implementing Entity Framework Core and Lazy Loading in a .NET 6 Web API
I'm not sure how to approach I'm trying to implement I'm experiencing unexpected behavior with Entity Framework Core's lazy loading feature in my .NET 6 Web API project. I have a parent entity `Order` that has a navigation property to a collection of `OrderItems`. I expect to retrieve the related `OrderItems` automatically when I fetch an `Order`, but I'm only getting the `Order` data without the `OrderItems`. I've set up lazy loading by installing the `Microsoft.EntityFrameworkCore.Proxies` package and configured it in my `DbContext` like this: ```csharp protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) { optionsBuilder.UseLazyLoadingProxies() .UseSqlServer("YourConnectionString"); } ``` My `Order` class looks like this: ```csharp public class Order { public int OrderId { get; set; } public ICollection<OrderItem> OrderItems { get; set; } } ``` And the `OrderItem` class is defined as: ```csharp public class OrderItem { public int OrderItemId { get; set; } public int OrderId { get; set; } public Order Order { get; set; } } ``` When I make a request to my API endpoint to get an `Order` by ID: ```csharp [HttpGet("{id}"] public async Task<ActionResult<Order>> GetOrder(int id) { var order = await _context.Orders.FindAsync(id); return order; } ``` I expected `OrderItems` to be included, but they’re not being loaded. I’ve also tried adding `[Include]` in my LINQ queries and ensuring that `OrderItems` is initialized in the constructor of `Order`, but none of those approaches worked. I checked the database and confirmed that there are indeed related `OrderItems` for the `Order`. The only warning I receive is: ``` Warning: Lazy loading is not enabled. To enable lazy loading, use the `UseLazyLoadingProxies` method when setting up your DbContext. ``` Can anyone guide to understand why lazy loading is not functioning as expected in this case? What would be the recommended way to handle this? I'm coming from a different tech stack and learning C#. Any ideas how to fix this?
