C# Extension fails only for netcoreapp3.0 GA #3289
Comments

what is the content of your csproj file? the warning says that you have 'Microsoft.NETCore.App' there which is not needed in 3.0. also can you please set omnisharp.logginglevel to "debug" and post the output again? |

I have the same issue both on Windows 10 Enterprise Edition and Fedora 30. Both environments are updated and the latest versions of VSCode, C# Extension and .Net Core SDK are installed. Please see below the logs from my Fedora 30 machine: LogsOmniSharp log

It might help if I add that everytime I open a netcoreapp3.0 application, C# extension keeps showing the following message: "There are unresolved dependencies. Please execute the restore command to continue." Any help would be highly appreciated. |

can you post the content of the csproj file? This is what I see: when using: |

I would really like to help but I can't reproduce this on any system 😀 The warning I will continue to look into this but it would be great to get any more info from anyone experiencing this. |

I looked in folder "/home/masoud/.vscode/extensions/ms-vscode.csharp-1.21.3/.omnisharp/1.34.3/omnisharp/.msbuild/Current/Bin/" to see if I have MSBuild version 16 there. I checked the MSBuild.dll.config file and the contents of this file looks wrong. It looks like the MSBuild located in the path that C# extension is referencing it is version 15 not 16? Thanks. |
|
It is version 16, however MsBuild 16 has assembly version 15.1. |
|
I see! Thanks :) |
|
If you are on Linux or MacOS you may want to try install Mono 6.0.0 https://www.mono-project.com/download/stable/ |
|
Thank you. File contentsOmniDemo.csprojProgram.cs |
|
No, the built in MsBuild is given preference over Visual Studio 2017. |
|
And I checked: No VS 2019 installed, nor previews. |
|
can you also post the contents of the |

Sure, and screenshot of VS Code - coming up in a moment - - - |

if you are Windows, I believe the workaround will be to install Visual Studio 2019 (latest - 16.3) https://visualstudio.microsoft.com/vs/ |
|
OK, will do. Right now checking MSBuild's in my path. |
Really! I goes to updated my VS 2019, and all problem are fixed. |
|
Thanks a lot for confirming 👍 If anyone experiences this problem on *nix platforms I believer this should help too #3289 (comment) OmniSharp ships with an embedded MSBuild which for various reasons is somewhat limited - it should work however for more basic scenarios like shown here. If we find VS2019 (Windows) or Mono 5.18.1+ (Linux, MacOS) on the machine, we use that instead. We are investigating how we can bring the embedded MSBuild up to speed here and what goes wrong there. |
I'll give this a go once I'm back home. |

I'm experiencing the same issue on Ubuntu 18.04. But I open in vscode 1.38.1 with ms-vscode.csharp extension version 1.21.3 I get the same warning as other people in the OmniSharp Log: I also get unresolved dependencies asking me to restore and intellisense not working with lots of errors similar to the following one: Installing mono-devel from Mono 6.0.0 Stable (https://www.mono-project.com/download/stable/) fixed the issue, but it needs another 365 MB disk space. |
Still not working on my Windows 10 even with VS19 installed. Please see the OmniSharp log below: |
|
AND - Install VS 2019 Community edition solved issue on my laptop as well. |
|
Just a note that if I uninstalled dotnet-sdk-2.2 (so that I only have dotnet-sdk-3.0 installed) I get a different error in the OmniSharp Log: I could then fix the issue by making omnisharp use the legacy SDK resolver as mentioned in #3160 (comment) |
|
I think, that best way to solve the problem is to wait till OmniSharp will roll-out the uppdate for their extension with standalone 16.0+ msbuild package. As for me, I see, that extension uses this one: |
|
This is my OmniSharp log after uninstalling all other .net core sdks and only having version 3 installed: |
|
you could try adding and see if it helps |
Thanks. It helped! |
|
Guys, I've got the solution (for those, who don't want to install VS2019).
After it I get this output: So correct version of MSBuild is now used by OmniSharp. But don't forget about step 3, solution need .Net Core 3.0 SDK for VisualStudio. |
|
I got it fixed on Fedora 30 just by removing .net core 2.2 and only having .net core 3 installed. |
|
While working with Blazor, adding omnisharp.json wasn't enough, I had to install de 2019 build tools.
I'm using Chocolatey, so to do this I installed visualstudio2019buildtools and visualstudio2019-workload-netcorebuildtools. Anyone who uses it probably would just need the to install the last one, because it already has the first as a dependency. :) |
|
Uninstalling all but 3.x and doing the comment by @filipw worked for me on Windows. |
|
For anyone finding this a bit later. I was using VSCode on Mac OS.... I had mono 6.0.0 installed and had the red lines everywhere. Upgraded to 6.4.0 stable (Visual Studio Version) and it's working great. No red lines. |
Issue Description
C# Extensions complains "The type or namespace name 'System' could not be found ..." (likewise System.String, System.Object, System.Void, etc.)
This happens only when Target Framework = netcoreapp3.0.
No problems for netcoreapp2.0, netcoreapp2.1, nor netcoreapp2.2.
Code builds and runs fine at command prompt.
Steps to Reproduce
dotnet new consoledotnet build=> builds successfullydotnet run=> runs successfullyExpected Behavior
C# Extensions displays c# code without any errors independent of whether TargetFramework = netcoreapp3.0, 2.2, 2.1, or 2.0.
Actual Behavior
C# Extensions accepts code for 2.0, 2.1, and 2.2.
For netcoreapp3.0 completely different behavior => C# Extensions complains of syntax errors (no type or namespace name) for System, System.String, System.Object, System.Void, etc.
