MobileBlazorBindings VS .NET Runtime

It's difficult to imagine. But if the rumour has any merit, perhaps it simply means that there will be a push to consolidate on some blazor tech using stuff like https://github.com/dotnet/MobileBlazorBindings

There's Blazor Mobile Bindings but it's essentially experimental at the moment and isn't exactly active. From playing around with it though, it is pretty neat as you get the Blazor programming model but with native controls.

The benefit at least with the approach instead of embedding Avalonia inside Maui is you could potentially use non xaml frameworks for ui as long as they support Maui as a target. Stuff like Comet or Blazor mobile bindings would be possible aside from xaml. Especially if they're coming from Blazor web or code based ui frameworks like flutter which makes it appealing.

This is one reason I'd really love for them to push through on making alternatives to XAML like Blazor mobile bindings.

I'd say Blazor mobile bindings is also pretty interesting imo, unlike Hybrid it doesn't use Html and uses MAUI controls directly but still keeps the Blazor programming style and still uses razor to tie in C# and components.

Oleksandr has been contributing to the official experiment project, and singlehandedly updated it to support .NET MAUI. He even now has documentation on his fork.

I really hope Blazor Mobile Bindings takes off imo. I still care for native controls and if Mobile bindings does become a valid target, then you'll have an alternative to XAML when writing native components but using Razor syntax (which imo is less verbose). It'll be like how React does it (which is still pretty popular) where you have React web and also React Native which uses the platform's native controls underneath. Both aren't exactly the same but since the framework is similar (React, Blazor) it should be easy to swap between the two.

Yeah I really hope they'll productize Blazor Mobile Bindings (currently experimental), it's essentially using Xaml controls via Razor as the markup format instead and can use C# expressions (so less need for converters).

For example, in Android there's this file: https://github.com/dotnet/MobileBlazorBindings/blob/main/templates/BlazorHybrid-app/NewApp.Android/wwwroot/index.html

It means you can use Blazor's syntax to write MAUI apps, as an alternative to XML-like XAML syntax.

.NET has explicit tailcalls - they are heavily used by and were made for F#.

The description indicates it is not production ready, and is archived at the same time.

If you pull all stops in each respective language, C# will always end up winning at parsing text as it offers C structs, pointers, zero-cost interop, Rust-style struct generics, cross-platform SIMD API and simply has better compiler. You can win back some performance in Go by writing hot parts in Go's ASM dialect at much greater effort for a specific platform.

For example, Go has to resort to this https://github.com/golang/go/blob/4ed358b57efdad9ed710be7f4f... in order to efficiently scan memory, while in C# you write the following once and it compiles to all supported ISAs with their respective SIMD instructions for a given vector width: https://github.com/dotnet/runtime/blob/56e67a7aacb8a644cc6b8... (there is a lot of code because C# covers much wider range of scenarios and does not accept sacrificing performance in odd lengths and edge cases, which Go does).

Another example is computing CRC32: you have to write ASM for Go https://github.com/golang/go/blob/4ed358b57efdad9ed710be7f4f..., in C# you simply write standard vectorized routine once https://github.com/dotnet/runtime/blob/56e67a7aacb8a644cc6b8... (its codegen is competitive with hand-intrinsified C++ code).

There is a lot more of this. Performance and low-level primitives to achieve it have been an area of focus of .NET for a long time, so it is disheartening to see one tenth of effort in Go to receive so much spotlight.

It's an interesting "time is a circle" problem given that a century only has 100 years and then we loop around again. 2-digit years is convenient for people in many situations but they are very lossy, and horrible for machines.

It reminds me of this breaking change to .Net from last year.[1][2] Maybe AA just needs to update .Net which would pad them out until the 2050's when someone born in the 1950s would be having...exactly the same problem in the article. (It is configurable now so you could just keep pushing it each decade, until it wraps again).

Or they could use 4-digit years.

Yes, that is true. I'm not sure about JVM implementation details but the reason the comment says "virtual and interface" calls is to outline the difference. Virtual calls in .NET are sufficiently close[0] to virtual calls in C++. Interface calls, however, are coded differently[1].

Also you are correct - virtual calls are not terribly expensive, but they encroach on ever limited* CPU resources like indirect jump and load predictors and, as noted in parent comments, block inlining, which is highly undesirable for small and frequently called methods, particularly when they are in a loop.

* through great effort of our industry to take back whatever performance wins each generation brings with even more abstractions that fail to improve our productivity

If you care about portable SIMD and performance, you may want to save yourself trouble and skip to C# instead, it also has an extensive guide to using it: https://github.com/dotnet/runtime/blob/69110bfdcf5590db1d32c...

CoreLib and many new libraries are using it heavily to match performance of manually intensified C++ code.

We might not be that far away already. There is this issue[1] on Github, where Microsoft and the community discuss some significant changes.

There is still a lot of questions unanswered, but initial tests look promising.
