Something new to learn...

C#

Hi all,
I am currently searching for some knowledge or tools that I could acquire to improve myself a little bit.

Last thing I played with a lot was the DataFlowLibrary from Microsoft, which I enjoyed quite a lot.

I also currently play along with ML.NET, but not too much.

Do you have any recommendations on what could be a good add-on to my programming skills?


Thanks ppolymorphe for pointing out that I forgot to post my background.
I writing C# applications for about 20 years now and I am pretty familiar with the concepts of programming. I stumbled over a lot of great tools like the TPL or most recently the DataFlowLibrary and realized that there must me interesting, yet useful tools out there that I might have missed (family binds a lot of my time I formerly used to try out new things, so I have to be more efficient lately in finding things I want to spend my time with).
I did Java/C++ in the past but moved on to C# as soon as it came out many years ago :)
Databases, Web, Services... all covered (more or less).


The reason for searching new topics to learn is actually (I might repeat myself here) is finding out about the DataFlowLibrary...
Have you stubled over some topics where you just thought "Danm... how could I miss that?"... These are the topics I might be interested in...
I hope that helps a little :)



Any recommendations are highly appreciated,

best regards
Andy

What I have tried:

As already mentioned I digged deeper into DataFLowLobrary, ML.NET, TPL and its "friends".
Azure and it's "Whatever as a Service" was also something I did quite some projects with in the near past.
