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
[Solved] In my updated Visual Studio 2017 Enterprise 26430.13 i solved my problem with disable and re-enable Razor Language Services and it's working now.
I know that's little weird. I find Razor Language Services in Extension and Update from Tools menu and Disable it and restart Visual Studio and Enable it again and restart Visual Studio again and finally everything's right.
