✅ native code in .net

got a question about the native code in the dotnet universe.

why do we need it?
is there a way that we can remove the native code so that we can have better support on linux?

Doesn't .NET already notify you when certain functions and such are only available on a specific OS?
Afaik System.Drawing(.Common) has a warning telling you it's only available on Windows

There shouldn't be any big issues running C#/.NET on a Linux system, I do it all the time

why would we need native code in the first place

The Fog from Human Resources•5/5/24, 11:11 AM

Why would we not

charlieOP•5/5/24, 11:12 AM

because then crtain classes don't exist

for different platforms

Native code depends on your OS features
If for example System.Drawing is only available on Windows it might be, because the system libraries support it

In that case you should blame Linux and not dotnet

In most cases dotnet runs on any OS perfectly fine

are u refering to something specific like WPF?

charlieOP•5/5/24, 11:15 AM

why blame linux when you can just implement c calls or whatver and just make a pull request

leowest•5/5/24, 11:16 AM

or some framework that is windows only?

leowest•5/5/24, 11:16 AM

because if u are then the answer is that is not that simple

leowest•5/5/24, 11:17 AM

using WPF as an example its so tied coupled with DirectX that you would need to completely rewrite it, in order to make it xplatform compatible

Lleowest are u refering to something specific like WPF?

so i'm learning the Cosmos framework https://github.com/CosmosOS/Cosmos . and i'm reading the discord and wondering why we have to make methods directly in C# that do the same thing as native code but can be packaged for other systems where the native code doesnt exist

Isn't MAUI already compatible with Linux etc if GUI is the issue

The Fog from Human Resources•5/5/24, 11:18 AM

Pluh

isn't there a wy that we can just allow non native cod in a sandbox?

can u provide some examples? because there are a lot of things that in order to access it you have to access the native code of the specific OS, as c# can't directly access it.

leowest•5/5/24, 11:20 AM

by either wrapping around a library or something

leowest•5/5/24, 11:21 AM

there is also the standardization problem between all distros

so, plugs replace native code by writing them in C#.
currently most of the community has to work around System.Void and it's related classes because it's a sort of "native" class.

charlieOP•5/5/24, 11:22 AM

being able to work with something that would allow us to use them somewhere else would be nice like Cosmos. because i think we spend more time writing asm like code using X# or actual ASM code to get around this which brings up the point of even doing it in C# in the first place

leowest•5/5/24, 11:23 AM

Plugs reads to me as the same of what LibraryImport and DllImport does

here is what i can find related to plugs https://github.com/CosmosOS/Cosmos/tree/master/source/Cosmos.System2_Plugs/System
