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.

Agree with your complaint on async. And on asp.net, async doesn't disrupt that much the workflow (but creates the possibility for deadlocks). But if you are dealing with a UI and make a method async, then suddenly you have a ton more problems to deal with, like what happen if the user changes the state while you are waiting for an async call. That increases a lot the complexity of the code. Which is why I am lukewarm about their approach of mandating async for new features.

Authentication is in the request pipeline, so it makes sense that it's async if you're talking to some sort of storage engine. We're using the async APIs to pull user/client app information from our database. Why would we want that to be synchronous?

For simplicity? Just like how js get async await thing eventually.

So you want to pause the thread and keep it from processing other requests for simplicity?

With Linux support AOT compliation and other goodies I wonder how many people will prefer writing backends in .NET over Java.

I think that Java ecosystem is more diverse. There are multiple JDK implementations. There are a lot of OpenJDK builds from different vendors, including paid support options. There is an extremely mature library and tooling ecosystem. While I don't think that JVM is superior to .NET VM, it's not inferior either. .NET supports value types while JVM support some very advanced garbage collectors. And, of course, JVM dev…

Kotlin is getting a pretty solid push as a server-side language too. Everyone I have talked to that uses it is a proponent.

> .NET 6.0 will use the same approach, with net6.0, and will add net6.0-ios and net6.0-android Huge endeavor and launch! Looks like mobile app development will be the same with Xamarin

Mobile development in C# is just dead. Flutter got all the momentum.

Google will move on and then all of the developers who hinged their platforms on it will need somewhere to go to.

You'd want your config injected so that you can swap out configs for test harnesses for continuous integration and deployment. It's one of the mainstays of making your software deployable by automation.

You can do that just with different config files or env vars too. No need to complicate code for stuff that can be done easily differently as well.

Does anybody knows if .NET 5.0 will be included in Windows as a Windows Update as the .NET Framework ?

It won't be. .NET Framework is an embedded component of Windows. .NET Core is something apps have to package along with them. (Due to this, .NET Core apps are larger than .NET Framework apps, but tend to have less compatibility issues in theory, since they bring everything they need with them.)

I used to be an asp.net developer before. I appreciated the idea behind asp.net during its early years - making websites fast and with templating (or scaffolding). Later realized that it is bloat.

Then asp.net mvc happened, a whole new paradigm shift. But then I disliked the idea of stuff getting inherited from somewhere. *.cshtml files and all. Soon I realized what the ide is actually doing behind the scenes. For e.g. the cshtml files are compiled and there is an intermediate binary format I guess. (Don't remember well).

This is why I came to like something like express. Guaranteed there is no type safety. (JavaScript is a dynamic language). But I enjoyed the simplicity of it. Ever since I have moved away from the .net platform.

I know this code generation and intermediate binary forms are necessary. But at times I was surprised by it. You find the similar stuff for other stuff you write for e.g winforms, windows presentation apps, etc. I realize there is no other alternative way for such platforms. But I generally disliked the idea that my editor does a lot of stuff behind the scenes. This makes me too dependent on the editor. For e.g. try making winforms app with just notepad. It's not impossible; just very cumbersome.

I have respect for .net. In fact I do write console programs time to time. But I wish stuff was as simple as having a plain editor and getting started.

the highlights are great. 2 lowlights: - HttpClient/WebRequest ReadWriteTimeout is silently ignored which can result in infinitely hung sockets when doing synchronous network i/o - System.Speech is unsupported

Refusing to support System.Speech is why my project will remain locked to .NET Framework. Apparently the Microsoft Speech team is part of Azure now, and has decided nobody needs local speech synthesis that doesn't require a subscription to a cloud service.

You can do that just with different config files or env vars too. No need to complicate code for stuff that can be done easily differently as well.

And then you realize that it's 2020 and you don't want configuration files, you want environment variables. Or, now that you've hardstuck yourself on environment variables and built all this stuff around them to set and re-set them properly between tests (now running either in multi-process, which good luck in most environments, or are just running in serial), you're using k8s and the voluming of secrets rather than exposing them as environment variables requires refactoring any code, both operational and testing, that touches them.

"But wait," you say. "I'll just pass in the thing that provides that data"--and you just reinvented DI, albeit likely poorly.

DI is the removal of complication when it is done correctly. (I have no opinion on whether ASP.NET Core does it correctly.)

>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…

Do you type every line typically? If you use Rider or VS pretty much every one of those lines can be auto generated with autocomplete. Also, this can easily be worked around. Just create a Singleton which has the settings injected into it. I prefer the testability of the injected version but if you'd rather access a static global it is very easy to do.
