Why does LINQ have so many ways to return an element?
Hi, I don t see where in your code the log method is called ?
What is the real benefit of using an error handler compared to a exception middleware?
why having Produtct and GetProduct??
Great informative video, keep it up!
thank you sir
Question: when we use [fromquery] but i need to recive more than one parameters, do a have to create a class? or in a method i can declare [fromquery] many time?
Nice and useful. Thanks.
Thanks for the help. You're a savior.
Great quick explanation!
thank you Sir
Very nice video. very instructive content. Thanks
Thanks. Glad you found it useful.
Doubt please , Did we use same YAML file tasks for .NET and .NET Core , Is they are same or different .
You can't use the DotNetCoreCLI@2 for .NET Framework tasks. That's specific to .NET Core. I think you can use VSBuild@1 for .NET Framework tasks.
very well explained, I have little issue with pronunciation and accent as I am from different country, but very nice information, sir !!
Glad it was helpful!
I love your channel, I'm living in Portugal, but I'm looking for new jobs in 🇬🇧.
Best bet will be to relocate to the UK. You'll have a better chance of getting a job.

You sir, are brilliant! Thank you
Great tutorial, but missing IOptionsMonitor.
Nope. Maybe it is helpful in better templating, or helping juniors in setting up schoolbook application skeletons but it is beyond clueless in finding bugs, optimizing logic or generating custom algorithms. We already have non-LLM generative tools since decades, which are precise and helpful, but you only use them for specific application layers like entities or persistence. 101 in optimizing & debugging : comprehend your code. 101 in having more capabilities: clients want more and richer features
Thanks David, fantastic video. One of our front-end developers who uses Linux and Vscode is looking into moving into some backend stuff - do you have any hint for using custom nuget feeds (authenticating from Azure artifacts) and using Default Azure credentials on Linux for Azure Key Vault? Thanks
Why don't you use releases?
Releases is the old way of doing it.
@@RoundTheCode Maybe for small-scale projects. But for an Azure DevOps implementation housing 50+ large scale enterprise repos, I think standard release pipelines are the way to go. Did microsoft come out with any docs/statements recommending to use only pipelines, not releases anymore?
I gave C# on VS Code a real try at a big work project, 8 months using this tool stack, it's extremely far from ready for any usage. The LSP is slow, eats up a lot of resources (both RAM and CPU), full of bugs, and needs to be restarted from time to time because it decides to stop working randomly, therefore, taking full minutes to reload the projects again.
true
I'm sorry I ever considered this ecosystem to find a job. As for you mr Round the code thaNks for the amazing video!! The tool failed me, not your content.
Thanks for the comment.
.NET Developers who don't use Rider are at a disadvantage.
Never used it personally, so I can't comment. But I have heard good things about it.
Step 1: install Linux Step 2: Install NeoVim Step 3: Code like a real man
Can't say I've used NeoVim. What's it like?
It's a bare-bones text editor. It's efficient in its core, use a set of movement called “VIM motions” that are (very often) useful for manipulating text (and code). Uses a language to manipulate itself (instead of JSON), so you can change and modify the editor to suit your needs.
Aaahhh almost forgot, when youststt using neovim you can say “I use VIM btw” 😊
Thankyou for this. I had a very bad time with using C# from the command line/VS Code when I had to use C# for a similar web service thing. The Visual Studio IDE has infected the C# / dotnet languages with a method of working that is very UI based. I am simultaneously impressed and disgusted that a CLI would be used to create a class. I would never have thought to try that. Obviously productivity benefits... but oh man too bad if you dont like Microsofts way of doing things i guess.
The same thing stood out to me. It never would've occurred to me to use a cli tool to create a class. I guess Microsoft wants to beat sun microsystems at creating the most convoluted boiler plate machined ever to boilerplate 😂
You can use the application to create a class etc. using Solution Explorer in VS Code if that's your preferred choice. Here's a video with more detail on it: czcams.com/video/r4WrDfuDT24/video.html
Will this work with net framework 4.0?
Yes, but you have to install the Microsoft.Bcl.Async NuGet package.
Nlog does a good job. and easy.
Serilog also does a good job.
Aspnet .core logging suck no offense. its not straight forward when u want to log a file.
With this method When I’m execute my API with postman I have to set header to Authorization Basic base64username&password Right?
You need to base 64 encode it in this format. {username}:{password} So you should be passing in a base64 hash as part of the Authorization header.
how can we find device details, like parsing from user agent .. i want to implement the new device-found functionality like google offers and send MFA on the app...
I'm not sure, but I might look into it.
Awesome. Thanks for this
No problem!
awesome tips :D
Glad you like them!

No, because you would be able to change the price.
Thank you. Clear and simple. Nice explanation. Keep going
Thank you, I will
how can this made cross platform? any nuget package to have a host that is not windows specific? great video btw, concise and to the point. thanks
good video gave good insight on how the code works for newbies
Glad it helped
offset=2:50 as shown the category input parameter should be of type Category (i.e. that SHOULD not be null) public string? GetCategoryName(Category category) alternatively you could explicitly specify method declaration to accept nullable params with one of public string? GetCategoryName(Category? category) public string? GetCategoryName([AllowNull] Category category) so compiler would alert dodgy statements e.g. category.Name would be squiggled to warn dev to reconsider, e.g. Severity Code Description .. Warning CS8602 Dereference of a possibly null reference. Certainly your code _could_ have an early guard statement as safety-check (despite declaring "Category" as non NULLable), but I find that inconsistency to be a code-smell and I prefer using proper NRT semantics. Current project templates now include <Nullable>enable</Nullable> in generated .csproj to discourage NULL accidents.
offset=2:21 for "can not allocated .." read "can not allocate .."
Lots of great tips here that I missed in recent .NET/C# updates. Thanks!
awesome video ! use this for reference at work
Great!
