1 year ago 2.6.66 is a year old; a number of bugs etc have been fixed in that time - possibly I wonder if this is related to the GC fix that was in one of them (I'm not going to click into each to find which exactly).
Try with NuGet latest; if it happens with latest: this might be interesting. But until you've tested with latest, I'm going to assume it is already fixed.

var cacheDatabase = await Task.FromResult(wrappedConnectionMultiplexer.GetDatabase()); await cacheDatabase.StringGetAsync(string key);
`
But if the key doesn't exist or account name is incorrect. I see different behavior in .NET framework 4.6.1 and .NET 6.0
.Net framework 4.6.1 StringGetAsync() will immediately return Or connection exception if account is incorrect in connection string.
.net 6.0 StringGetAsync() doesn't return (until the app monitoring code cancel the request after application timeout of 10 sec).
in both .NET versions, StringSetAsync is executed with CommandFlags.FireandForgot and call immediately return.
Question:
- Is this difference expected or there is different way to use redis in 6.0.
- why ConnectionFailed event is not called (nothing writtern to AI logs)
