我有一个基于 F# 的应用程序，我使用 EF-Core 和 MySQL (Pomelo.EntityFrameworkCore.MySql)。我有一个async方法可以更新数据库（MySql）中的数据

let updatePlayerAchievementsAsync (logger:ILogger) (ctx:ReportCacheDbContext) (id: int) = async {
  let! account = ctx.AccountCaches.FirstOrDefaultAsync(fun e -> e.AccountId = id) |> Async.AwaitTask
  if account <> null then
    account.State <- "Closed"
    do! ctx.SaveChangesAsync true |> Async.AwaitTask |> Async.Ignore
    logger.LogInformation("Account{0} updated", id)        
}
