Issue with using namespace where name is X.Y.Z.Windows

[zeekbrown]

Type: Bug

In a partial class CustomComponent : ComponentBase, a namespace is being reported as unessary (IDE0005: using directive is unnecessary). The namespace is "App1.Features.Home.Windows" and using a class from the namespace works when compiling/running the app; but VSCode reports it as an issue. Nesting the namespace one level deeper, resolves the issue so App1.Features.Home.Windows => App1.Features.Home.Windows.Test. Visual Studio does not have the same issue if the project is opened there instead of VSCode.

Moving to "area-roslyn" as this involves live diagnostics.

@zeekbrown Can you share a screenshot? It might make sure we're on the same page of the repro here, but also I'm curious if you're seeing other types or members in the file as having the correct colors and things like that.

[zeekbrown]

These are the only lines with incorrect colors / warnings in the file. The screen shot is three separate images stitched together so you can see all warnings / color issues easier. When this was a single .razor file everything worked fine. I've moved the code block into a code behind razor.cs file and now have this issue.

[jasonmalinowski]

@zeekbrown Is that all stitched together from a single file? Or different files?

[zeekbrown]

All screen shots were from the same file. It was too many lines to show easily so I took screen shots of the problem lines from within the file and stitched them together into a single screen shot.
