Incorrectly reporting errors in unity project

Environment data

dotnet --info output:

.NET Command Line Tools (1.0.4)

Product Information: Version: 1.0.4 Commit SHA-1 hash: af1e6684fd

Runtime Environment: OS Name: Mac OS X OS Version: 10.13 OS Platform: Darwin RID: osx.10.11-x64 Base Path: /usr/local/share/dotnet/sdk/1.0.4

VS Code version:

1.27.2

C# Extension version:

1.16.1

Steps to reproduce

I don’t have a simple repro. In my project, if I open the “Shooter.cs” file then it’s fine. If I open the “Rifle.cs” file it’s still fine. If I then click back on the open Shooter.cs file I get about 400 spurious errors.

Expected behavior

Only real errors should be reported.

Actual behavior

Almost every line of the file is reported as an error. This is the error on the rifle class itself:

The type 'Rifle' in '/Users/simonwatson/Documents/Projects/swatson_OSX_SVT2/Assets/Scripts/Rifle.cs' conflicts with the imported type 'Rifle' in 'Assembly-CSharp-firstpass, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'. Using the type defined in '/Users/simonwatson/Documents/Projects/swatson_OSX_SVT2/Assets/Scripts/Rifle.cs'. [Assembly-CSharp]
The type 'Rifle' in '/Users/simonwatson/Documents/Projects/swatson_OSX_SVT2/Assets/Scripts/Rifle.cs' conflicts with the imported type 'Rifle' in 'Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'. Using the type defined in '/Users/simonwatson/Documents/Projects/swatson_OSX_SVT2/Assets/Scripts/Rifle.cs'. [Assembly-CSharp-Editor]

This is from a reference to the rifle in the Shooter class:

The type or namespace name 'Rifle' could not be found (are you missing a using directive or an assembly reference?) [Assembly-CSharp, Assembly-CSharp-firstpass, Assembly-CSharp-Editor]

(This is most of the errors)

This is a reference in Shooter to an external enum:

Cannot implicitly convert type 'Shooter.LaserType [Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]' to 'Shooter.LaserType [Assembly-CSharp-Editor, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]'. An explicit conversion exists (are you missing a cast?) [Assembly-CSharp-Editor]

This is the output from omnisharp when loading up:

Quick Update: Unity 2019.2 officially added support for VS Code via package manager. To ensure projects are generated correctly, remove all csproj files that are related to the unity project and reopen the the project from Unity in order to properly generated the proj files. You might also want to remove any old .vscode directory just to be sure that a clean vs-code compatible is generated from unity.

Will come with updates after I test this for a few days

@Aciho I think I might know what is the problem here. Do you have symbolic links in your project? Can you try setting omnisharp.path: “1.32.2” in your settings and then Ctrl+Shift+P --> Restart OmniSharp and see if the error still reproduces ?
