The project *projectname*.Editor cannot be added to the solution about assetbundles-browser

@alffanclub Just FYI I've figured out what the actual problem was - it was just that I was running a slightly older version of Visual Studio which doesn't support asmdefs. Once I updated Visual Studio to the latest version everything is fine. Confirmed this with someone else in the forums mentioning the same thing

I was able to fix this error message on my project by opening ProjectName.sln in notepad and deleting the duplicate entries at the top.

Thanks for all the details. Yeah, asmdef files work in mysterious ways that I also don't fully understand :)

I'll test a few different versions of 17.3. If it's isolated to 0f3, we may be ok, but if it's broken for all of 17.3, I may need to diverge the browser development. Hmm.

Well, thanks again. I'm glad you've got a good workaround, and hopefully I can land on a more permanent fix that doesn't cause people too much grief.

None of these worked. After updating VS to the latest version I had to delete all the .csproj files and the .sln from the project, then it rebuilt and worked.

@arvz what version of Unity are you using? We added .asmdef files to the project, but I believe there may be some versions of Unity that have issues creating the VS projects when those are present. As a workaround for now, you can probably delete "Editor/com.unity.assetbundlebrowser.Editor.asmdef" and "Tests/Editor/com.unity.assetbundlebrowser.EditorTests.asmdef".
Please let me know which version you're running, and if deleting the asmdef's fixed it.

Thanks for letting us know about this issue,
Bill

@alffanclub I'm using Unity 2017.3.0f3, If I delete the 2 .asmdef files, this happens when I open the browser:

But it's an easy enough fix: Deleting Line 5 of AssetBundleBrowserMain.cs:

[assembly: System.Runtime.CompilerServices.InternalsVisibleToAttribute("com.unity.assetbundlebrowser.EditorTests")]

Makes it work properly now.

But I am noticing something strange. After I deleted that line I opened the browser - which is working now - but then I added the line back, recompiled and tried the browser again, and it's still working. I even tried deleting and re-adding the folder back into the project and the browser still works even without having touched that line. I guess .asmdef files work in mysterious ways I don't quite understand

Hello, I have approximately the same error when opening a CSharp file from Unity into VS

The Unity version is 2018.2 Beta 5
I don't know what to do, IntelliSense doesn't work as it should

[GuismoW]

HI. I reinstalled completely updated Visual Studio, and it worked

Hey ! I had the same issue and updated my Visual Studio Community to the newest version and it worked.

Unity 2018.2 had very similar issue right after upgrading from 2018.1

Solved: Updated Visual Studio 2017 community to V.15.7.6 (previously had V.15.3.x). Thanks for the tips guys!

That's why I don't like upgrades.... (aren't those to have fewer bugs, not more??)
