Handling Nullable Properties in Entity Framework Core with C# 10
I'm stuck on something that should probably be simple. Can someone help me understand I'm working on a project and hit a roadblock. I'm stuck on something that should probably be simple... I'm currently working with an scenario when trying to save an entity with nullable properties using Entity Framework Core 6 in my C# 10 project. I have the following model: ```csharp public class Product { public int Id { get; set; } public string Name { get; set; } public decimal? Price { get; set; } // Nullable property public string Description { get; set; } } ``` When I try to insert a new `Product` instance with a `null` price like this: ```csharp var newProduct = new Product { Name = "Sample Product", Price = null, // Intentionally setting to null Description = "This is a sample product." }; using (var context = new MyDbContext()) { context.Products.Add(newProduct); context.SaveChanges(); } ``` I am getting the following behavior: ``` The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Products_Orders". The conflict occurred in database "MyDatabase", table "dbo.Orders", column 'ProductId'. ``` The `Product` entity is supposed to be independent of any foreign key constraints because of its nullable properties. I checked the relationships in my `DbContext` configuration and confirmed that the `Product` entity does not have a required foreign key reference. ```csharp protected override void OnModelCreating(ModelBuilder modelBuilder) { modelBuilder.Entity<Product>() .HasKey(p => p.Id); modelBuilder.Entity<Product>() .Property(p => p.Price) .IsRequired(false); // Marking as not required } ``` I also verified that my migrations are up to date. Can anyone explain why I am working with this foreign key violation when the `Price` property is nullable and should not affect the insert? Is there something I might be overlooking in the configuration? Any help would be greatly appreciated! My development environment is Ubuntu. For context: I'm using C# on Ubuntu. This is my first time working with C# latest. I'd really appreciate any guidance on this. Is this even possible?
