includes the StackExchange.Redis client package. A variable named CacheConnectionConfiguration stores the
cache endpoint URL and the password to connect to the cache.
The application must store a user’s color selection by using the Azure Redis cache. The cached value must
expire after 90 minutes. You need to cache the user’s color selection.

Answer: 
Explanation:
Box 1: var cache = connection.GetDatabase():
Oncethe connection is established, return a reference to the redis cache database by calling the
ConnectionMultiplexer.GetDatabase method.Box 2: cache StringSet(“color”, colorSelection,TimeSpan.FromMinutes(90));
The TimeSpanFromMinutes method returns a TimeSpan that represents a specified number of minutes, where
the specification is accurate to the nearest millisecond.
Example: The following code snippet shows how to set an expiration time of 90 minutes on a key.
// Add a key with an expiration time of 90minutes
await cache.StringSetAsync(“data:key1”, 99, TimeSpan.FromMinutes(90));
