Accepted Answer

When working with the StackExchange.Redis library in .NET, the `GetDatabase()` method returns an instance implementing the `IDatabase` interface. In a cache-aside pattern, invalidating the cache upon data modification requires removing the stale key so that subsequent reads result in a cache miss and fetch the fresh data from the database. The correct method to remove a key from the cache in the StackExchange.Redis API is `KeyDelete`.
