Intellisense for CSS is lost when intermingling razor code in a style tag about razor

[rynowak]

Does this work in the HTML editor (non-Razor)?

Oh man, how this one bugs me. VSCode suffers from similar behavior.

The HtmlEditorDocument delegates to the Microsoft.Web.CSS libraries for <style> tags' contents via a CSS BlockHandler , and those libraries' parser does not have any concept of embedded languages or artifacts. That being said, funny enough, the JS BlockHandler specifically excludes text ranges identified by Razor from being included in the text snapshot that the JS library gets to work with. It looks like there may be some extensibility point with ParserItemFactory or something like that, but by the time I found that I was too deep down the rabbit hole and decided to bail out.

@NTaylorMullen if you are convinced this is a bug on the non-OSS side, please find the internal bug and link it 😆

I've posted this as an issue in Visual Studio Community and here (the old here) at least twice over the last two years. I can't find the posts. There was a little investigation done at some point I think. Someone on the team said they had a similar problem with script (IIRC) tags, and thought the same approach might work. But that was the last comment. It's my dotnet/aspnetcore#1 issue with Razor. I even put it as a reason I thought the new VS wasn't ready to go live in one of those pop-up questionnaires only a couple of months ago. Not only does intellisense quit working for autocomplete, all of the code goes white.

Hi. Thanks for contacting us.
We're closing this issue as there was not much community interest in this ask for quite a while now.
