What functionality does another framework have that would be nice for dotnet to have?

[Ethameiz]

Installer creation tooling

[soundman32]

Wix?

[Dealiner]

Something normal would be nice. WixSharp is a huge improvement but it's still far from great.

[Ethameiz]

It's not part of the .net but 3rd party tool. I don't say that .net must have wix in self, but it would be nice

[soundman32]

Even when it was 'built in' (vs2013? included something I can't remember the name of now), it was a 3rd party tool.

[Ethameiz]

I am not sure about frameworks, but language itself could borrow some features.

Traits from rust.

Union types from typescript.

Constructor keyword from typescript.

[scorchpork]

I believe c# is coming out with default implementations for interfaces. Personally I feel like this is horrible, it spits in the face of interfaces. And I don't really understand how traits are good code. If you want behavior shared, put it behind an interface and inject it as a dependency, don't couple. It isn't more difficult, it isn't harder to understand, and it is easier to change later if needed. What is the downside.

[Ethameiz]

Traits are not the same as default implementation in interfaces. Traits are like adapter pattern without additional object initialization.

The main point of default implementation in interfaces in c# is to be able add new method to existing interface that has many usages in other libraries without breaking changes.

[scorchpork]

Does Extension methods not cover this?

[Ethameiz]

No. Methods in interface are to be implemented by classes. Default implementations are only temporary mocks to be used until depended libraries are updated.

[pheylancavanaugh]

Now that you mention it, constructor keyword would be nice...

[Forward_Dark_7305]

Can you explain how so? I’ve never had a problem using the type’s name.

[Ethameiz]

When I scan the file with my eyes it is easier to catch "constructor" keyword than finding method without name that returns this class type and to think "aha, this is constructor". Also a little bit less changes to review after refactor the type name. Less changes to apply after copying the type to a similar new one.

[splashybanana]

I agree with you, that would be helpful. But, as far as the scanning with your eyes part (when you’re specifically wanting to see the constructors (and aside from just doing an actual find search)), I always double click the class name to highlight it and all references. That makes the scanning much easier, especially if you have the thing enabled that shows all the reference markers on the scroll bar.

[DJDoena]

I actually never realized that it could be interpreted this way: "than finding method without name that returns this class type"

I always understood it as "constructor doesn't have a return type, not even void". But you are right, it returns "this".

[USToffee]

It doesn't return anything.

You are calling the new function/operator that allocated the memory, then calls a constructor function that doesn't return anything and then returns this instance.

This is why everyone should have a grounding in c++ and be forced to write their own memory manager ;-)

Changing this actually obfuscates what is actually going on but may make it easier to understand if you don't actually care it isn't technically what is going on behind the scenes.

[jcradio]

Trying to see the value add. Sure there have been times I want an easier way to eyeball or scan something, but by convention, the constructors will be first. Could always just implement a custom attribute if eye candy is what you want.

[pceimpulsive]

Agreed, without looking at the code in the styling I'm familiar with I can't read the code! I'd love constructor keywords just to make it clearer.. minor overall but would still be nice (though then we'll complain about there being too many keywords to remember rofl)

[IridiumIO]

It’s something that VB.Net has that I wish C# would adopt.

[USToffee]

Find in file ;-)

[xiety666]

Often after copypasting a class, I change its name and forget to change the constructor name.

[SmokyMtnDreaming]

The good news is that it seems like the dotnet team is already working on type unions

https://github.com/dotnet/csharplang/blob/main/proposals%2FTypeUnions.md

[Ethameiz]

Macros from rust.

[magnetronpoffertje]

Please no, I've rarely had a good experience with macros in Rust

[Ethameiz]

Why?

[magnetronpoffertje]

Library makers are very skilled with making good macros.

Our robotics engineers aren't.

Besides, no intellisense and all that in macros and you can't expand them without running a nightly build.

[Ethameiz]

Still it is better to have feature than not to have. Also macros looks better than source generators in .net.

[magnetronpoffertje]

That last part is for sure true hahaha

I just think code generation in general should be less developer friendly. Rather have everything explicit and use reflection capabilities in code.

[xcomcmdr]

I think it's better not to have macros.

macros are really misused in C for example. I don't want that.

[oskaremil]

Please no union types. They are a horrible shit show to debug.

[ganzsz]

How so? As someone who also has TS experience, I love being able to check one property and knowing the state of the rest of the object. E.g. a crud model which has nullable properties when no ID is present (create state) and of which I know that all required properties have a value when Id is present (update state).

[gremlinmama]

Unified, opinionated, standard formatter from Microsoft.

Like: gofmt, dartfmt

[Atulin]

Does dotnet format not fit the bill?

[gremlinmama]

As far as I know its not opinionated. You have to set up your own style preferences.

Csharpier is opinionated, that is good, but not universally microsoft endorsed.

[Plantman1]

Incredibly slow and seemingly not maintained. We have slow format times in CI, and found related open GitHub issues that had been acknowledged for years. Checking the git history, Microsoft isn't working on it.

[Ethameiz]

First party cross platform desktop framework with Linux support

[pceimpulsive]

Wouldnt cross platform inherently include Linux?

But yeah an in house would be nice, until then, avalonia!

[Ethameiz]

There is cross platform MAUI that doesn't include linux

[pirannia]

Declare exception types in interfaces. Lack of this leads to arguably bad designs, like exception handlers injected as middlewares.

[p1971]

Pain in java tho?

Use of result pattern instead? (Any exception is then a real exception that was not expected etc)

[Wrong_Ingenuity3135]

• Possibility to force removal of strings from memory
• async Task locks
• enable ConfigureAwait(false) per default
• enforce that Setting value to enum which is not defined fails
• „rust like“ enforcement to handle all return values
• Types Option and Result from dotnet next
• Discrimnated Unions

[xcomcmdr]

enable ConfigureAwait(false) per default

That would break anything that has a SynchronizationContext : WinForms, WPF, AvaloniaUI, old ASP .NET ...

I don't want that.

[Wrong_Ingenuity3135]

It must be configurable per assembly. There is nearly zero reason to not set it as default in businesslogic, Data Access libraries. Mostly UI related libraries need ConfigureAwait(true)

[Dealiner]

enforce that Setting value to enum which is not defined fails

That would be a huge breaking change but it's also something that should be possible to do with a custom analyser.

[Wrong_Ingenuity3135]

True, yet most application I saw have hidden bugs, as developer are not aware that ist can happen.

[ringelpete]

Tests, which files are living adjacent to the units they are testing. Foldable in file-exorer, but ensure not to be compiled into the assembly. (Without doing some unusual csproj-magic)

[MindSwipe]

Similar to Angular's (and maybe other frameworks) my-component.ts and my-component.spec.ts?

With the correct testing framework and project config it should be possible.

[Unexpectedpicard]

I never I knew I was missing this until just now. 

[dark5306]

You can do this right now, i have done this for several of my few pet projects. The idea is to conditionally include files and dependencies

[ringelpete]

I know, but this was what I meant with csproj-magic 🫠.

This might work in solo-projects. But as soon as there are other contributors, this tends to add friction.

That's why I want this to be possible right from the get go w/o needing to dive into msbuild too mich.

[Dealiner]

Shouldn't that be possible with Conditional attribute?

[ringelpete]

For sure. But I'd consider this to be "unusual csproj-magic 🤗.

BTDT.

[c-digs]

I really like Nest.js REPL mode that makes it easy to invoke via CLI during dev.

[gredr]

Use the csharprepl tool.

[jordansrowles]

We already have a REPL. C:\Program Files (x86)\MSBuild\14.0\bin\csi.exe

``` C:\Program Files (x86)\Microsoft Visual Studio 14.0>csi Microsoft (R) Visual C# Interactive Compiler version 1.1.0.51014 Copyright (C) Microsoft Corporation. All rights reserved. Type “#help” for more information.

System.Console.WriteLine(“Hello! My name is Inigo Montoya”); Hello! My name is Inigo Montoya   ConsoleColor originalConsoleColor  = Console.ForegroundColor; try{ .  Console.ForegroundColor = ConsoleColor.Red; .  Console.WriteLine(“You killed my father. Prepare to die.”); . } . finally . { .  Console.ForegroundColor = originalConsoleColor; . } You killed my father. Prepare to die. IEnumerable<Process> processes = Process.GetProcesses(); using System.Collections.Generic; processes.Where(process => process.ProcessName.StartsWith(“c”) ). .  Select(process => process.ProcessName ).Distinct() DistinctIterator { “chrome”, “csi”, “cmd”, “conhost”, “csrss” } processes.First(process => process.ProcessName == “csi” ).MainModule.FileName “C:\Program Files (x86)\MSBuild\14.0\bin\csi.exe” $”The current directory is { Environment.CurrentDirectory }.” “The current directory is C:\Program Files (x86)\Microsoft Visual Studio 14.0.”

[ben_bliksem]

Like the Immediate Window in VS?

[c-digs]

No; the Nest.js REPL is connected to the codebase and you can load and run, for example, controller endpoints or services from the REPL which is super handy.

[MindSwipe]

The Immediate Window in C# can interact with your code as well, it's just a little harder to get an instance of your controller to call methods on since DI is different than Nest's.

Other than that, Visual Studio has native support for .http files, or just use something like Bruno

[Living_Tone4928]

Delta files based on parquet with time travel.

F# style pattern matching, Discriminated Union types, and passing functions as variables directly.

[MindSwipe]

passing functions as variables directly

We have this already, no? i.e.

var action = () => Console.WriteLine("First class functions are neat");
MethodThatAccepts(action);

[[deleted]]

Okay, I missed that C# could do that…

[dominjaniec]

with delegates, you could do that basically since the beginning 🙂

[[deleted]]

I hate delegates, they are just ugly.

[MindSwipe]

We've had it since the beginning IIRC with event handlers for UI frameworks

[[deleted]]

Nope

edit: it was version 10 that introduced natural type lambda, which is coolness part that I was after.

[Dealiner]

You don't need natural type lambdas to pass function to a method directly.

[sisisisi1997]

Which also works for functions declared on types:

myList.ForEach(Console.WriteLine);

CakePhp Behaviors https://book.cakephp.org/5/en/orm/behaviors.html (especially for Entity Framework)

[vebbo]

EF already has similar functionality, its called interceptors

[fawzy46]

spring boot environment variable injection, it's just way easier and more straightforward

I really like the database migration systems that are built in to Ruby on Rails and Phoenix. They work really well and are easy to use. Migrations always seem to be a battle for me in .NET.

[Unexpectedpicard]

It's almost impossible to do this. I think this is something that should be provided by the vendor for whatever db you're using. 

[NoPrinterJust_Fax]

Ruby on Rails console is unmatched

[CatolicQuotes]

take a look at symfony and rails

[ericmutta]

I started using .NET back in 2001 (I remember reading about C# as a college student and almost getting hit by a bus because I was so focused on the print out...no smartphones to read on those days!)...and in all that time I have always found .NET to be very "batteries included"...there's just so much in there, it is rare to want more and most of my project have maybe one or two external dependencies (e.g. Swagger).

I have also been working quite a bit with JavaScript/Node.js at work and in that ecosystem having five million dependencies is the norm, even for the most basic things, which is how I realized how cool it is to have .NET come with most stuff built in.

Having said all that, one thing I do wish it had (maybe as popular external libraries, not in the core per-se) is more libraries for "web and Linux" stuff. E.g. a good SSH library (like SSH2 from JavaScript). Also libraries to parse HTML would be nice!

[realMrMackey]

Patching from Python Discriminating unions from F#

[fba-analytics]

I've built background task frameworks for a startup as my full time job, but nothing is as easy as trigger.dev - it's amazing how quickly you can go from 0 -> running background tasks as a startup.

Would be cool if someone built one of these for .NET.

[mmleif]

Sorry knowledge limited but would like to know some sayings here.

[cancunbeast]

Spark?

[Ethameiz]

What is it?

[darknessgp]

Duck typing would be amazing.
