i'm coding like below
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<SchoolContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddDatabaseDeveloperPageExceptionFilter();
services.AddControllersWithViews();
}
but i got a error message
Error CS1061 'IServiceCollection' does not contain a definition for 'AddDatabaseDeveloperPageExceptionFilter'
and no accessible extension method 'AddDatabaseDeveloperPageExceptionFilter' accepting a first argument of type
'IServiceCollection' could be found (are you missing a using directive or an assembly reference?)
