Almost all azure-cache-redis-samples does not work correctly

Salam 26

Hi, Can you please double check if the samples can work correctly. Already, fo ASP sample, in VS 2022 after struggling with missing bundles/scripts not found virtual directory, it fails on the line 149 of
azure-cache-redis-samples of redisConnection.cs
I followed then instructions for "cache-web-app-aspnet-core-howto" it builds and run then when clicking on "Azure Cache for Redis Test", I get

In the ASP sample, execution jumps from line

await redisConnection.ForceReconnectAsync(initializing: true);

right away to

await oldConnection?.CloseAsync();

with the following error on line 149 :

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.

Geetha I cloned the new version, opened asp in VS2022, after struggling with Newton.json versions, I managed to build with version 12.1 of Newton. Again, running the application it fails on the bundlesconfig as no bundles directories are there, not sure why you keep this while it is not avialable/used in the code

2nd, after commenting the lines bundle.add in bundleconfig, I get

@Salam Thanks for the response and providing the screenshot, we have merged some changes to resolve the Newton.json version issue and defined the Javascript bundle inline.
Regarding your second screenshot, please ensure you have configured your cache as defined here: Create an ASP.NET web app with Azure Cache for Redis | Microsoft Learn

Hi, anonymous user I am unable to replicate the issue on my machine. Please ensure your CacheSecrets.config file follows the following format:

<appSettings>
<add key="CacheConnection" value="<DNS_NAME>.redis.cache.windows.net:6380,password=<PASSWORD>,ssl=True,abortConnect=False"/>
</appSettings>

In fact Geetha, it was an issue with

DigiCert Global G3 CA Root

I came across this blog

Azure Cache for Redis TLS: Upcoming migration to
https://techcommunity.microsoft.com/t5/azure-developer-community-blog/azure-cache-for-redis-tls-upcoming-migration-to-digicert-global/ba-p/3171086

After reading this post, I downloaded "DigiCert Assured ID Root G3", installed it on my win 10 box, rerun the app and HOP everything worked fine.

Van you please tell me is there a post that explains how this apps works/architectured?

Thanks again for your help
