Description cod3monk3y 2012-09-21 11:57:20 UTC
Step to Reproduce:
1. Launch MonoDevelop
2. Create a new solution
3. Create a new MonoTouch Library project "Lib"
4. Create a new iPhone Single View Application "App"
5. Create a new MonoTouch Library project "Lib2"
6. Add reference from "App" to "Lib" and "Lib2"
7. Change configuration to Debug|iPhone
8. Build

Actual result:
7. "Lib" not available in active configuration
8. Build failure, Lib.DLL not present.

Expected Result:
7. "Lib" available, since it is a valid

Manually edit the .sln file to add these lines (GUID for Lib is {A9A8...})

{A9A8640A-C650-46AB-A21C-DF3B5D22BAA3}.Debug|iPhone.ActiveCfg = Debug|Any CPU

FWIW, it's possible to work around this by removing the project from the solution and adding it back.

On Behalf of Isaac Eckert | FANUC Robotics

I discovered another problem.  After installing the beta version of MonoDevelop two days ago, some of my MonoTouch projects are no longer recognized as MonoTouch projects.  They still appear in the solution as projects but they no longer have MonoTouch build settings and they are not longer built as part of the iPhoneSimulation configurations.  I did not notice it because I was working with a smaller test application at the time.

I've hit this as well. It only happens when you create a Library Project first, and then add an App Project.

The reason seems to be because Library Projects don't have all of the same configurations that App Projects have.

All projects added after the first project seem to inherit the configurations from the first project, but not the reverse.

So when you add the App Project later and then decide you want to build "iPhone|App Store" (for example), the library project(s) that you added before the App Project don't have that configuration.

Lluis: any idea how to fix this?
Comment 5 Mikayla Hutchinson [MSFT] 2013-02-28 00:28:47 UTC
We probably need some logic so that when a new project or project configuration is added to a solution, we add it to existing solution configurations using heuristic similar to the ones we do when creating new solution configurations: https://bugzilla.xamarin.com/show_bug.cgi?id=6169#c11
Comment 6 Nicolas Raoul 2014-08-29 03:21:16 UTC
Reproduced without MonoTouch. Just a plain C# solution on Monodevelop 4.0.12 on Ubuntu 2014.04
Workaround suggested in comment 1 worked.

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.
