NTaylorMullen · 2021-06-27T20:20:58Z

@danroth27 could you include the O# logs?

jtsom · 2021-06-28T17:39:03Z

FYI ... I do not see this with Blazor Server app, but do see problems with a BlazorWasm app (as detailed in dotnet/vscode-csharp#4618)

danroth27 · 2021-06-28T20:57:26Z

@NTaylorMullen Added O# logs. Need anything else?

eustachi0 · 2021-06-29T17:26:10Z

I hope this help

danroth27 · 2021-07-08T19:49:49Z

🎉

- This fixes https://github.com/dotnet/aspnetcore/issues/33858 but requires latest O# Roslyn to work properly.

jtsom · 2021-07-19T12:35:08Z

This is NOT fixed in v1.23.13:

danroth27 · 2021-07-19T16:53:27Z

@jtsom I'm unable to reproduce this issue anymore with 1.23.13. Could you please open a new issue for the problem you are seeing using the "Razor: Report a Razor issue" command in VS Code? This will collect the logs that we need.

Xeevis · 2021-07-19T17:06:07Z

This is NOT fixed in v1.23.13

Had this same problem, took the easy route and just deleted cache, bin, obj, VS code app data and it went away. 🤷🏻‍♂️
