有没有办法使用F#记录类型来提取appsettings.json配置？

type DatabaseSettings = {
    Server: string
    Port: int
    Username: string
    Password: string
}

open Microsoft.Extensions.Configuration

let loadConfig() =
    let config = ConfigurationBuilder()
                    .SetBasePath(Directory.GetCurrentDirectory())
                    .AddJsonFile("appsettings.json", optional=true, reloadOnChange=true)
                    .Build()

    let databaseSettings = config.GetSection("DatabaseSettings").Get<DatabaseSettings>()

    databaseSettings

let config = loadConfig()
printfn "Server: %s" config.Server
printfn "Port: %d" config.Port
printfn "Username: %s" config.Username
printfn "Password: %s" config.Password
