Interesting that spell checking is returning items seen by the error list but actual diagnostics are not. |
|
Unfortunately, I can't repro this, and all errors seem to be working for me. Granted I am using a newer version of VS. My build of 17.13 P2.1 seems to be completely broken so I need to fix that first, before I can try there @Peter-Juhasz don't suppose there is anything interesting in the Razor Log Output? The fact that spell checking, completion and nav bars are working, but not diagnostics, is quite surprising. |

I did not find anything suspicious, here is the full log from start of VS and opening the file:

Possible duplicate of https://developercommunity.visualstudio.com/t/Errors-are-not-reported-in-Razor-files/10822934. In that report, both Roslyn and Razor are seeing an exception in diagnostics: @Peter-Juhasz do regular C# diagnostics work in the same project? If not, it could be the same issue. |

Roslyn works fine, diagnostics are missing only in Razor files. I don't see any errors in ActivityLog.xml either. Is there any other place I could look for potential logs? It is also strange that this issue is not present on my notebook (same VS version, same user profile synced, same Windows user/policies). |

I was able to find the same exception in the file named |

Out of curiosity, is it present anywhere in a Either way, I'll monitor the above linked VS Feedback issue, which is with the Roslyn team to investigate, and will keep you posted here. |

Yes, it is in a file named <System xmlns="http://schemas.microsoft.com/2004/06/windows/eventlog/system">

Thanks. It's surprising to me that regular C# diagnostics work even though that is reported, but I don't claim to understand all of the moving pieces here. |
|
Yes, it does! Although, I had a strange experience yesterday, where diagnostics were at the very least delayed. It was a small 2 files console app, and first I thought I'm experiencing this issue, but after like 10 seconds the diagnostics/squiggles appeared in the editor. I'm not sure I was experiencing this issue, or it was related to this one (a fatal exception may not resolve even after any delay), but that was the only similar symptom I experienced so far. |

VS 17.13 P2.1 with no extensions enabled

No errors are displayed as squiggles, in the Error List or on the scroll bar. Both markup and embedded C# are affected.
HTML and C# alone works fine, reporting errors as expected.
