Hello everybody I'm Nick and in this video I will talk about source code analyzers also known as Roslyn analyzers. I will explain what they are, how they work, the forms they can have and how you can use them to write cleaner, better and safer code.

I forgot to mention it in the video but you can find more Roslyn analyzers here: github.com/Cybermaxs/awesome-analyzers
You can also search for "Roslyn analyzers GitHub" and you will find the most popular ones. People are creating some really good stuff. Don't forget to star their GitHub repos.

Hello Nick, further video creating analyzers would be awesome. Also, Rider centric tutorial would be good, as the one's I have seen have been Visual Studio-based. Further, some areas I would personally find helpful are how to efficiently distribute them with your solution (I'm guessing Nuget is the way forward here) and the foibles of how Rider interacts with Analyzers and it's own built-in one, code cleaning rules etc. I've found that this is one area the Rider has a fairly messy implementation on this front. Also, that touches on my final interest, do you have any best practices for distributing common code inside your organisation. I've seen Nuget suggested and equally frowned upon for this.
Roslyn analyzers are like Grammarly for coders.
So true.
so I'll be even better at copy/paste? Perfect. I'm not looking to increase my fundamental knowledge but instead to skate by at my day job being overpaid the entire time. It sounds like this is great for me, thanks for the feedback. /s
Just discovered your channel. Your every video is a top notch material. Amazing work!
Great video as always! I finally understood exactly what the enclosure is !
Great work Nick, Lots of value in your videos.
Yes I would like Roslyn analyzers videos.
Also, can you elaborate about how and what for do you use reflection.
Great video! Yes, I'd love to see one on how to write a source analyzer.
Thanks! it really helped me to get started programming!!
Absolutely fascinating!
Excellent video!!
Interesting topic. Never used it in live development yet.
I'd love to see how to write analyzers please do a video on this
Finally I found the video I wanted!! Thanks a lot!! Btw my rider in Linux shows reference not found when I compile (as a warning) but the alert is shown.
10:50 awesome content, mate!
There was a guy i met telling me about how hw makes boxes within boxes in C#. Now that sounds nice for a guy like me who can make boolean chip sets to accomplish 'almost' any task..
most code seems to be the same set up overall
true/fulse.
Light-up/black-out
cell groups. And.OR.XOR
But all over the place wich compared to physical boards/chips that lead into one another.. you can see how it gets confusing for someone like me. The box within box sounds nice for keeping track of group and function with an intangible :D
I would also appreciate having.a video about writing analyzars. Tx.
Bravo, keep on
I've been watching your vids for sometime now, I couldn't resist hitting the sub button for this vid
Hi Nick. Thanks for this video. Can you share a list of useful source analyzers, like you showed in the video? Are there many of them?
Ah damn I forgot to mention it on the video. There is a repo that contains a list of them here: github.com/Cybermaxs/awesome-analyzers but it's a bit outdated. It still contains many good ones.
Hello Nick,
In this video, you have shown 2 analyzers that are really interesting.
Are there any others that you would recommend?
Hello, Dear can you make a video tutorial about singleton, scope, and transient (which is better for.net core API)
Please adjust the font size/zoom levels, to comfortably watch the content on big screens.
Seems fine on my screen? Not having any issues.
Nah this is perfect zoom and font size when watching on a mobile device.
Hi Nick,
I just watched your video about IHttpClientFactory and was wondering - should i dispose instance of HttpClient from factory like this:
```
using var httpClient = httpClientFactory.CreateClient("Test");
```
or it does not matter cause of some handling in IHttpClientFactory or even we shouldn't?
Sorry that this is not in subject of this video, but it's the newest and there is bigger chance for reply ^^
I would say yes :)
As of November 2021 your example with Reflections doesn't work. I mean the analyzer doesn't highlight this field anymore (v 0.3.0)
I don't understand how to get that and use it. It's something like external software which u run during programming, or nuget package... Or maybe i should write it by myself. If there is answear
yes" for all question, i would prefer a complete package of this instead of writing it by myself
Can .NET analyzer/Roslyn analyzer be added to CICD pipeline?
If it is installed as a Nuget package then yeah
I see Nick uses "!." As and operator a lot. As I am still learning C#, what does this mean?
It means that this value will definitely not be null. I’m using it to suppress the warning for the video. In a realistic scenario you might wanna handle null appropriately
@@nickchapsas Thanks Nick!
I have found the videos super insightful and interesting. As a professional in another field that codes for a small team, they point out things I should look into to be better.
👍🏽
Nick, which language do you like to use more, Kotlin or C#?
I use C# waaaaay more. It's like a 95% C# 5% Kotlin. I only use Kotlin for personal random stuff and not for an actual professional purpose. I do enjoy it a lot though.
@@nickchapsas Nice, thanks. Do you mostly write cross-platform .net core code these days or do you write windows specific stuff still (wpf, iis web apps, ...)
@@petrzurek5713 crossplatform. I've only worked on windows specific stuff for 1 year right before .net core came out
Pleas make video on how to mak custom analyzers and more and more❤️
Can you write code that Cannot be decompile for security
That's impossible as far as I know.
You could make it much less readable tho.
Also, ANY scripting language (C#, VB, Java, Kotlin, JS, Python... ) is a bad idea if you are concerned about your code security.
As far i know only c++ makes it hard to reverse engineer the code.
@@igorthelight can you make video on reverse engineering in .net
@@sohampatel1063 Not only C++ but ALL programming languages that produce native binaries (C, C++, Rust, COBOL, Fortran, Pascal, Kotlin Native...)
@@ahmedkhudhair8035 Sadly, I can't say that I'm professional enough to make a video.
But I may recommend to try "Telerik JustDecompile", "JetBrains dotPeek" and "ILSpy".
Just play around with them and you will be able to decompile most .NET programs. To decompile more professional programs you will need more knowledge (Google Search is a good tool ;-) )
Make an analyzer that prevents my colleagues from using foreign language words instead of english in source code.
Best is two languages mixed in one property or function^^
It's called pull request rejected :)
You missed the opportunity to type ANALyzer
I am honestly very disappointed in this Video... I was actually expecting to see some actual code of an individual analyzer... not just examples for given ones...
