Assembly-CSharp(unloaded)

Questions & Answers
1

When I open a script in Unity with Visual Studio. The Solution Explorer shows Assembly-CSharp(unloaded). And the Build button I use to build my solution is missing.

Is there any way I can solve this?

I know that this is a relatively old question, but it was the first hit on Google when I tried to find a solution for this problem myself, so I’m answering it anyway.

The following steps worked for me:

  • Close VisualStudio.

  • Close Unity.

  • Make a backup of your project folder.

  • Delete everything in your project folder except for the Assets, Packages, ProjectSettings and UserSettings folders.

  • Reopen your Unity project.

Unity will then generate new versions of everything you just deleted and everything should work as normal again.

This is probably overkill; I’m guessing that deleting only VisualStudio-related stuff will also do the trick, but I didn’t bother to try.
