Hey @NickCraver , it looks like it's not an issue with the version or the command or anything, just a bit of weirdness in redis-io.

TL;DR: There's a missing line in a config file in the reids-io app that's causing that weirdness

Basically, the redis-io interactive uses a bit of tomfoolery to let you think it's a straight pass-through to redis, however it intercepts your commands and uses your sessionId to namespace all the keys you're interacting with from it. The reason for namespacing everything is so that when your session dies it can tare out all the keys you added to Redis, as you can imagine it's a security/stability concern to leave an open-ended terminal to Redis :). There's a config file (well it's code but let's call it a config file) that tells redis-io how to parse and namespace the arguments for each command. If the command isn't in that file it just assumes the command either doesn't exist or is explicitly in the don't-allow list. You'll notice that ZRANGESTORE isn't in there. I'll check with @itamarhaber why this is, it should be auto-generated by a script, but I think a confluence of events prevented it from making it in. Looks like the ZRANGESTORE command missed the train by a few weeks in redis/redis-io#226, which added all the 6.2 - looks like zrangestore was added a few weeks later in redis/redis/#7844 - also looks like there might be a bit of an issue with the script which should autogenerate everything (could just be my environment I'm very much not a rubiest but there are parsing issues from the commands.json file.

Regardless, if you add "zrangestore" => [:custom], to commands.rb and spin up redis-io it works as you'd expect:

So I wouldn't let this weirdness in redis-io dissuade you from including ZRANGESTORE in the library.

I'll track down how to fix the interactive :)

in the interim @danielgerlag - you can of course use the ad-hoc commands db.Execute/db.ExecuteAsync. In my experience they tend to work just fine, you don't have a particularly complicated result to parse as it just returns an int.

await db.SortedSetAddAsync("srczset", new SortedSetEntry[]
{
    new("one",1),
    new("two", 2),
    new ("three", 3),
    new("four", 4)
});

var numInSet = await db.ExecuteAsync("ZRANGESTORE", "dstzset", "srczset", 2, -1);

Console.WriteLine((int)numInSet);

var range = await db.SortedSetRangeByRankAsync("dstzset");

foreach (var elem in range)
{
    Console.WriteLine((string)elem);
}

does the job.

I'd be happy to open a PR for this if you'd like @NickCraver?
