    I actually disagree very much with your statement of its a waste of everyone's time putting out more linux distro's. Firstly, dotnet or rather at the very least .net core or whatever the latest crossplatform offering is is advertised with installation instructions for at LEAST 7 linux distro's.

    All products that are then compilable by the advertised version of dotnet (e..g .net5) SHOULD then by extension be compilable on the OS's it runs on.... without fail and especially without broken builds checked in.(btw.. when did that become the fashion?)

    Also regarding the issue of checking out code from github and compiling. I always thought that the one branch of code that SHOULD always work (i.e. compile for release etc) was the main/tip/head branch. So imagine me.. using Fedora, goes and checks out msuild. I run "build.sh" ... then I get enough errors to last a lifetime. Now .. perhaps MS handles their projects differently etc etc.. but to me to check out the main branch, hit compile and be faced with errors is a major sin.
    If the code exists for a build to only work on ubuntu, then it should go in the ubuntu branch.
    Why do I made these assumptions? Well.. because its advertised. Cross platform, I see my linux distro is in there .. so why should I not expect something to work? Another point is that there actually arent that many truly unique linux distro's. All more or less conform to a standard. All other distro's are based on the major ones.. so should in theory work.

    Note that my comments aren't said with malicious or hidden intent. Its all something that I'm surprised no one has mentioned.
    I believe a huge part of the success of C# and .Net as a framework is due to the IDE. If you ever used the IDE that came with for example VB6 (Visual Interdev) then you will understand what Im talking about. The part that I think ESPECIALLY stands out with the IDE is the WINFORMS DESIGNER which made RAD actually rather ejoyable.
    Albeit one can claim that it was more or less duplicated from the delphi ide (which was a wonderful ide for RAD in my personal opinion)

    I think MS is missing an opportunity to play a role in somewhat bringing unity to as claimed divided linux community albeit with regards to a small area of programming. They should do the ide on linux.. but do it THEIR way and not try satisfy squabbles between communities. (pref the ide will contain a winforms designer - and not whatever js decides) . If they do it well enough.. people WILL follow. They do have the resources.

    It would have maybe been a bit better to have announced intentions on the main website and not have to dig into various forums around the web to discover that projects are abandoned as I would prefer the news from the horses mouth.

    Lastly.As mentioned , none of my statements are meant in any devious or malicious way. It just seemed a waste to invest 15+ years in mono/monodevelop for someone to abandon it .. doesn't it? ;)

    @marinusmaurice "dotnet or rather at the very least .net core or whatever the latest crossplatform offering is is advertised with installation instructions for at LEAST 7 linux distro's" That only applies to stable releases and I made it clear "Putting too many Linux distributions out there for CI is just a waste of everyone's time".
    @marinusmaurice Your personal opinion on how master/main branch SHOULD work can be honored, but in practice no one is obligated to implement that. Like I said earlier, if you want to live on the cutting edge (compiling the source code) you have a price to pay. Everyone sticking to the stable releases doesn't. Microsoft does have resources, but it has its own rules to allocate them.

    @marinusmaurice I rather not use Delphi as an example of a wonderful IDE (sorry, I wrote Code Beautifier Collection for Delphi, so I knew too much of the dark side). However, I never consider my investment on Delphi/Mono/MonoDevelop in vain, as today I utilize the same knowledge on .NET Core and VSCode.
    Lex Li
    @marinusmaurice About how to get latest information, I think you should consider the following 1) key conferences (Microsoft Build and DotNetConf are mandatory). 2) .NET Blog and its allies https://devblogs.microsoft.com/dotnet/ 3) Community Standup https://dotnet.microsoft.com/live/community-standup Mono/Xamarin have sometimes been covered. There is no longer a single channel to distribute all news for such a huge ecosystem, so we have to get used to that sooner or later.

    Hi all. Is there a way for me to tell mono programs to run via WINE instead of mono? I'm trying to run something that requires d3d11.dll on Linux, and it says that the DLL was not found.
    Chris Marsh
    Hey all, the download page for mono-project and the rpm keys, it seems the rpm keys are no longer hosted properly.
    That returns a 404 now
    Well, a 500 actually

    has anyone gotten dotdevelop to compile? https://github.com/dotdevelop
    Lex Li
    @sysrpl Make sure you are using Ubuntu, https://github.com/dotdevelop/dotdevelop/actions as that's what's covered by CI.

    i am using ubuntu 20.20, have all the requirements, and when i try to build I am still getting this error upon make:
    /home/gigauser/tmp/dotmake/dotdevelop/main/external/fsharpbinding/MonoDevelop.FSharpBinding/MonoDevelop.FSharp.fsproj(29,3): error MSB4019: The imported project "/home/gigauser/.dotnet/sdk/5.0.401/Microsoft/VisualStudio/v16.0/FSharp/Microsoft.FSharp.Targets" was not found. Confirm that the expression in the Import declaration "/home/gigauser/.dotnet/sdk/5.0.401/Microsoft/VisualStudio/v16.0/FSharp/Microsoft.FS30 harp.Targets" is correct, and that the file exists on disk.
    why is make looking for Microsoft/VisualStudio/v16.0? i have NEVER seen any folders like that installed alongside any dotnet core install.
    @sysrpl Have a look at the Wiki page https://github.com/dotdevelop/dotdevelop/wiki/Setting-up-a-Build-Environment and the specific Ubuntu/Debian page. Dotdevelop will build with dotnet 5 installed using the latest versions of mono/msbuild (mono-project preview repos) but note the issues with running/debugging with Net 5. If you are still having problems, try running up a minimal Ubuntu install in VirtualBox, which should certainly work OK.

    Well like everyone you and me are entitled to our opinons.
    My comments regarding checking in code, be it bleeding edge or not, if everyone decides to check in their code (assuming on main branch) without due consideration if the code compiles is really not acceptable.
    It would give everyone permission to check in broken code and let someone else sort it out because "its bleeding edge".
    If one has pride in ones work and consideeration for others especially with it being a public project then consideration NEEDS to be taken and implemented especially with regards to checking in code that others will check out. As I could have mentioned before, I could maybe be behind the times on how the newer devs do things nowadays.
    Also on the note of Delphi, it is or rather was an example of a wonderful IDE .. but I should have mentioned at the time. And Im refering to the way it which GUI dev was done from Delphi/C++ builder 1 days..
    Fortuntely the spirit of how gui dev was done "back then" is currently maintained by the excellent Lazarus project. Florian and the FPC/Lazarus team devs have truly done a magnificent job in maintaining solid tradition in software development.
    They really show how "write once, compile everywhere" SHOULD be experienced.

    anyhow.... mono does seem dead. so does monodevelop.

    FYI, the mono/monodevelop repository has been archived. If you are interested in working on the project, even when archived you can still create a fork of it.
    A better starting point might be the DotDevelop fork https://github.com/dotdevelop/dotdevelop . Thanks to great work by @lytico and @tommih, this can now be built and run (unlike the archived MonoDevelop code) and currently works with projects up to netstandard2.0 and netcoreapp3.1. Work is ongoing to get it running with net5.0 projects, and all contributions and feedback are welcomed!

    pi@raspberrypi:~ $ sudo mono /home/pi/Downloads/welcomePageView.exe
    Cannot open assembly '/home/pi/Downloads/welcomePageView.exe': File does not contain a valid CIL image.
    pi@raspberrypi:~ $

    does anyone know why is this error popping up?

    Lex Li
    @Hits17 You cannot download a random .exe file from somewhere and expect Mono to be able to run on. Mono can only run some .NET Framework based .exe files, and that's what the error message says.
    Hey @lextm . I am trying to run my python program that i have assembled in PyCharm IDE. Do you have any idea how can i run an executable python program on raspberry pi ?

    Hi, I got this error when I open my visual studio on Mac: Service MonoDevelop.Ide.ProjectOperations not initialized. Can anyone help me how to fix it?
    Lex Li
    @Hits17 I don't. Python is not covered by the Mono ecosystem (unless IronPython), so you should go to a Python forum and ask there.
    @YijianLiu1210 VS for Mac no longer has anything to do with MonoDevelop so your only channel to get support is from Microsoft, https://docs.microsoft.com/en-us/visualstudio/mac/report-a-problem?view=vsmac-2019

    @lextm Thanks!

    I'm trying to compile a Unity Project outside of Unity on Ubuntu.
    In Unity everything compiles fine, but when I run
    msbuild Assembly-CSharp-Editor.csproj
    Several Types/Namespaces from cross-assembly are not resolved (CS0246)
    Any Idea how to approach this problems would be welcome
    Hello, I'm try install Monodevelop monoENV to ubuntu18.04LTS, apt install monodevelop , fail reason 504 Gateway Timeout [IP: 443],
    Mono distribute server is down? ping command is ack dest
    hi folks, im attempting to install monodevelop on ubuntu 21.10 impish, can anyone confirm success?
    aah "This project has not been built nor maintained since January 2020 and has been archived"
    @mtj:matrix.org Have a look at the DotDevelop fork ( https://github.com/dotdevelop/dotdevelop ). There are instructions in the Wiki for building on ubuntu and other distros. It's an ongoing project, but can be built and will build and debug various .NET projects. Feedback (and contributions!) are welcomed.

    Hi, I'making a snap from a xamarin gtk project. For that I need msbuild 16 for mono (found that that msbuild version can compile the code for my xamarin app on ubuntu (22.04). BUT right now I must install the full monodevelop to get msbuild 16 for mono. Is it possible to extract only msbuild for mono somewhere ?
    Andres G. Aragoneses
    why would you need the full monodevelop?
    @ekrogh as far as I understand, you just need to install the mono-msbuild or msbuild apt package
    @ekrogh I packaged a xamarin gtk project as a snap too, in case you want to check out how I did it, check my GitHubActions workflows here: https://github.com/nblockchain/geewallet
    (the frontend branch, not master)
    Eigil Krogh Sorensen
    Thanks! I did not know msbuild existed in apt package ! (The reason I want msbuild is that I want to compile my .csproj. I have no makefile - and I don't know if visual studio or vs code can make one. I don't know much about Makefile)
    Hi! is poassible to build modevelop/dotdevelop with msys2/mingw and mono ?

    Hi guys,
    We are having an issue with a Visual Studio for Mac Extension build. Currently we have dependancies to MonoDevelop.Ide and MonoDevelop.Core and we have hardcoded version(17.0) the problem is that for example if Visual Studio for Mac 2022 Preview release new version17.2 our extensions stops working bacause it cannot find the dependancy with the correct version. So is there a way to build an Extension that would work in more than one Visual Studio for Mac 2022 release or we have to release new version of the Extension each time Visual Studio for MAC 2022 releases a new version?

    Excuse me if this question is not for this group, just did not find specific group for VS for Mac.

    Matt Ward
    @NikolayMishev Unfortunately this is not possible. There was an API break in VS Mac 17.3 so your extension would need to indicate it supports 17.3. The app compatibility version was changed from 17.0 to 17.3 due this API break which means extensions that target 17.0 will not be loaded by VS Mac 17.3. The main reason for this is if you are relying on the older API you may cause problems in 17.3 - my log monitor extension caused VS Mac 17.3 to crash, for example. You cannot have the same addin support both 17.0 and 17.3 without rebuilding it. Typically we avoid API breaks and an extension that targets an older VS Mac 17.x version would continue to work on later versions - this was the case for VS Mac 8.10 but we took an API break in 17.3 this time unfortunately.
    Nikolay Mishev
    Thank you a lot @mrward :)
    Hello people,
    I am having a i guess rather simple question though I just can't get it to work. I was trying to setup remote debugging via Soft Debugger and MonoDevelop. I added the "MONODEVELOP_SDB_TEST" variable to 1 or YES (different sourced advice to using different values i tried both though I do not think it make any difference). Unfortunately the "Custom Command Mono Soft Debugger " menu item, that is referenced everywhere i looked, never shows up. Some sources apparantly use MonoDevelop 4.0. Was the feature removed in later versions? I am using MonoDevelop 7.8.4.
    Thank you in advance.
    Jonathan Kirszling
    could anyone tell me when monodevelop will be officially available for the new Ubuntu 22.04 ?
