Description
Type: Bug
For over a year, I've dabbled with the C# and C# Dev Kit extensions, and I always wondered why C# provided an incomplete list of errors in my open solution. Visual Studio has no problem with this.
I finally figured out over the weekend that there's a setting that controls this:
Extensions -> C# -> Text Editor -> "dotnet > Background analysis: compiler diagnostics scope"
(and "Analyzer diagnostics scope")
Changing this from openFiles to fullSolution did the trick. Now I'm much more likely to use C# Dev Kit in VS Code since I can rely on the Problems tab to give me an exhaustive look at issues, like VS does by default
My complaint though, is that this isn't very discoverable. VS and VS Code have different defaults for this, and I don't find that intuitive. The only reason I even went looking in VS Code settings was because I happened to know that VS has a similarly buried feature that lets me turn up or down the analyzer diagnostic scope.
Can VS Code's default for C# errors be changed to report on the whole solution?
