"Assembly not available for Mono/NET 3.5" when trying to build project in MonoDevelop

[ThermalShark]

I am experienced with Unity and C#, and decided to make mods for KSP. I started with copying stock parts and modifying functionality and/or size, and now i decided to make my own plugins.

I downloaded this, and when i tried building one of the projects included (in MonoDevelop), there was an error saying UnityEngine could not be found. I went to the references tab of the project, and there were error icons in the references: Assembly-CSharp, Assembly-CSharp-firstpass, and UnityEngine. The error in all three were: "Assembly not available for Mono / NET 3.5 (in Mono 2.10.2)". I googled about this and it seems nobody had this problem before (not with KSP, and the non-KSP result i found was solved by changing from .NET 3.5 to .NET 4.0, which does not work with Unity.

I have a mac, with MonoDevelop 2.8.2. Any help is appreciated.

Did you reference those assemblies in your project? You need to add a reference to UnityEngine.dll and Assembly-CSharp.dll in (KSPRoot)/KSP_Data/Managed/

I didn't made the projects (see the link), and who made them didn't say anything about that, so i assumed everything would be done already. And it was, but they were made in Windows, with Visual Studio (i had to manually open the solution file in a text editor and change version from 12 to 11, as MonoDevelop would open the file as if it was a text file otherwise. Details here.)

By "KSPRoot" you mean the folder that has gamedata inside? If yes, its not here. I did a search for .dll files inside the folder, and the only results are mod plugins. However, i did the same search on my whole computer, and i got several "UnityEngine.dll" and "Assembly-CSharp.dll" files from my Unity projects. I am going to try that...

It's the main directory KSP is in. On my machine (steam/Win7), it's "C:\Program Files (x86)\Steam\SteamApps\common\Kerbal Space Program." So in my case, the DLLs you need to reference are located at "C:\Program Files (x86)\Steam\SteamApps\common\Kerbal Space Program\KSP_Data\Managed". You should not be looking in GameData

I have just realized all of the files i mentioned earlier are from my BUILT unity projects, from inside the app bundle. It's a mac thing, actually just a folder with stuff inside, stuff that are not meant to be used by end users (but thats not really the case for KSP), and because of that, mac's file searching tool (Spotlight) does not show anything inside app bundles unless you search directly inside them, which is a "feature" i hate. Because those dll files are in my app bundles, they should be in KSP's app bundle too, so i (manually) searched, and they are. So i found out the "KSP_Data" you said is the equivalent to the app bundle in mac. Thanks for the help!

Edit: i started writing this post before you posted your answer. i was looking in the main KSP directory, it was Spotlight behavior that made me not find anything...
