使用workService集成SqlSugar报错

使用WorkService 集成Furion后，想使用SqlSugar进行数据库访问，在Program中配置如下
```
public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .Inject()
                .ConfigureServices((hostContext, services) =>
                {
                    services.AddSqlSugar(new ConnectionConfig
                    {
                        ConnectionString = $"{App.Configuration["ConnectionStrings:SqlServerConnection"]}",//连接符字串
                        DbType = DbType.SqlServer,
                        IsAutoCloseConnection = true,
                        InitKeyType = InitKeyType.Attribute//从特性读取主键自增信息
                    });
                });
    }
```
在Worker中使用如下：
```
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            while (!stoppingToken.IsCancellationRequested)
            {
                await SpareTime.DoAsync(1000, () =>
                 {
                     using (var scope = _scopeFactory.CreateScope())
                     {
                         var services = scope.ServiceProvider;
                         SqlSugarClient db = services.GetService<SqlSugarRepository>().Context;

Log.Information("1111111111");
                     }
                     _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
                 },stoppingToken);
            }
        }
```
运行到SqlSugarClient db = services.GetService<SqlSugarRepository>().Context;这一行报错
System.NullReferenceException:“Object reference not set to an instance of an object.”

Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetService<T>(...) 返回 null。
请老师指点一下。
