Awaiting a new release for VS2019

Small update, I was able to change Microsoft.VisualStudio.BlazorExtension to support VS 2019. It builds and installs fine, but, there are few problems:

1. Future versions of VS will not support AutoLoad enabled solutions. Extension need to be migrated to use AsyncPackage. But this can be done later as VS 2019 only warns about this. (At least at this point it does.)
2. Although my Blazor project builds and runs just fine with the extension in VS 2019, it seems that TagHelper syntax highlighting does not work.
   
   Same for the base class methods:
   
   It feels like it does not know it inherits BlazorComponent.
   Just to be sure I checked MVC project, and TagHelpers work there with BlazorExtension the extension installed.

I would appreciate any ideas on where in the code I can look to debug the second issue.

VIsual Studio version: 16 preview 1

This is done 👍 - this will be going on in VS 2019 preview 2, but will require updated runtime packages/templates to work. Stay tuned for announcements when we release the next set of previews.

@rynowak VS 2019 preview 2 has been released. But even https://dotnet.myget.org/F/blazor-dev/vsix/ still contain vs 2017 version only.

Yes, we have some enabling features in VS 2019 preview2. Expect to see some new stuff when .NET Core 3.0.0 preview2 (soon). We'll make an announcment when stuff is ready to use.
