I have an ASP.NET Core 8 project with Entity Framework Core. The connection string is taken from web.config in the root folder. While debugging in Visual Studio 2022, I enabled Hot Reload. I have figured out way to refresh DbContext when hot reload is triggered.

I use this code:

[assembly: System.Reflection.Metadata.MetadataUpdateHandler(typeof(HotReloadManager))]
namespace xxx
{
    internal static class HotReloadManager
    {
        public static void ClearCache(Type[]? types)
        {
            // Clear any caches if needed
        }

        public static void UpdateApplication(Type[]? types)
        { 
            using var context = new xxxDbContext();
            context.Database.EnsureCreated();
        }
    }
}

It works fine while hot reloading. DbContext is refreshed. Then the next thing is when I edit connection string in web.config, I find that this will not trigger hot reload. How can I achieve that?
