service built with C#. I'd love to hear your thoughts on this. This is my first time working with C# 3.11. What would be the recommended way to handle this?
