Sorry to dig up this "ancient" thread, but I was wondering how far you got with this?

I was considering something similar as an idea, though more realistically for the OS4 platform.

I wanted to learn C#, and make a cross platform program.

I started implementing some of the class libraries for .net framework, but it is incomplete.
the basic idea here was to reuse let's say 80%-90% of my program code with out having to change too much.

Porting Mono from Linux won't work well, you need to support native audio, graphics and network API's of AmigaOS, or it's going to be dog slow.

How far I got was "not at all", since I never got any access to a modern Amiga system and as per one of my posts here, I'd decided it wasn't even worth trying to do a 68k port.

I'd actually love to do it at some point, but since I last posted, I've gotten married, become a father (twice over) and been promoted from developer to management (actually this is a reason I'd love to do it if I could, I miss coding!)... so I'd first need to get my hands on a modern Amiga system and then find some time amongst everything else.

On the plus side, mono has grown and grown and become more and more of a mainstream thing. The agreement/partnership between Xamarin and Microsoft adds a lot of legitimacy and should assuage a lot of the "it's a doomed project" naysayers.

Access to 4.1 should be a little easier now. I think you should be able to run OS 4.1 final edition Classic on UAE with a PPC configuration.

May not be that fast, but at least you would have something to work with.

Not sure if it would be feasible, but I wonder if it would be possible to have a code converter that would just replace platform specific code with Amiga friendly code. Then you wouldn't need to run anything extra on the Amiga, the code would just be converted then compiled. I am not much of a fan of extra things running in the background. For instance every time a new Java version comes out then they start updating the stuff that runs on it and then you have things that run with old versions that don't work with the new stuff.

Let's say if it was feasible, some one head done it already.

The "C" and "C++" language is OS dependent, just because "all" Operating Systems are written in this language, and what was written is the difference.

.net is just a windows API, that has its own commands and it object oriented uses "Classes", unlike AmigaOS that where what we call object is just structs, and list nodes.

And even more an issue many of the things that exists in Windows, does not in AmigaOS.

We do not have this Classes this methods, on AmigaOS, that’s originally a Microsoft Windows thing. There is nothing to translate too. [quote]the code would just be converted then compiled.

If we wrote the C++ .net classes, them it is very possible to compile, MS windows .net C++ programs.

Originally, C# was Microsoft Java, it is runtime engine, but instead of Java Classes, it uses .net Classes, the point is that C# takes care of the disposing of things when they are not in use, and C# is safe language, there is no pointers, you can't poke around like you can in C++, You can access things by reference, but so you can in C++ as well, that’s the fundamental difference.

Basically C# allows you to code, without having to worry about finer details. If you tried to compile C# code as C++, you most likely run out of ram fast.

That happens with C++ and C programs as well, when API's change or libraries change things stops working. Unless the programs are statically linked, so libraries are built into the exe file.

It is not "Windows API" although it wraps large parts of native Windows APIs (like Bitmap class what is basically GDI+ repackaged).

As a matter of fact you can although it should be avoided. Typical example is modifying bitmaps directly.

(Struct exist in C# but are no way same with C structs.)

Well it was not designed for Linux, that is what I meant by it.

Basicity you have.

Program (VB or C#) -> RunTime (VB or C#) -> .net API for (C++,C#,VB2008 or newer).

This is actually the Internet of Things version of the .NET core redone using LLVM in place of the Visual Studio runtimes. It is integrated into the latest versions of Mono.

Re:Mono written for Linux
I've run it on my Mac but it looks terrible if you use the .NET native GUI. I'd rather use wxWidgets or something that uses native gadgets.

C and C++ as languages aren't o.s. dependent. Of course, the implementation for a specific o.s. depends on it, but it's obvious: the o.s. has to provide some services to let implement the language and it's standard library.

No, .NET is not based on the Windows API.

Not even "fully" C++, since .NET doesn't support multiple inheritance (from classes) even for the C++/CLR. Only inheritance by interfaces (and a single class) is supported.

The primary language which inspired C# was C++, as its creator stated several years ago.

That's not true. C# has pointers too, and therefore can execute code which is called "unsafe" in the .NET terminology.

That's depends on the application. Also, see above: you can execute unsafe code in C#. Last but not least, you can also compile the whole application in the native binary format at the first execution, optimizing it for the given architecture.
