Start with quickstart/aspnet/ContosoTeamStats/RedisConnection.cs and inspect the ConnectionMultiplexer.ConnectAsync call alongside the working Connect call. Reproduce the reported behavior after gathering the missing OS, version, logs, and minimal steps; done means the async connection behavior is explained and the sample's documented behavior is verified.
