ASP.NET Core Tag Helper Intellisense in Visual Studio 2017

Question

I am unable to get Intellisense for all tags (e.g. asp-for asp-action, etc.) I'm running Visual Studio 2017.

My .csproj file includes the following packages:

<PackageReference Include="Microsoft.AspNetCore" Version="1.1.0" />
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Mvc.TagHelpers" Version="1.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Razor.Tools" Version="1.1.0-preview4-final" Type=""/>
<PackageReference Include="Microsoft.AspNetCore.Razor" Version="1.1.0" />
<PackageReference Include="Microsoft.AspNetCore.Razor.Runtime" Version="1.1.0" />

and my _ViewImports.cshtml file includes the following:

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

Is there something I need to edit or add?

For VS2017 RTM (if you've upgraded by now) you need to install Razor Language Services from Extensions and Updates... in Tools menu within Visual Studio.

Caveat: It seems as if you also have to remove any Microsoft.AspNetCore.Razor.Tools reference (I had version 1.1.0-preview4-final) from your .csproj file to enable IntelliSense after installing the extension above.
