Omnisharp-roslyn: OmniSharp chokes on project containing Protobuf element

Created on 8 May 2019  路  16Comments  路  Source: OmniSharp/omnisharp-roslyn

While trying out the new ASP.NET Core gRPC features in Visual Studio Code I noticed that I'm getting errors in the OmniSharp Log in VS Code after adding the Protobuf element to my project file. Interestingly this only seems to fail for the client project and not for the server project. I've followed the documentation to ge the client going. But once I add the element I get the following error in my output:

[warn]: OmniSharp.MSBuild.ProjectManager
        Failed to load project file '/workspaces/aspnetcore-grpc/Client/AspNetCoreGRPC.Client.csproj'.

This is really annoying :/

I have lost my intellisense in VS Code since adding some Mono to my project. This really hurts productivity for me. It there no temporary workaround?

Which version of OmniSharp are you using?
Also, can you post the full output of the OmniSharp log? thanks!

@filipw Sure thing. I'm running omnisharp 1.32.18 according to the logs, as part of the VS Code C# extension version 1.19.0. Here are the logs:

This is also happening with the OmniSharp on the latest C# Extension in Visual Studio Code on OSX.

This issue also happens to me, but it just happens when I install "serilog" package

tungphuong picture tungphuong on 25 Jul 2019

gRPC MSBuild tooling developer here. What happens is, with a near certainty, is the build tasks DLL from the package links at runtime to the wrong version of Microsoft.Build.Utilities, specifically the one that comes with Mono/XBuild rather than that from the Microsoft's MSBuild package. XBuild's MSBuild emulation assemblies notoriously lack some methods, so we're unlikely runnable against them.

Do you think it's possible to change this behavior within OmniSharp?

This is really annoying :/

I have lost my intellisense in VS Code since adding some Mono to my project. This really hurts productivity for me. It there no temporary workaround?

For anyone still experiencing this issue, I've found a workaround that works for me on OmniSharp for OSX, Version = 1.34.5. It would seem that the root cause of the issue was found, but the fix in #1595 does not help me.

So far, the only solution for me has been to remove Microsoft.Build.Tasks.v4.0 and Microsoft.Build.Utilities.v4.0 libraries from the Mono GAC in Omnisharp.

Following the steps below has fully restored Omnisharp functionality for me in VSCode gRPC/Protobuf projects:

  1. Find the path which leads to your Omnisharp extension. Example: ~/.vscode/extensions/ms-vscode.csharp-1.21.5/.omnisharp/1.34.5.
  2. Open the lib/mono/gac/ folder within the Omnisharp directory.
  3. Delete the Microsoft.Build.Tasks.v4.0 and Microsoft.Build.Utilities.v4.0 folders.
  4. Add "omnisharp.useGlobalMono": "never", to your VSCode settings.json.
  5. Restart Omnisharp.

This is a brutal way to solve the problem, but it's allowed me to get back to work.

@radical, since you worked on #1595, I'm wondering if my solution might give you more insight on how we can bypass the old MSBuild libraries.

The workaround suggested by @nagytech has worked for me as well, working on Ubuntu and with Omnisharp 1.34.5

the fix from #1595 has not been shipped yet because it was applied to the embedded mono build which hasn't been changed yet.
it will ship only once #1640 is merged

Thanks for the update @filipw.

I thought I would be able to build from master and that would solve the issue, but that doesn't seem to be the case. Is that correct?

nagytech picture nagytech on 30 Oct 2019

Looks like #1640 has been merged and deployed on November 6 (1.21.7) but this problem persists for me.

Verified that I am using the right version of mono "OmniSharp server started with Mono 6.4.0." but receive the following in the log.

  4. Add "omnisharp.useGlobalMono": "never", to your VSCode settings.json.
  5. Restart Omnisharp.

This file structure is not present for me in the recent omnisharp releases

# nils @ elMaco in ~/.vscode/extensions/ms-vscode.csharp-1.21.8 [13:47:59] 
$ find . | grep Microsoft.Build.Tasks.v4.0
./.omnisharp/1.34.8/omnisharp/.msbuild/Current/Bin/Microsoft.Build.Tasks.v4.0.dll

./.omnisharp/1.34.9-beta.10/omnisharp/.msbuild/15.0/Bin/Microsoft.Build.Tasks.v4.0.dll

However, setting the

    "omnisharp.useGlobalMono": "never",

in settings.json seems to help!

I also deleted all previous omnisharp packages in ~/.vscode/extensions/ms-vscode.csharp-1.21.8/.omnisharp, not sure if this was part of the solution.

koliyo picture koliyo on 7 Dec 2019

The fix was deployed and shipped however it only affects running on local (not global) Mono.
Therefore the setting "omnisharp.useGlobalMono": "never" is necessary to see the result. Alternatively, it also works if no Mono 6.4.0+ is found on the machine.

Unfortunately, this fix no longer helps. It produces different error:

Microsoft.Build.Exceptions.InvalidProjectFileException: The SDK 'Microsoft.NET.Sdk.Web' specified could not be found.
