Routes is unknown tag

[ilajosmanov]

Type: Bug

Issue Description

Blazor application with predefined files, Routes tag is not visible for the extention.

Steps to Reproduce

1. Create new BlazorApp.
2. Go to App.razor
3. See the error: Found markup element with unexpected name 'Routes'. If this is intended to be a component, add a @using directive for its namespace.Razor(RZ10012)

Expected Behavior

I shouldn't see this error, because <Routes /> is predefined component in Blazor ecosystem.

Actual Behavior

I see warning.
