What steps to make JULIAdotNET work with .Net Framework ?

[BambOoxX]

I am trying to adapt this into one of my existing .Net Framework projects, but it fails on the UnmanagedCallersOnly.
I don't know how to modify the implementation in order to no use that, would you have an idea ?

[HyperSphereStudio]

Oops I forgot to push the latest version which added directives that included it if and only if the unmangaedcallersattribute existed.

[HyperSphereStudio]

Oh interesting I did not know that. I will lower the language to 7.6

[BambOoxX]

FYI If you follow this link https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-version-history#c-version-73, you'll see that from c# 8.0 the language targets specifically net core. I assume that implicitly that means that net framework is not supported with newer versions

[HyperSphereStudio]

I was able to lower the language to 7.3 but unfortunately 3.0.0 broke a lot of the internals of the code during testing. I will iron out the bugs but it will take some time (college starting back up :/ ).

[HyperSphereStudio]

One feature that will be really nice in 3.0.0 is automatic object ownership though! Previously you had to use sharppin / free to manually pin objects. The newest version will behind the scenes handle this for you

Oooooh that's a nice addition indeed, well done!

btw , but generally , I have have had to move everything to net6.. even if WPF and only windows only and DirectX interop on some of it. I build a game with CCScipt, AvalonEdit, level editor WPF, C# and MONOgame wiht dynamics code in it. embedded in the wpf.. struggling for weeks but getting close. because of legacy net4.8 modules, n the level editor. Microsfolt Code Analysis is a preparser that might support other languages. CSScript is c# only. .Net Silk attempts to generate wrappers for all graphics lib. all are getting HEAVY daily flux from 100s of people, some sponsored, some on MSFT payroll, and some on JetBrains, its amazing they work together under Net foundation with only the slightest conflict of interest over tooling. But MSFT is selling cloud services mostly now ... as for moving to net6 , new core. its just impossible not to.. the industry is moving that way and you cant link.48 to net6 libs. i have legacy code but windows-upgrade helped a little.. i had to make all new projects and use the new simpler SDK projects.. i strongly suggest you ditch 4.8 completely, its dead.. and netstandard 2.0 isnt realy working.. i had to upgrade from netstandard 2 to net6 cores and my physics libraries speed up 20% . im using Monogame, scripting , plugins, depubbign and interested in scientific visualization... Net 6 is completely open source , there is an amazing Silk. Net project wth tons of MFST stafff oon it. I guess there are tooling squabbles but JetBrains is sponsoring as well.. Julia is a very interesting language for science but I use C# for its incredible performance adn deployability.. I think julia if strongly typed has a strong future in actual production code but, for game engines adn perfromance scientfic simulation, for targeting many platforms wth one codebase, its looks like .net foundation is better broad support.. MSFT isnt caring about locking anyone to any platform they make their revenue on cloud services now. merely updating form Monogame 3.8 to 3.81 has set me back 3 weeks.. i just want clean simple project files that target anything.. Some of the science code i i see now is Julia, like Gabriel Weymouth's CFD code lilypad and frankly i thnk that its the best syntax. But i need to deploy production code that runs physics at 4000 fps and draws at least 60hz. simply rebuilding my physics engine to net6 gave me 40% frame rate boost.. its worth it. I dont know how julia works.. how it deploys but compatibility with .net foundation somehow would be great contribution to science. Right now most simulationcode is openGL, cuda or stuff that only one person can compile. In dotnet tooling you clone build and it works. ( or should) and on almost any device with multiple tools, Resharpers, MS Code, Dev Studio, running on ARM, deploying on phones, MS Code etc... sorry dont have time make this clear and concise m swamped with unexpectged work but it has to go forward even now when its in flux... it will stabilize after this major transition i hope

I'm not sure if I understood your point fully, but just to rephrase the .NET Framework issue in my case : we build our soft partially on top of a commercial soft that, at the moment, is locked on 4.7.2. I would like for the company responsible for that soft to upgrade, but it's not planned at the moment. Otherwise, I'd be really happy to upgrade myself, it would surely save us from a lot of trouble.

[damian-666]

you might try MSFTs upgrade-assistant... tool, if helped me in my case by adding some windows compability stuf to legacy modules that need net48 to work or are no longer maintained.. now m using net6 on everything i have source to or open source thats been maintaned, but for those dlls, and it brings in the old net 4.8 stuff somehow, its working on windows at least. probably worth a try...

[BambOoxX]

Thanks I'll have a look at that

@damian-666, just tested the migration tool on another project. It's not a one-click business, but it's fair to say it's working just fine. Thanks for the tip.

[damian-666]

yea , glad i might have helped someone but dont get too optimistic unless your actual project u need to ship works and deploys . its depends on yhour roadmap i guess.. it was like press 1, over and over and ten min later it added tons of stuff and worked. I had some good luck, at first ..BUT... but in case its relevant to your similar struggle .i strripped everything the assistnat added.. because now Im stuck because someone dropped Netstandard 2 support in one of my components i updated, monogame, to mg 3.8..1 i probably should not have adopted it so soon.. the upside is that it cana use ssystem numerics persistent Vector2 .using SIMD.. which i really want. and Netstandard 2 doesnt have it.... so i moving ahead despite the cost. so then i had to i bite the bullet rebuild all my projects from stratch templates, moving ato net6 libs, net 6 core..... the files are soooo simple now..i stripped the stuff upgrade assisten added and dont see regression YET.. . its all ANYCPU... also , for now.. then referenced the old l closed sourch icensed components docking wpf dlls on net48 and most of it works. and even w/o compatibility sutff.u .but , because of nuances other things are broken, Im so stuck i am looking at Silk.net , other UI frameworks, as well for fresh ideas. but this SIlk is very new.but very clever methodology they are using to do unification of all the zillion device for scientific visualization. anwyas glad if that new MSFT script actually helps in your case.. they update that tool often.. The new project . net project format and tooling is much simpler, but well, completely different... msbuild has alot of new things in config and json files one mght need ot read about.. It would be great if julia and silk cna work together.. because i do simulations and physics games with fluids and rigid bodies . c# math doesnt look like math in the papers and its rare to find research code that builds and links. . and would love to have some solvers that look like math from the research papers AND shippable / scritpable high performance code like net 6 is just blazing fast... and im running on about 4 differnet targets now.. android and pc from shared code, and with shaders... Also if weird things happen when u revert changes and using vs 2022 , CLEANyour cache files.. those would be are in USER and in TEmp ..folers on ur machine. fi using. Vs 2022 , search by date and clean anything thats went things went south after you revert something... long read but i spend 4 weeks on this.. so hope something saves u time.

Well, thanks for all this info. I have to confess my use case requires much less interaction between Julia and dotnet and also much less 3d vizualization. Nevertheless I fully understand you troubles, good luck with all this!
