Hi @TomaszGrzmilas thank you for reporting this issue! Would you mind providing a simple repro app for us to investigate further?

Hi,

Here is a repo https://github.com/TomaszGrzmilas/VSTest.
It is not building since, when I open Pages -> Applications.razor and start to edit it, application stop working.

We most likely fixed your issue in the 16.8-Preview1 milestone @TomaszGrzmilas! I can't promise that we did only because I don't have all the C# data:

Butttt I doubt that'd cause a crash 😄 . That release should be coming out in the next week or so!

Hi @NTaylorMullen

Just installed VS 16.8-Preview 1.0 and still opening Applications.razor crash Visual Studio :(

Would you mind reproing it with VS' feedback tool (it should capture a dump) and link the issue it creates so I can investigate further?

Ahhhh, ok I have a better idea of what's going wrong then. Thank you so much for your patience and help in investigating this issue. We definitely want to make sure we get things working for you 😄.

Would it be possible to share that application with me privately? If not I totally understand and we can go other routes. Things I'd be curious about:

1. In your obj/Debug/ folder do you have a project.razor.json? If so would you mind including that here?
2. If you set the environment variable RAZOR_TRACE to Verbose you should get a new Razor Language Server Client entry in your output window:
   
   Could you include those contents here?

@NTaylorMullen

No problem :)

In attached archive there are:

• project.razor.json
• ActivityLog.xml - I get Null Reference Exception in VS while gathering information for you,
• Output.txt - Razor Language Server Client output after opening project,
• Output_2.txt - Razor Language Server Client output after opening Application.razor (I think there is some infinite loop).

• Output_2.txt - Razor Language Server Client output after opening Application.razor (I think there is some infinite loop).

Hmm, ya there's loadddssss of logs in that Output_2.txt. Out of curiosity, how long was the document open before capturing that log? Only asking because the semantic token pieces do poll every few seconds so seeing it repeatedly makes sense; however, that amount of logs would not make sense if you just had the file open for a brief period of time.

Would you mind providing the log output after typing @DateTime.Now and <strong></strong>? That might give some insight as to why you're not getting any IntelliSense.

File opened instantly, I was doing nothing, just watched log scrolling, I was thinking that it eventually stop but it didn't. This is why I wrote that I think there is some infinite loop.

• Output-RazorLanguageServerClient_1.txt - on open document Application.razor I started typing @DateTime.Now and <strong></strong> (I get no IntelliSense)

• Output-RazorLanguageServerClient_2.txt - I created empty razor Component and I started typing @DateTime.Now and <strong></strong> (I get no IntelliSense)

@dibarbet is there a way we can acquire C# LSP logs? I'm looking at the logs @TomaszGrzmilas has provided and all is looking good from our end so I'm curious if C# is having issues.

@TomaszGrzmilas would you mind providing the Html Language Server Client log in the output pane when typing <strong></strong>. Oh and again, you're the best for hanging in there with me. I know this is probably annoying as hell but man you're definitely helping shed some light on gaps in our log gathering + potentially how the new editor falls part. Thank you!!

@NTaylorMullen I'm just a humble tester of your great work :) I'm glad that I can support the development of this great software to a small extent.
