omnisharp-vscode can't find dotnet installation on RedHat in Remote Development SSH mode

Swimburger commented 4 years ago

C# Extension/Omnisharp VS code extension won't find .NET installation on freshly installed RedHat vm with .NET Core 3.1 setup.

Environment data

dotnet --info output:

.NET Core SDK (reflecting any global.json):
 Version:   3.1.100
 Commit:    cd82f021f4

Runtime Environment:
 OS Name:     rhel
 OS Version:  7
 OS Platform: Linux
 RID:         rhel.7-x64
 Base Path:   /opt/rh/rh-dotnet31/root/usr/lib64/dotnet/sdk/3.1.100/

Host (useful for support):
  Version: 3.1.0
  Commit:  65f04fb6db

.NET Core SDKs installed:
  3.1.100 [/opt/rh/rh-dotnet31/root/usr/lib64/dotnet/sdk]

.NET Core runtimes installed:
  Microsoft.AspNetCore.App 3.1.0 [/opt/rh/rh-dotnet31/root/usr/lib64/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 3.1.0 [/opt/rh/rh-dotnet31/root/usr/lib64/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download

VS Code version: 1.41.0 C# Extension version: 1.21.9 Remote - SSH Extension version: 0.45.0 Red Hat version: Red Hat Enterprise Linux Server release 7.7 (Maipo)

Steps to reproduce

Create fresh Azure RedHat VM:

az group create -n rhtest -l eastus
az vm create -n rhtest -g rhtest --image RedHat:RHEL:7.7:7.7.2019090316 --generate-ssh-keys

SSH into RedHat VM and follow RedHat getting started guide:

sudo yum install scl-utils
sudo yum install rh-dotnet31 -y
scl enable rh-dotnet31 bash
dotnet new console -o hello-world

Add source scl_source enable rh-dotnet31 to ~/.bashrc.

Connect VS Code Remote Development SSH to Redhat VM at ~/hello-world. At this point C# extension detects a .NET project but fails due to not finding the .NET Core installation.

Expected behavior

C# extension/omni sharp finds .NET Core installation.

Actual behavior

.NET Core installation not found, console output:

My current workaround is to find where the dotnet executable is and create a symlink in ~/bin/dotnet. To find executable: which dotnet To create link sudo ln -s /opt/rh/rh-dotnet31/root/usr/bin/dotnet ~/bin/dotnet.

Close VSCode and re-open VSCode connecting to the Red Hat at ~/hello-world.
