Create a folder on my local machine that will contains my project
Open this folder inside vs code
Use the remote-container extension :
- Add Development Configuration file : C# (.NET Core Latest)( mcr.microsoft.com/dotnet/core/sdk:latest )
- Reopen folder in container
Create project inside the container : dotnet new mvc
Open any CS file and wait for Omnisharp installation
Open any CSHTML file and try to write some html but got no intellisense for both html or razor syntax

Description of the problem:

No intellisense inside cshtml files

Expected behavior:

Want to have html and razor intellisense

Nothing

Edit: I was not sure so i tried with a simple Dotnet Core Razor WebApp and YES, it's not working.

More or less the same here. New ASP MVC project (net core 3 preview 8), remote Ubuntu 18.04 via SSH:

When I open a .cshtml file, I got no Intellisense. The same is for .razor files for a Blazor project. What I've observed is that the log of the Razor Log on VSCode shows a crash:

Razor.VSCode version 1.0.0-alpha3-20190627.5
--------------------------------------------------------------------------------
Razor's trace level is currently set to 'Off'
 - To change Razor's trace level set 'razor.trace' to 'Off', 'Messages' or 'Verbose' and then restart VSCode.
 - To report issues invoke the 'Report a Razor issue' command via the command palette.

I've checked the obj/Debug/netcoreapp3.0/project.razor.json file and it seems correct. The only peculiarity is that it shows some values containing a \n ("Documentation" keys). Attached is the full file.

Hah, honestly @Peluko I'm shocked you got that far 😄, enabling remote Razor development issomethingg we want to do but haven't put any time into as of yet.

@NTaylorMullen Hey there, I'm having the same issue highlighted above, but with WSL. I'm wondering if it is a bug or is this a feature not implemented yet?

Thank you for the work on the extension 😄

Hasn't been implemented yet 😄. I hear you though, we want to get this working too!

NTaylorMullen on 11 Sep 2019

I'm not able to get any Intellisense on .cshtml files. For HTML, CSS, and JS, I get syntax highlighting but no intellisense. For Razor, it's shows default text color.

Auto-detect has the language set to aspnetcorerazor and I tried switching to HTML (C#) and that didn't change anything.

I've changed a bit the title cause it's also not working for a 'simple' Dotnet Core Razor WebApp. So now, the issue title is more globaly.

When I open a .cshtml file, I got no Intellisense. The same is for .razor files for a Blazor project. What I've observed is that the log of the Razor Log on VSCode shows a crash:

Razor.VSCode version 1.0.0-alpha3-20190627.5
--------------------------------------------------------------------------------
Razor's trace level is currently set to 'Off'
 - To change Razor's trace level set 'razor.trace' to 'Off', 'Messages' or 'Verbose' and then restart VSCode.
 - To report issues invoke the 'Report a Razor issue' command via the command palette.

Hey all, thanks for the reports! We've yet to add full support for remote development but are hoping to get it done soon!

One of the blockers for this was a bug on vscode https://github.com/microsoft/vscode/issues/86901 which will be fixed in the next release. I'm still investigating if there is any other work that needs to be done here.

ajaybhargavb on 13 Dec 2019

@ajaybhargavb Glad to hear that bug is getting squashed. There might be other work that needs to be done because even when the language is properly set it aspnetcorerazor instead of Razor, the syntax highlighting is still a bit off.

Take this razor component for example:

Notice the closing </p> on line 10, or the C# code on lines 15 and 17.

Btw I generated the example above inside a vscode project that's not running inside remote containers, so Omnisharp used the host mono framework and had no issues switching to aspnetcorerazor:
