Thanks for sharing.
Good point about learning more than one tool that does the same thing - e.g. logging - log4net, nlog etc. You might move from one company to another and the 2nd company uses logging just not the same one you used at the previous company.
Great answers for the up and coming devs out there!
I agree. Thanks for sharing.
Logging is not as easy as it seems with framework now available. Best logging does not impact production env if it is turned off or levele is > Error, it does not impact website with milion of users requests in prod until you need analyze problem. Logging is quite hard to do right. Log only usefull infos, properly structured, level structured. Usefull logs are hard no matter what framework do you use. They must be usefull more then large :-D
Great stuff! Thanks Tim!
You are welcome.
Thanks Tim for your valuable suggestions.
You are welcome.
each time a new video will be released , I feel the upgrade of my view BW ,thank you Tim 🙂
You are welcome.
Always great advices!
Thanks!
I'm feeling this is not relating to techniques but some general subjects you should know. Programming techniques for me are: XP programming, pair programming, SOLID, KISS, DRY etc.
That's the tricky bit of trying to call them techniques (the word used in the question, which is why I used it). The items you mentioned are more principles (theory). I talked more about practical implementation. For example, dependency injection is a way to implement the D in SOLID (they aren't the same, but I explain that in my SOLID videos).
@@IAmTimCorey Or you could call the theories, principles.
@@pastorrandy 🤤 did he not do that in his comment? The words are right next to each other: "principles (theory)"
These topics makes an excellent rubric for questions to ask a candidate during a technical interview :)
They would.
Do you recommend focusing on clean code aspects and techniques?
Or focusing on optimization for time and space consuming ?
Can you please conclude your answer based on the chance of getting a job opportunity within a great company
Loved it bro👍🏼
Thanks!
Hello Tiim Corey,
Logging is something I have been struggling to implement in my applications. Is a there a standard way to do it or better way to implement it. Please a little bit of strategies to implement logging in applications will be appreciated.
Thank you.
Thanks for the suggestion. Please add it to the list on the suggestion site so others can vote on it as well: suggestions.iamtimcorey.com/
Worked, thx
You are welcome.
Really good stuff as always just wish I could understand it
I have a lot of training on these topics on this channel.
Hey there, Kudos to your great efforts in this channel.
I am a new sql learner with simple enquiry.
I learned that an sql instance is equivalent to an sql server installation on a machine.
Why i may need to install several instances on the same machine?
Thanks for taking time of my enquiry.
may be you want to test out different versions of sql server to try out new features, for that you don't want another machine just for trying out things
You might want to use different server instances as different environments e.g. dev, test, production
Is there a video you recommend that cover all these debugging techniques? Tried to find one on your channel but had no luck :)
Thanks as always for the amazing content 👏
Here is an older video: czcams.com/video/_YoKJwSzZOg/video.html
It is probably time for a refresh but this covers the most common things you can do.
You are the best, Tim 🙏🏽
Save game serialization threats are apparently one of the most common threat vectors how source code gets stolen, some malicious actor makes a fake bug report and submits a save with a malicious payload.
Could you say about micro ORM and its importance? Can explain Entity framework vs Dapper in core. When should I use Dapper?
He has already
@@CripplingDuality Other than Dapper which micro orm is there?
Here is a video on Dapper: czcams.com/video/Et2khGnrIqc/video.html
Here is a video on EF: czcams.com/video/qkJ9keBmQWo/video.html
You forgot about front end stuff like html js css... because I am a mid to backend but great on knowing your database (ooops, data structures too) which I do and interface with most of the time
This isn’t a comprehensive list of everything you should know, it was limited to techniques I think every developer should know.
I just want to thank you tim , bcuz of that dapper micro orm video i've implemented in project within our organization, so thank you once again
You are welcome.
Kindly have an episdoe answering this specific question:
How do I structure my C# source code repository ?? Please don't answer "it depends" --- just give your general throughts/guidlines/pitfalls etc.
For example : what folders should I generally have in my project root directory --- /src , /tests, /docs, ?? ... how do I then structure subfolders of those folders and so on. What files (other than .cs, .sln, or .csproj files) must/should go in project root --- and where if not project root.
Thanks for the suggestion. Please add it to the list on the suggestion site so others can vote on it as well: suggestions.iamtimcorey.com/
Answer is it should grow and evolve with the app if you can refactor it. There is no right answer and it does depend on things. As long as you enforce a 1 thing / type per file you can move things around. Having interfaces allows you to move files across projects. I recommend Steve ardalis clean architecture as a starting point, try to identify features in your all than can potentially be made into libs and brought in via nice service collection extensions.
*Tim in programming why isn't there a "SoWhat" condition like for,if, &&.....* 😁👍
Hi Tim!
Thanks for covering another great topic.
I have a different question. I need an laptop. I consider to buy a new m1 mac for using .Net development as an self taught learner. However, I realize that you and other .Net CZcamsrs use Windows. That makes me think if it is a good idea to buy Mac silicon instead of Windows laptop. What do you think?
Not Tim... but hope this helps. It depends on what you're used to - if you're used to Windows, stick with that. The Intel chips are just as good for most things and, for what it's worth, there are still things that are not compatible with Apple Silicon. You're also in trouble with Apple Silicon if you need to have more than one version of .NET on your machine. Finally, if you ever want to use Visual Studio the Mac version isn't as good as the Windows version. All that being said, you can make it work but you might run into some annoying obstacles with Apple Silicon
@@portismouth Thanks for the answer. As much as I search, Rider can be a solution for IDE. However, developing app on Windows seems easier than on Mac. I bought Mac :)
@@cemkaya4448 congrats! I personally have an M1 MacBook Pro. I love the machine. Anything I need to to do on windows I just run on parallels 😉
@@portismouth Yeah, it was also a good advantange which helped me to buy M1. However, I think MSSQL cannot be run on ARM processor. It can be problem for me because I am newbie.
Another thing makes me confuse shortcuts. I get used to Windows shortcuts. If I start working in a company, I think they might work with Windows. Since shortcuts are different, it can make problem all time switch. Do you have experience such as problem :)
@@cemkaya4448 I can run SSMS on a Parallels instance no problem. In fact I do it frequently.
Re: shortcuts - you get used to switching back and forth. It's a little like being bilingual... just with your fingers, it just takes some time and practice. Good luck on your coding journey! It was life changing for me.
versioning!
Yep.
*Tim did you mean any SQL server or MICROSOFT MS-SQL server ?*
Microsoft SQL.
I need a video related to microservices tim if you know the subject please release a video about microservice
It is on the list. I've already covered a few topics, including Azure Functions, Web API, Minimal APIs, MongoDB, and more. I'm still working on more content, but the term "microservices" is like saying "building a house". There is a LOT of small parts that add up to the whole.
Refactoring.
Version control. You must know how to use Git.
Definitely.
beat me to it (by 5 days :))
High Cohesion
Low Coupling
TDD
All good things.
Great video Tim! But can you tell us how much should we charge the companies after learning all this 😂😂😂
Whatever they will pay you, then push for more.
We are obligated to teach ourselves new things as professionals. We got to keep our salary I guess if you actually do what you are supposed to. And if you deliver better quality as a result of it, then maybe we get a raise. But they want results. Knowledge doesn't automatically gives better results.
Unit Testing
Yep, that's a good one.
Tim, I love you
I totally understand. Don't focus on the paid content. The purpose for the paid content is to fund more free content here on CZcams and on the web. There are over 450 videos here on this CZcams channel to help you become a skilled developer and more are added every week.
@@IAmTimCorey Thanks for such a great labor!
Big fan here.
Some day I'll pay for everything I received, so you can keep helping others.
@@eduardrivas6964 You don't need all the courses at once, depending on your skill and what your interested in just go for the ones as and when you can. Tim has a ton of great free content on the site as he mentioned, but from someone who has bought a few of his courses I can certainly say they are worth it in the long run, and if it helps you to get a job or promotion, then that's already paid for the course. But yes, check out the free stuff here!
@@harag9 Hehe I know I don't need all the courses, but the ones I want are just really expensive for a latam budget. 400$ is even higher than the minimum wage of the entire region.
*Tim the biggest problem for newbie programmers is we struggle to understand WHEN we should/could use loops, conditionals, ..... for example when to use a IF statement vs ELSEIF, or when to use the correct loops..FOR. ...can you make a video to explain this 👍*
That comes from experience, which comes from practice.
@@IAmTimCorey Yeh ! But there must be some clue
There are no strict rules beginners could follow, because the question is wide. It sounds to me like a musician asking "when should I play which note".
@Oliver Abraham *Not really, it's more of the case of at what point should you use a high note && || a low one ☺*
I think the analogy is sound (pun intended). In order to learn how to write code, you have to experience it and try. There aren't set scenarios that require a certain tool. Every situation will be different. That's why we say "it depends" a LOT. It takes experience in order to know when each item is useful.
magnetometers? :)
Cool, but no.
make a good soft
What does that mean?
The big one missing is making coffee.
I'm not a coffee drinker, so I missed it. 😆
Monthly pass is disabled tim
It opens a few times per year. If you are on the mailing list, you will be notified when it next opens up.
It's all data?
Always was...
Absolutely.
@@IAmTimCorey IDK if you remember my comments, but I got into programming through learning to mod games, and one of the first things I built was a program to archive files the way that the games I mod archives them.
It's all data! IDK how to express it, but data is also the most interesting part about what I do. I have a bunch of data, and I have to figure out what it does and what it goes to.
Number one generic rule, you need to know how to read documentation
Documentation? What is this thing you speak of?
Lost some weight Tim? ;)
Jesus is the Way

Disagree on the sql side, clear that anyone in the profession are so much better at web and ui work at the expense of their db knowledge when compared to the vets which were forced to put their db in the centre of everything. Also, bad sql and table design isn’t an issue like it was 20yrs ago, compute , ram and disk speed negated the issue.
I strongly disagree with this take. Your data is the center of every application, including web applications. Not knowing how to properly work with data from the database to the UI and back hampers your ability to make good choices in the front-end. As for bad SQL design not being an issue anymore because computers are better, that's a hard no. Poor database performance can and does absolutely sink apps. Amazon found that a 100ms reduction in page load speed cost them 1% in sales. The thing is, that isn't exclusive to Amazon. That's something that happens with sites of all sizes. Guess where most of the performance gains and losses are on a website? In the database.
