Omnisharp doesn't start up when c# project is in OneDrive folder with "File On-Demand" on

Environment data

dotnet --info output: 2.0.2 VS Code version: 1.17.2 C# Extension version: 1.12.1 Windows Version: Windows 10 1709 (OS Build 16299.19) It has a new OneDrive feature “File On-Demand”

Steps to reproduce

1. Close all VS Code windows/applications if any.
2. Make sure the OneDrive Setting “Files On-Demand” is on.
3. Create a simple “Hello World” console app in OneDrive folder: dotnet new console
4. Open the new created project in VS Code, open “Program.cs” file

Expected behavior

OmniSharp should start up.

I moved the “HelloWorld” project out of OneDrive folder, then it worked.

Actual behavior

OmniSharp doesn’t start up.

Visual Studio 2017 has similar problem when a project is in OneDrive folder no matter if “File On-Demand” is on or off. I guess Omnisharp would not start up as long as the project is in OneDrive folder even if “File On-Demand” is off.

Same on my end, vscode x64 1.18.0

i’m having this problem right now; when I open the solution with VSCode on Ubuntu, Omnisharp doesn’t start, but when I do it on Windows, it works

edit: holy hell, i just figured that this configs on the settings of VSCode were making Omnisharp not working:

"files.exclude": {
    "**/obj": true,
    "**/bin": true,
    "**/*.csproj": true,
}
