I like simplicity in Go and i wrote a big corporate app with it. I disagree with anyone that go would be slow for big and complex app but fast for simple apps. I agree that develop complex app in go is repetitive, but it is VERY fast. Maybe one of the cheapest in resources among apps that i wrote. And very stable, very error free. After project done, i almost never touch it again since no error. Smooth running for years, almost without need of maintenance. Lately i write JS since it is easier to write complex app in it. But i will consider C#. I just dont want to be taken hostage by microsoft if possible.

I used to use Unity back in 2015 (as well as Unreal but I mained Unity) but a few years later I fully switched to Unreal because I just think Unity versions after 2017 were gradually getting worse over time compared to Unreal which was getting better. Unreal also just feels more game ready tbh as well has having really good built-in multiplayer support and ease of use with it's blueprint system and material editor. It took Unity years to get an equivalent to those features (and they are still inferior tbh) whereas Unreal has had them since UE3 in 2006

I'm learning C# but I don't understand OOP style. It's so difficult.

@GavinLon 12 күн бұрын

My advice if you want to learn OOP is firstly split OOP up into the individual parts, Encapsulation, Inheritance, Polymorphism and Abstraction. Then try to understand each of these concepts at a high level - then try to apply the concepts in your code. Take your time learning these concepts, stay with it and eventually you'll start to grasp the concepts and you'll see the immense benefits of OOP.. Please check out this playlist - kzbin.info/www/bejne/fpTNgJatgrhnadk - to help you along the way :)

@@Nurtastube You can also use other styles using C# but I'll argue that the more you practice applying the OOP style, the more you'll get comfortable using it and reap its benefits. But then again, the beginning of wisdom is knowing yourself (Aristotle) - so you know yourself better than anyone else :) Choose the style that you prefer :) My advice, however, is perhaps don't rule out OOP just yet. :)

In my opinion, they are incomparable. Can you imagine that tools like Docker would be written on C Sharp? It would eat up a huge amount of memory and processor resources and would be slow. C Sharp is designed for pop programming with an emphasis on convenience, and Golang is a high-performance language, whose paradigm is incompatible with OOP, without which C Sharp cannot exist.

Its like comparing hammer and swiss-knife. C#/.NET is more versatile and robust suitable for vast amount of application and domains, whereas Go is more focused language with way more narrow use cases in which it will be most of time more performant then C#, but offering way less language features. Also for smaller projects Go can pull ahead of C# in many cases in terms of performance and ease of use, but with larger scale which will be most of non tool or commercial projects, .NET will scale way better then a Go project in most scenarios

I mainly use c# and Rust, also I'm very familiar with "languages" like Python. Since net9 I must admit the speed difference between rust and c# became so small in most cases, it's not worth the effort. Since the difference between python and rust is sometimes in the tenths of thousands times faster, in c# it's often one-dot-something.

3:11 is "unsafe" code really used in other places than the STD? That's an argument I don't understand. If you really want to deal with pointers, use a low level language.

@GavinLon 24 күн бұрын

Here is a basic example - The advantages of using managed code come with performance costs. For example, when you retrieve an element from an array, let's say its fourth element, the runtime needs to do a check to see if there is a fourth element, and throw an exception if there isn't. With pointers that runtime cost is eliminated. So higher performance is the reason to use pointers (unsafe code). You might only have a few exceptional cases where you want to use unsafe code (for performance reasons) - which means the vast majority of the project will benefit from using managed safe code - and those exceptional circumstances where you need high speed performance, you can implement appropriate unsafe code in those cases. As to what language you use depends on your requirement. It might be better to use a managed language like C# for a project where you only need performance benefits in a few cases, and a cost/benefit analysis reveals that the benefits of using a managed language outweighs the benefit of using a lower level language (which could be more complex, result in longer development time and potentially less robust code).

Why do you say that? :) I find Visual Studio to be the best tool for creating Blazor applications.

@minhgiangho1410 26 күн бұрын

@@GavinLon Visual Studio frequently encounters issues with syntax highlighting for Blazor. It fails to bold tags or recognize components properly, often requiring a restart to resolve. Additionally, the HTML and CSS suggestions are terrible-when opening a <div> tag, it sometimes auto-inserts an unrelated component tag instead. When writing the @if syntax, it arbitrarily inserts a # in the middle, turning it into @#if, which then needs to be manually corrected. These minor yet persistent bugs severely degrade the Blazor coding experience, making it slow and frustrating to work with.

I totally prefer C# because of it's modern syntax and other reasons but I have to choose Java just because I hate windows and unfortunately .NET programming has not fully support for other operating systems. Of course .NET Core can be installed on macOS but we can't fully use essential tools from .NET ecosystem on macOS or even Linux. We don't have Visual Studio and SQL-Server on macOS and Linux. I know it's possible to work with SQL-Server through Docker but it has performance lack. Also we can using SQL-Server Management Studio (SSMS) just on Windows! I don't think Microsoft has a plan to officially bring these products to macOS and Linux (maybe because Microsoft wants to prevent migrating from Windows to another operating systems). In past we had Visual Studio for Mac that was terrible. It was based on Monodevelop IDE that compared to Visual Studio (Windows version) didn't have full features! Finally Microsoft discontinued Visual Studio for Mac and suggest developers to use Visual Studio Code but even vscode doesn't have main Visual Studio dialogs and other necessary tools to work on C# projects. So I disappointed from Microsoft and decide to work with Java language (but in the end I still love C# 😂 )

The CSS caching issue is perhaps a bit dependant on how assets are accessed. e.g. if the rendered url automatically appends something like a ?v=nonce that is , say... an SHA256 value of the file itself... then the request will be unique and cache problems avoided.

Blazor is a piece of shit that not only delivers a subpar experience for the end user from what's already widely used in frontend (React, Angular, Svelte, Vue, etc) by either adding server latency or being slower by being bloated .NET infused web assembly. But wait there's more! It also makes the developer experience worse by requiring Visual Studio for frontend (anybody who tried this knows its not fun), and you end up needing JS anyways and it's so annoying having to do JS Interop in Blazor.

One reason could be because startups tend to hire younger developers and can perhaps pay them less. JavaScript is easier to learn and more JavaScript developers are generally more available.
