MongoDB.Driver C# auto expire documents


MongoDB.Driver C# auto expire documents



I am inserting documents into a collection and have a field called ExpireWhen. I would like to automatically remove those documents when the date has expired. I tried looking around but was not able to find information using the mongo db driver for c# version 2.6.1



I tried the following but it doesn't seem to do anything.


this.CacheItemRecords().Indexes.CreateOneAsync(
Builders<CacheItemRecordEntry>.IndexKeys.Ascending(_ =>_.ExpireWhen),
new CreateIndexOptions { ExpireAfter = new TimeSpan(0, 0, 0) }
);
