How to set default namespace in a .NET core 2.1 project

Question

I finally have the opportunity to play around with .NET Core in Visual Studio Code on MacOSX, but obviously a lot of things are different compared to the oldschool .NET Framework/Visual Studio way.

For starters I have not had any luck finding a way to set a default namespace in my .NET Core 2.1 project.

I have tried changing the project name in the .sln file to RootNS.ProjectName instead of the default ProjectName, but although the project name in Solution Explorer is reflecting my change, it does not set the expected namespace when creating new classes - it seems to only follow the folder name.

Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "RootNS.ProjectName", "ProjectName\ProjectName.csproj", "{443D0B42-6E6C-4DC6-8E42-E90FFCEBD448}"

Am I too naive to even think this is possible?

Thanks!

Edit:

I have already tried adding the RootNamespace element to the .csproj file like so:

<PropertyGroup>
  <TargetFramework>netcoreapp2.1</TargetFramework>
  <RootNamespace>RootNS.ProjectName</RootNamespace>
</PropertyGroup>

I use Visual Studio Code on MacOSX.

The answer is going to depend upon the C# plugins you happen to be using with Visual Studio. I've used the <RootNamespace>RootNS.ProjectName</RootNamespace> in the past but it did not work on both Windows and Linux for me. I was using one of the many c# Extensions plugins. Not sure which on.

I am using VS Sharper for C# plugin now. It has a configuration file called "vssharper.json" where you can add things like

{
    "namespace": "Answers.Hello"
}

That works for me in Windows and Linux. I'd try that on your Mac.
