How can I add an COM reference into a c# proj in vscode

[shikouzhong]

Yes, we can add a nuget package using the dotnet comand line, but I don't know how to add a COM reference in vscode, just as in vs community and is it supported in omnisharp-vscode?

I have searched the stackoverflow, but no right answer for c# proj in vscode.

-VSCode Version: 1.23.0
-OS Version: Windows 10 1803

It sounds like this is really a .NET project question rather than C# for VS Code. Assuming that your project targets .NET Framework, I would expect a legal <ComReference /> in your project to just work on Windows, but I'm unsure of the level of support for them in the .NET Core SDK. If they're supported, there's certainly not a gesture to add them to the project today.

A lot of time has passed since this was posted, but the issue basically boils down to this msbuild issue. The dotnet CLI doesn't support it. I'm currently investigating a workaround using MSBuild for VS 2019 without the IDE. I finally got it to work with the following in my tasks.json file, using msbuild instead of dotnet

    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "msbuild",
            "args": [
                "/property:GenerateFullPaths=true",
                "/t:build",
                "/consoleloggerparameters:NoSummary"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "presentation": {
                "reveal": "silent"
            },
            "problemMatcher": "$msCompile"
        }
    ]

And in the csproj file, in my case, I needed to force the platform target to x86

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <PlatformTarget>x86</PlatformTarget>
  </PropertyGroup>
