No mention of RazorLangVersion on this page even though warnings point to this page about it

[Eilon]

I'm building a project that uses .razor files for the purpose of #blazing and I got this warning:

Warning RAZORSDK1005 One or more Razor component files (.razor) were found, but the project is not configured to compile Razor Components. Configure the project by targeting RazorLangVersion 3.0 or newer. For more information, see https://go.microsoft.com/fwlink/?linkid=868374

If you go to https://go.microsoft.com/fwlink/?linkid=868374, it takes you to this doc (https://docs.microsoft.com/en-us/aspnet/core/razor-pages/sdk?view=aspnetcore-2.2), which doesn't mention RazorLangVersion at all.

It would be nice to have a mention of it, and showing where/how to put it in the CSPROJ.

same issue here
trying to build a component library

Compiles, but can not be used by reference in Visual Studio Solution with both Projects.

Component builds, the dll is there, but is the .Razor included?
