CI OSX temporary failed

@rkeithhill Any thoughts?

@iSazonov The problem with putting this in the docs is that few people read the docs. That said, it's better to have in the docs than nowhere. :-) But at some point, I suggest we either add a .vscode\settting.json for this project or perhaps even better, add a .editorconfig file in the root dir. This is a config file that supports multiple editors. VS 2017 supports this file and VSCode does if you install the EditorConfig extension.

This brings me to my next suggestion. Consider adding a .vscode\extensions.json file which will prompt VSCode users to install the "recommended" extensions for this project. Perhaps with contents like this:

{
    // See http://go.microsoft.com/fwlink/?LinkId=827846
    // for the documentation about the extensions.json format
    "recommendations": [
        "ms-vscode.csharp",
        "ms-vscode.powershell",
        "EditorConfig.editorconfig"
    ]
}

@rkeithhill Thanks for great feedback!

I think we should be more conservative - other developers might have their preferences and we shouldn't overwrite them.

Keep in mind that the use of a "workspace" specific settings file only overrides "user" specific settings for that workspace. And that is typically what you want. That is, a user might prefer tabs to spaces but this project uses spaces. So adding that setting to an editor config file will ensure that spaces are used for this user in only this workspace. In his own projects, tabs will still be used.

@rkeithhill The PR is for docs only. I believe your suggestions is great for new PR. Could you please open it?
