如何从F#调用Redis StringSet()

Question

我正在使用StackExchange.Redis来访问Redis实例.

我有以下工作C#代码:

public static void Demo()
{
    ConnectionMultiplexer connection = ConnectionMultiplexer.Connect("xxx.redis.cache.windows.net,ssl=true,password=xxx");

    IDatabase cache = connection.GetDatabase();

    cache.StringSet("key1", "value");
}

这是我希望的等效F#代码:

let Demo() =
   let cx = ConnectionMultiplexer.Connect @"xxx.redis.cache.windows.net,ssl=true,password=xxx"
   let cache = cx.GetDatabase()
   cache.StringSet("key1", "value") |> ignore

但是这不会编译 - '没有重载匹配方法StringSet'.StringSet方法需要RedisKey和RedisValue类型的参数,并且在C#中似乎有一些编译器魔法将调用代码中的字符串转换为RedisKey和RedisValue.F#中似乎不存在魔法.有没有办法达到同样的效果？

这是工作代码,非常感谢@Daniel:

open StackExchange.Redis
open System.Collections.Generic

let inline (~~) (x:^a) : ^b = ((^a or ^b) : (static member op_Implicit: ^a -> ^b) x)

let Demo() =
   let cx = ConnectionMultiplexer.Connect @"xxx.redis.cache.windows.net,ssl=true,password==xxx"
   let cache = cx.GetDatabase()

   // Setting a value - need to convert both arguments:
   cache.StringSet(~~"key1", ~~"value") |> ignore

   // Getting a value - need to convert argument and result:
   cache.StringGet(~~"key1") |> (~~) |> printfn "%s"
