public void ConfigureServices(IServiceCollection services)
        {
            var con = _configuration.GetConnectionString("telemetry");
            services.AddDbContext<TelemetryContext>(options => options.UseSqlServer(con));
}

TelemetryController

[ApiController]
    [Route("api/[controller]")]
    public class TelemetryController : ControllerBase
    {
        private const int Interval = 15;
        private readonly TelemetryContext _ctx;
        public TelemetryController(TelemetryContext context)
        {
            _ctx = context;
        }
