Logging in .NET Core 3.0 and Beyond - Configuration, Setup, and More

Tim, this channel is an absolute gem. You're a great teacher and I recommend you to everyone asking for C# help.

"I don't like magic, when it breaks down you have to figure it out first before you can fix it"
ABSOLUTLEY YES.


ASP CORE is brilliant in how it works, but boy does this configuration through extension methods obscure how simple it actually works. Both the services collection and pipeline, the core components of how it works, get obscured.


Everyone creating anything serious shoud have a solid grasp of how the 'pipeline' (it's more of a trampoline) and the mvc routing mechanism work and how the classes it news up interact with the DI services. (maybe an idea for a video?)


It's probably less work to go down understand that than to stare at the magic show and keeping your fingers crossed. Once you get it it really is so simple and elegant.

Thank you for an excellent video @IAmTimCorey! My favorite part: 53:02 "Where do you go from here? Well, ...to start off with, you stop right here." :]

Tim, I've been using the basics in Serilog for quite a while and would love to see an in-depth discussion of the advanced features of Serilog. Thanks for the great videos!

For all tutorials I have watch, you are the one explain it line by line

[dalmirogranas]

I keep getting back to this video over and over. Content is solid ❤️

[TheChodex]

This is so much better then Log4Net in my opinion. Simple things like this are what made me fall in love with .NET Core. Everything I need just comes built-in!

[imanqoly]

My headache relieved after this video bless you

[sokkpupptz]

i watched the whole thing but didn't what i came for which was how to log to files n=but still worth watching - thanks

[wchishti]

Thank you for explaining all the behind-the-scenes logic. It was very helpful.

[bhoopendrasharma]

Thank you, Tim, for such informative video about .NET core ILogger, videos on Serilog and ApplicationInsights would also be exciting. Thanks again...

[LivingTheDream]

Very well explained, step by step and thorough. Answers all questions I would've had.

[austinhummel]

Thanks Tim, another incredibly useful breakdown!

[harag]

Great timing Tim, I'm learning Core 2.2 (don't use VS2019 yet) - Looking forward to watching this in a day or two. Thanks!

From now on, I'll just say For the Algorithm.
Cause I am tired of writing that you are an outstanding teacher.
