So, on the plus side with the new .net, I recently made a .net core web app on Linux, and generally it's been pretty easy. I'm also impressed at just how fast asp.net core is compared to asp.net, the time it takes to open your site in debug mode has dropped dramatically, from what used to be 1/2 minute in asp.net to a few seconds in .net core. On the bad side? Mainly the asp.net core team and their push for Dependenc…

Can't you just ignore the built in configuration and roll your own (probably there's a dotenv library?). That said, I've also personally moved away from C# despite really likeing the lanaguage due to a lacking ecosystem. I'd recommend both node with TypeScript and Rust for backend web development in a statically typed langauge.

We started to use F# with Elm and it works very well. Statically typed all the way.

>and you're in for an even bigger nightmare if you want to separate business logic and web code into two projects (which is a pretty common design). I've given up with the config DI and just assign them all to static variables. So you have static variable in web project and then add reference to web project to obtain that config? Do I get that right? I never felt like config DI was a problem once you did all the stuf…

To me it's just so pointless, here's an example: using Microsoft.Extensions.Configuration; //extra line using Microsoft.Extensions.Options; //extra line public class AdminController : Controller { IOptions settings; //extra line public AdminController(IOptions settings) //extra code { this.settings = settings; //extra line } public void RandomMethod() { var a = settings.Value.FinallyMySetting; // 5 extra lines to acc…

In their defence, there is a default builder that would save you maybe 3-4 lines there, but I do generally agree with your point.

It is something that annoys me about .NET in general there is just decades of over-engineering cruft and once these practices emerge its difficult to get people to stop doing them. The problem only gets worse as time passes.

I found Go to be a really nice replacement for C#. It has the static typing and garbage collection, but you also get a self-contained binary executing without the requirement of an external runtime environment. I also discovered that I don't miss classes at all.

I have migrated from C# to Node.js, my code is now 20x times shorter (from 800 files to 40 files), simpler to read and maintain, there is 100x more packages available on NPM compared to nuget. Performance is stellar, even better than in C# for my use case (Mega tons of concurrent queries executed in 1-5ms avg) And also I don't have to fight against the language to do what I want to do ... No classes, no types, no con…

>20x times shorter

that's giant, but I don't think that "just" language / environment difference makes this huge difference

As someone who uses .NET daily, but loves Clojure and other functional programming paradigms - Records seem like a very compelling feature. Immutable data structures without any hassle to set up. Simply write “record” where you would normally write “class” and boom, you are working with immutable objects. This is one step closer to one the best features of Clojure IMO -everything is immutable. Additionally, there see…

Record looks like scala case classes. I miss them; they save a lot of mucking about (like, loads). Immutability is an extra, it's the brevity it brings.

They've done absolutely nothing to make migrating from MVC 5 any easier, while proclaiming that this somehow merges .Net Framework and .Net Core. Going from MVC 5 to .Net 5.0 MVC is a complete re-write of the web layer from an empty project upon up (even according t…

> From the previous version of .Net Core only. Which is already three major versions ahead off classic .net. You’re literally complaining about making upgrades past four major releases not being drop-in compatible. Can you show any other stack which has made such strides to modernise and maintain better compatibility?

No, I'm literally complaining about the misleading messaging surrounding .Net 5.0 "merging" .Net Framework and .Net Core. My post was very clear on that. Like this quote from the linked article:

> .NET 5.0 is the first release in our .NET unification journey. We built .NET 5.0 to enable a much larger group of developers to migrate their .NET Framework code and apps to .NET 5.0.

is this an in-place update to the netcore3.1 runtime or does it install side by side for net5.0? just want to know what kind of risk it is to install. i got bit by the netfx48 in place update.

Side-by-side.

It’s effectively .Net Core 4.0, but they removed the “core” and versioned it 5.0 to make it more obvious that it supersedes and obsoletes .Net Framework 4.8 which lots of organizations are still clinging to.

You probably know, but F# exists if you want a functional language in the .NET ecosystem. Granted, you end up dealing with a bunch of OOP libraries still since .NET is very C#-centered, but the language is pretty good and the integration is painless.

If I wrote a F# codebase at a lot of companies I would find myself swiftly booted out the door.

People who think this is actually cross-platform need to consider these points: * Debian can't package F# because it is built using MSBuild, and MSBuild is built using MSBuild. How can it be Microsoft doesn't have the resources to get it into a major distribution? * Microsoft won't commit to maintaining any cross-platform GUI libraries. You will be relying on some random community project. Compare this with e.g. Pyth…

Isn't that MAUI?

Does Asp.NET identity still use a Guid for primary key? I remember it being hell trying to convert to int a few years ago which left a sour taste.

I use Rider now, VS got to the point of being so slow that frequently I'd have to wait 0.5 seconds for each character I was typing to appear. The performance is utterly, utterly terrible. Yet, all I see from the VS team on Twitter is "look at this new useless feature we've added", when all I needed was for the code I'm typing to appear. God help you if you ever wanted to rename a symbol, it was Schrodinger's rename,…

I'm using newest VS with Roslynator (instead of Resharper) and it doesn't feel slow once it "warms-up"

I do have NVMe M2 Disk if that matters
