Question by Shinobi_Lord · Aug 12, 2018 at 05:53 PM · namespace

Unity-related namespaces not being detected.

Upon opening up a project, I am met with the same Visual Studio error/warning messages 4 times in a row :

The project cannot be added to the solution because a project with the same project filename already exists in the solution.

While initially working on a project, namespaces like 'using UnityEngine' or 'using UnityEngine.SceneManagement' work just fine, but again, once I save/exit, and then re-open the project I encounter these errors.

  • While typing this question, MonoDevelop has opened up on its own. (I do not use MonoDevelop and haven't opened it in years.) Would uninstalling/disabling MonoDevelop help this problem? (Even if it does, I am wondering how to solve the underlying issue.)

Thank you for any of your time and help.

Hi everyone.

After some more research, I found a post on github : https://github.com/Unity-Technologies/AssetBundles-Browser/issues/66 regarding my problem. Although I still cannot explain the origin of my problem, the solution was to simply update my VS2017.

According to the post, the problem had something to do with 'asmdef' not being supported with my version of VS2017.

For clarity, my Unity namespaces now complete/are "detected", and no more interaction with MonoDevelop starting up on its own.

Thank you all for your time and help.
