Per repo guidelines, titles use sentence case. First word and proper nouns capitalized. In this case startup is not a proper noun.

Good catch, multiple YARPS! That awful we had that in there. Minor fix: Sentence case for titles.

"imlemenation implements" sounds goofy. Alhtough technicaly correct if I squint, it needed an improvment certtainly. Changing to "instance implements" is technically incorrect, since instances don't implement interfaces, classes do. See what you think of my suggestion above.

Also a minor item fixed: missing space added after a bracket.

 The following app startup code supports several app types:

+* [Blazor web apps](xref:blazor/index#build-a-full-stack-web-app-with-blazor)


Suggested change

Proper noun here I think.
