The error message in your screenshot indicates two main issues when running dotnet ef migrations add for multiple DbContexts:

Entity Framework Tools Version Mismatch
- The EF Core tools version (8.0.8) is older than the runtime version (9.0.8).
- Solution: Update your EF Core tools to match the runtime version. Run:

dotnet tool update --global dotnet-ef

 Or, if you use a local tool manifest:

dotnet tool update dotnet-ef

Unable to Create a DbContext Instance
- The error says it cannot create a DbContext of type WaveSecureVeltris.EntityFrameworkCore.ConfigDbContext.
- This is usually caused by a missing or misconfigured IDesignTimeDbContextFactory<ConfigDbContext>.
- Solution: Ensure you have a correctly implemented ConfigDbContextFactory in your EntityFrameworkCore project. The factory should look like:

public class ConfigDbContextFactory : IDesignTimeDbContextFactory<ConfigDbContext>
     {
         public ConfigDbContext CreateDbContext(string[] args)
         {
             var optionsBuilder = new DbContextOptionsBuilder<ConfigDbContext>();
             optionsBuilder.UseSqlServer("Your_Connection_String_Here");
             return new ConfigDbContext(optionsBuilder.Options);
         }
     }

Make sure the connection string is valid and the factory is in the same assembly as your DbContext.

Summary of Steps:

Update EF Core tools to match your runtime.
Double-check your IDesignTimeDbContextFactory implementation and connection string.
