I've tried everything I can think of but Quick question that's been bugging me - I'm working on a project and hit a roadblock. I've been banging my head against this for hours. I am working with a .NET 6 Web API project in Visual Studio 2022 where I'm using Entity Framework Core for database interactions. After making some changes to my model classes and running the command to add a new migration, I encountered an unexpected behavior: `The migration is not compatible with the current model`. Iโ€™ve tried cleaning and rebuilding the solution, as well as removing the previous migration files to see if that would help, but the behavior continues. Hereโ€™s a snippet of my `DbContext`: ```csharp public class MyDbContext : DbContext { public DbSet<Product> Products { get; set; } public DbSet<Category> Categories { get; set; } protected override void OnModelCreating(ModelBuilder modelBuilder) { modelBuilder.Entity<Product>() .HasKey(p => p.Id); // Additional configurations... } } ``` I modified the `Product` class recently: ```csharp public class Product { public int Id { get; set; } public string Name { get; set; } public decimal Price { get; set; } public bool IsAvailable { get; set; } // New property added } ``` After adding the `IsAvailable` property, I ran the migration command: ```bash Add-Migration AddIsAvailableToProduct ``` This resulted in the compatibility behavior. Iโ€™ve also checked that my `Startup.cs` is properly configured for database context options: ```csharp public void ConfigureServices(IServiceCollection services) { services.AddDbContext<MyDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))); } ``` Could this be related to the way I've set up my migrations? Iโ€™ve also verified that the database schema is in sync with the current model, but it seems like EF is not recognizing the updates correctly. Any insights or suggestions on how to resolve this scenario would be greatly appreciated. How would you solve this? My development environment is macOS. I'd really appreciate any guidance on this. What are your experiences with this?
