Visual studio не подчеркивает ошибки

I recently upgraded from Visual Studio 2012 to 2017 (updated to version 15.3.5) and have some issues with the IDE.

In a certain project, I don’t get error underlining.

and in the Error List pane, «Build Only» actually shows more information than «Build + IntelliSense»

Also, with «Build + IntelliSense» selected, I can only see the compiler error in the Output window. Here is the error list after a failed build

but the output window has this:

3>—— Build started: Project: …, Configuration: Debug Any CPU ——

3>C:Checkout…MainForm.vb(454,27): error BC30311: Value of type ‘Module1.aClass’ cannot be converted to ‘Module1.bClass’.

This doesn’t happen on all projects. I made a new project to see if I could reproduce, and I can’t. Here is a new project with the same code, where the error is underlined in code and «Build + IntelliSense» works.

I have even sorted the xml in the vbproj files and «diffed» the offending project vs the new project, and there is no obvious difference which would cause this. Both reference the same compiler. Both projects target .Net 4.6.2 and are set to compile for x86 only. The offending project references a few other projects (C# and VB.Net) plus a third party dll and a nuget package. Aside from these differences there is nothing else.

Other projects (C# and VB.Net) in the offending project’s solution work fine.

I have seen similar issues talked about online but no fixes have worked for me. I have tried the «Repair» option in the installer. I then uninstalled Visual Studio and reinstalled.

Update:

Changing the target framework seems to have some effect. A project with this behavior was targeting 4.6.2 and showing no errors, and when it was changed to 4.7, it showed a compile error. Then changing back to 4.5 it showed an error. Then changing back to 4.6.2 it showed no errors. Repeating the process proved to be non repeatable. 4.7, 4.5, 4.6, 4.6.2 — whatever, now all show no errors.

It’s also important to link this Microsoft page https://developercommunity.visualstudio.com/content/problem/7759/no-errors-displayed-in-the-error-list.html as many other people seem to have a similar issue.

I haven’t touched them since the last update and highlighting stopped working.
--user-data-dir with this highlighting works. soo, should I delete my settings and start over?
