Only one restore prompt should come, from the selected project file.

Actual behavior

Two prompts are coming to restore

We still support project.json in VS Code and it's entirely possible that you might use VS Code with partially-converted code base. So, it's actually pretty tricky to determine whether project.json files should be restored or not (and not break something else). This isn't a great experience, but it's sort of working as designed.

Is there a configuration setting that can set somewhere? I am using VS Code but I still need to support VS2015.

If you want to disable processing of project.json projects, you can add an omnisharp.json file to your root folder with the following content:

{
    "dotnet": {
        "enabled": false
    }
}

Looks like there's a workaround for this problem. Closing the issue--feel free to open a new one if you're still having problems.
