General ======= 1. Know the Language (not just the UI) 2. Debugging 3. Logging 4. Data Security 5. "Security Theater" (things that doesn't really work) 6. Data Access 7. Database Design C# Related ========= 1. The Language itself 2. Breakpoints 3. Know one good logger 4. Built in dependency injection 5. app settings.json 6. Nuget 7. Iconfigurations, Ilogger, Idisposable 8. Data Access 9. SQL design 10. Multiple User Interfaces

Thanks for sharing.

[@harag9]

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!

[@IAmTimCorey]

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

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

[@chrismolby3495]

Really good stuff as always just wish I could understand it

[@IAmTimCorey]

I have a lot of training on these topics on this channel.

[@kpg7882]

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.

[@IAmTimCorey]

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).

[@pastorrandy]

@@IAmTimCorey Or you could call the theories, principles.

[@hello-again6994]

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.

[@anandsutrave5607]

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

[@simon-white]

You might want to use different server instances as different environments e.g. dev, test, production

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.

[@Explorest]

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.

[@IAmTimCorey]

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/

[@coderider3022]

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.

[@cemkaya4448]

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 KZbinrs use Windows. That makes me think if it is a good idea to buy Mac silicon instead of Windows laptop. What do you think?

[@portismouth]

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

[@cemkaya4448]

@@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 :)

[@portismouth]

@@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 😉

[@cemkaya4448]

@@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 :)

[@portismouth]

@@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.

[@yogij17]

Great video Tim! But can you tell us how much should we charge the companies after learning all this 😂😂😂

[@IAmTimCorey]

Whatever they will pay you, then push for more.

[@oysteinsoreide4323]

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.

@@IAmTimCorey Yeh ! But there must be some clue

[@oliverabrahamhamburg]

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".

[@terry.chootiyaa]

@Oliver Abraham *Not really, it's more of the case of at what point should you use a high note && || a low one ☺*

[@IAmTimCorey]

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.

Documentation? What is this thing you speak of?

[@coderider3022]

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.

[@IAmTimCorey]

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.
