Issues with EFCore

Hello everyone, I am trying to use ApplyConfigurationsFromAssembly but it seems to not be finding any configurations

        modelBuilder.ApplyConfigurationsFromAssembly(typeof(UserConfiguration).Assembly);

        modelBuilder.ApplyConfigurationsFromAssembly(typeof(UserConfiguration).Assembly);

Instead, I have to apply configurations like this

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // Call the base OnModelCreating
        base.OnModelCreating(modelBuilder);
        
        new PermissionConfiguration().Configure(modelBuilder.Entity<Permission>());
        new RoleConfiguration().Configure(modelBuilder.Entity<Role>());
        new UserConfiguration().Configure(modelBuilder.Entity<User>());
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // Call the base OnModelCreating
        base.OnModelCreating(modelBuilder);
        
        new PermissionConfiguration().Configure(modelBuilder.Entity<Permission>());
        new RoleConfiguration().Configure(modelBuilder.Entity<Role>());
        new UserConfiguration().Configure(modelBuilder.Entity<User>());
    }

and to apply them in correct order or migrations won't work, I am not sure what could be causing this issue, I have a clean architecture solution split into multiple projects. Could anyone point me to the right direction?

what makes you say this?

because when I don't do this

        new PermissionConfiguration().Configure(modelBuilder.Entity<Permission>());
        new RoleConfiguration().Configure(modelBuilder.Entity<Role>());
        new UserConfiguration().Configure(modelBuilder.Entity<User>());

        new PermissionConfiguration().Configure(modelBuilder.Entity<Permission>());
        new RoleConfiguration().Configure(modelBuilder.Entity<Role>());
        new UserConfiguration().Configure(modelBuilder.Entity<User>());

I get error that it can't link 2 entities to its foreign keys

where are you calling modelBuilder.ApplyConfigurationsFromAssembly()?

altynOP•13mo ago

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // Call the base OnModelCreating
        base.OnModelCreating(modelBuilder);

        // TODO: figure out why application from assembly doesn't work
        // modelBuilder.ApplyConfigurationsFromAssembly(typeof(UserConfiguration).Assembly);
        new PermissionConfiguration().Configure(modelBuilder.Entity<Permission>());
        new RoleConfiguration().Configure(modelBuilder.Entity<Role>());
        new UserConfiguration().Configure(modelBuilder.Entity<User>());
        new LogConfiguration().Configure(modelBuilder.Entity<Log>());
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // Call the base OnModelCreating
        base.OnModelCreating(modelBuilder);

        // TODO: figure out why application from assembly doesn't work
        // modelBuilder.ApplyConfigurationsFromAssembly(typeof(UserConfiguration).Assembly);
        new PermissionConfiguration().Configure(modelBuilder.Entity<Permission>());
        new RoleConfiguration().Configure(modelBuilder.Entity<Role>());
        new UserConfiguration().Configure(modelBuilder.Entity<User>());
        new LogConfiguration().Configure(modelBuilder.Entity<Log>());
    }

inside my DbContext

public class DashboardDbContext : DbContext, IDashboardDbContext

public class DashboardDbContext : DbContext, IDashboardDbContext

I also tried calling base on bottom, also doesn't work Inside the Dashboard.Persistence project\
