C# (the default .Net lang) has so much ceremony, boilerplate/scaffolding and IDE dependence (IDE programmers) and OOP overhead that it requires 5x more lines of code than the same app in Python or Go. Every time my interest peaks, I take a look leave with the same feeling that it's a dated/bloated OOP relic and would take all the joy out of programming.

Break the bubble, talk to more C# devs from different kinds of businesses.

Often, you have to make a serious effort, and that goes for all sides.

"talk to more C# devs from different kinds of businesses"

As a PHP dev who's done C#, Java, Perl, CF, VB and more... I'd rarely find any other PHP devs at our local MS and Java user groups. In a few cases, I was the first "PHP developer" some of these people had ever met.

Java/C# tend to be used in larger enterprises, and they tend to be used by people who are... somewhat more 'corporate' in their life. Go to work, do the job, go home - going to local groups/conferences and socializing with non-work tech folks is often not high on their priority list (family, etc may rank higher).

Maybe it's generalizing some, but it's also a lot of my experience over the past 20+ years. I've met some phenom tech/dev folks at pretty much every event I go to, and I meet more "professional" polyglots today than I did 15 years ago, but I found I had to make an effort to find them (beyond just going to my own favorite events).

Earlier quoted context omitted.

VS is very good but I've been using Rider since the start of this year for most work, I found it to be a very strong competitor.

Visual studio crashes and hangs on me multiple times a day. Rider is just solid.

Visual Studio does this for me a lot as well, especially when projects become larger. The number of times the typeahead caused the app to hang is too numerous to count.

Part of me misses .NET, but I've been mostly working with Golang and Node lately. Visual Studio Code is pretty stellar. Maybe someday VS will catch up to VSC. :)

I have been developing in .Net MVC 5 and now the last 6 months in .Net Core 2.1. Core is pretty awesome, I would say the learning curve is pretty high, but I'm very satisfied. Previously, I used Java in school. The .Net stack offers a lot of jobs in enterprise companies, if you are someone that dislikes SV mindset. Also, Visual Studio is an insane IDE. Although, I recently did have some nasty bugs but updates are com…

It's great to see the enterprise world catching up with the tech world

Wait, wait, Visual Studio has been way ahead since forever

If you're interested in .net and the clr, you could replace c# with f#. It's the most practical functional language that I've tried. Great for domain modeling and it can used in C# projects. I also think that c# is too verbose so what I normally do: asp.net core mvc for routing, templating, authentication / authorization, data access etc and then reference an f# project that contains the domain logic. The best of bot…

As a complete newbie to .net, I’ve tinkered around with f# for a web app and quickly got frustrated. I like the sound of your approach. Do you have any links / resources for the best way to get started with your approach?

I fail to see what the point of trying to use VS Code for .NET development would be. I suppose if you like tying one hand behind your back and making things more difficult for yourself for some reason. Or maybe you like cobbling together a rickety pile of plugins.

If cost is a concern, there's Rider or even MonoDevelop.

List of performance improvements is mind-boggling: https://devblogs.microsoft.com/dotnet/performance-improvemen... How could a mature standard library / frameworks have so much performance gains to be had?

I believe most of these are from Span which allows doing a lot of operations (e.g. substring) without allocating a new object.

The "core" library was designed for portability and it's not as old as the .NET used for Windows desktop development, which is very mature and very performant.

.NET Core is faster than .NET Framework

> Nullable enables you to directly target the flaws in code that lead to NullReferenceException. The lowest layer of the framework libraries has been annotated, so that you know when to expect null. I hope Java gets this one day.. would be a cool feature

You can try checkerframework [1], which uses annotations to perform extra typechecking at compile time, including nullable/not-nullable checks. Works properly altough it has a few issues: the biggest is that support is still stuck at java 8, and the framework is sometimes not smart enough to see that you already checked if a nullable field is null or not and you can safely use it.

The only way to get C# 8 is to move to .NET Core, I can't really avoid this anymore. And for me it means moving to ASP.NET Core... Anyone recently migrated projects from ASP.NET MVC to ASP.NET Core? I hope there is a gradual way, like this: https://www.hackernoon.com/how-to-migrate-project-from-aspne...

I'm not convinced ASPNETCore 3.0 is ready to be used in anger yet. Perhaps this thread from a couple weeks ago is not representative, but I've seen other similar feedback
