C# Extension version:

Steps to reproduce

• deinstall VS Community if you have it on your machine
• install Unity 2018.1.f2 without VS Community and without the VS integration.
• install code and and the unity vs code extension.
• there is no way to create the solution and assembly files needed by omnisharp (Assembly-CSharp.csproj, Assembly-CSharp-Editor.csproj, Assembly-CSharp-Editor-firstpass.csproj, Assembly-CSharp-firstpass.csproj, projectname.sln)
• Assets -> Open C# Project does not do anything

Expected behavior

• always up-to-date solution and assembly files

Actual behavior

• no solution and assembly files at all, or only outdated ones (if they were generated before)
• omnisharp will not find any (new) references

How I fixed it dirty

• install VS Community with the unity intergration.
• disable vs code and switch to VS Community in the unity preferences
• click Assets -> Open C# Project to create the solution and assembly files (which only works with VS Community)
• switch back to vs code
• vs code with omnisharp is working again as expected

You have to do this all the time something changed, so this solution is really not practically!

How I fixed it less dirty

First I still need to have visual studio community with the unity plugin installed.

Second, I changed the constructor (line 284) to this:

        static VSCode()
        {
            if (Enabled)
            {
                UpdateUnityPreferences(true);
                
                // disable vs code and reset vs community as the default external editor
                EditorPrefs.SetString("kScriptsDefaultApp", EditorPrefs.GetString("VSCode_PreviousApp"));
                
                // sync will now successfully create or update the solution and project files
                SyncSolution();  
                
                UpdateLaunchFile();

                // UpdateSolution is not needed anymore because it is called over the OnGeneratedCSProjectFiles callback which gets triggered by SyncSolution()
                // UpdateSolution(); 
                
                // reenable vscode
                EditorPrefs.SetString("kScriptsDefaultApp", CodePath);
                
                // Add Update Check
                DateTime targetDate = LastUpdate.AddDays(UpdateTime);
                if (DateTime.Now >= targetDate && AutomaticUpdates)
                {
                    CheckForUpdate();
                }
            }
            
            // Event for when script is reloaded 
            System.AppDomain.CurrentDomain.DomainUnload += System_AppDomain_CurrentDomain_DomainUnload;
        }

Maybe this problem is also the reason for these releated issues:

Not sure where to put it.. I previously open an issue report here as well: dotnet/vscode-csharp#2325

Hm, nobody seems to care.. I am wondering how people are still be able to use unity and vs code properly with this issue.

I did some deeper digging myself. Looks like Unity does not call OnGeneratedCSProjectFiles (vscode.cs line 1298) anymore.

I added the UpdateSolution() call in vscode.cs line 290. Maybe a bit over the top, but at least it's working again:

        static VSCode()
        {
            if (Enabled)
            {
                UpdateUnityPreferences(true);
                UpdateLaunchFile();
                UpdateSolution();
                
                // Add Update Check
                DateTime targetDate = LastUpdate.AddDays(UpdateTime);
                if (DateTime.Now >= targetDate && AutomaticUpdates)
                {
                    CheckForUpdate();
                }
            }
            
            // Event for when script is reloaded 
            System.AppDomain.CurrentDomain.DomainUnload += System_AppDomain_CurrentDomain_DomainUnload;
        }
`

Hrm, I was happy to fast:

The vscode plugin sais "[VSCode] Updating Solution & Project Files" but it actually does nothing.

Looks like this function is broken in Unity2018:

Anybody has an idea?

Did some more digging and testing and found a solution more or less working for me:

First I still need to have visual studio community with the unity plugin installed.

Second, I changed the constructor (line 284 for version 2.7 or line 301 - 328 for version 2.8) to this:

        static VSCode()
        {
            if (Enabled)
            {
                UpdateUnityPreferences(true);
                
                // disable vs code and reset vs community as the default external editor
                EditorPrefs.SetString("kScriptsDefaultApp", EditorPrefs.GetString("VSCode_PreviousApp"));
                
                // sync will now successfully create or update the solution and project files
                SyncSolution();  
                
                UpdateLaunchFile();

                // UpdateSolution is not needed anymore because it is called over the OnGeneratedCSProjectFiles callback which gets triggered by SyncSolution()
                // UpdateSolution(); 
                
                // reenable vscode
                EditorPrefs.SetString("kScriptsDefaultApp", CodePath);
                
                // Add Update Check
                DateTime targetDate = LastUpdate.AddDays(UpdateTime);
                if (DateTime.Now >= targetDate && AutomaticUpdates)
                {
                    CheckForUpdate();
                }
            }
            
            // Event for when script is reloaded 
            System.AppDomain.CurrentDomain.DomainUnload += System_AppDomain_CurrentDomain_DomainUnload;
        }

Basicaly this means, that visual studio community gets selected as the external editor (under Edit -> Unity Preferences -> External Tools -> External Script Editor) for a short time. So when syncing the project, unity uses the community version to create the solution files.

My previous assumption, that OnGeneratedCSProjectFiles() is not called anymore, was wrong. With the above fix, project files are generated again and the callback is triggered afterwards as expected.

Please tell me if that fix helps you too!

@grofie thanks for this. to clarify, this can be tested by replacing the latest version of vscode.cs lines 304 - 328?

but only if visual studio community 2017 is installed? which plugin is that you mention?

[grofie]

Hi @DMlightup,

finally someone joined me in this thread =D

I still had version 2.7 in my project, that's why the line numbers did not match. I just downloaded version 2.8 - and the solution files dont get created automatically again (means the plugin is still broken in version 2.8). Then I replaced the constructor with the code above (you're right, now it's in line to 301 - 328) and it works fine again. Thx for the hint, I will change the line numbers in the comment above.

I think the unity plugin gets installed automatically when you install visual studio over the unity installer.

If you install visual studio separately (like I did), make sure you put the check mark for unity:

To be honest, I am not 100% sure if the plugin is really necessary, but I installed it anyways and did not test the problem without it.

[dmalpica]

Thanks @grofie !

So I still get some assembly warnings but at least I can work without false positives on my code.

For the sake of completeness I'm on Unity 2018.1.0f2 and here is my omnisharp log:

No one cares this big issue

[xahon]

I've tested that latest 2017.x version of unity works with this plugins and vscode create csproj and sln files correctly (https://unity3d.com/get-unity/download/archive?_ga=2.176330017.583502768.1533393667-1270968443.1532679919) (In my case version of unity is 2017.4.8f1, vscode 1.26.0-insider)

[grofie]

Still does not work with 2018.2.3f1.

@xahon Does your 2017.x version of unity still come with monodevelop?

[dmalpica]

I'm on 2018.2.2f1. I noticed some pretty annoying behavior with the prefs window when trying to set VS code as my external tool. It generally works though.
