Description Alan McGovern 2012-03-22 11:28:29 UTC
1) Create a project
2) Add MonoMac (provided by monodevelop) as a reference
3) Ensure "Local Copy" is enabled
4) Build the project

Result: MonoMac.dll is not copied locally.

This is specific to MD's "package" references. For some reason, MD assumes that all assemblies from "packages" are GAC assemblies and should not be copied locally. Whereas VS/MSBuild, when copying assemblies from assembly folders (analogous to MD's packages), actually checks whether the assemblies are in the GAC. That isn't ideal either, since it means that the build behaviour depends on the GAC, but at least it's more likely to do what the user desires.

MD's behaviour doesn't usually cause problems because most package assemblies are in the GAC, however, note that the MonoMac addin and ASP.NET MVC project type addins have to specifically work around this behaviour in a couple of cases:
https://github.com/mono/monodevelop/blob/master/extras/MonoDevelop.MonoMac/MonoDevelop.MonoMac/MonoMacProject.cs#L177

Probably the best solution is to mimic VS. We might get this automatically when we move to xbuild...
Comment 2 Jo Shields 2012-06-15 16:15:24 UTC
So apparently this is a big problem for me too. I'm trying to fix up the MonoGame templates so they actually work, and they don't - because MD refuses to copy the non-GAC MonoGame.Framework.Linux assembly to the output folder. Build works, run fails. Clusterfuck.

Non-GAC assemblies are not uncommon, and it's not unreasonable to expect them to be used by users. Something like Cecil, for example, breaks ABI all the time. Telling developers "do a file reference instead, it's just as good" is incredibly user hostile.

For now I'll look at stealing that MonoMac hack - but it's a hack, and MonoDevelop should do better.

I just tried this in f-spot using xbuild and it appears to be broken in xbuild as well.
Comment 4 Marcos Cobeña Morián 2013-09-25 06:38:27 UTC
Updating our templates (Wave Engine) from MonoDevelop 3 to Xamarin Studio we've also encountered the same issue, could you please let us know any estimation or similar about when this could be worked out?

Thanks in advance!
Comment 5 Mikayla Hutchinson [MSFT] 2013-09-25 18:05:07 UTC
No ETA on fixing this, sorry.
Comment 6 Marcos Cobeña Morián 2013-09-26 02:19:23 UTC
OK, no problem, we'are also working with the workaround.

Thanks Michael.

Thanks so much for taking the time to submit this report! I attempted to reproduce this issue based on the bug description with the latest Visual Studio 2017 for Mac Preview version 7.2, and I was unable to hit the problem. If this issue is still occurring for you, please reopen this report and attach a reproduction, ideally starting with a new template project and then adding just the code necessary to demonstrate the issue.
