Why I can see 360px resolution only. am I missing something? hard to read the code from the blurred fonts

[mannetjie]

thank you it was very informative. your code is always so nice and clean, easy to understand. tip: i assume you have already changed or removed the connection strings to your service bus / message broker, as the shared key was exposed in the video 🙂.

I think the scenario you took with ConfigurationProviderBase class is not an actual scenario of inheritance

I do not want to sound mean at all but you should articulate better. It sounds like you are talking with almost your mouth closed and it's hard to understand you.

Change your font and vs theme it's highly irritating 😐
