dotnet-format verify-no-changes throw error for AOT app API

Describe the bug

I'm using dotnet format --verify-no-changes to verify the code style. When I use it with an AOT WebApi, it throws an error about the MapGet usage

while it succeeds in publishing.

To Reproduce

It could be reproduced with an empty webapi aot project

Steps to reproduce

dotnet new webapiaot -n AotApi

cd ./AotApi

dotnet format --verify-no-changes

Exceptions (if any)

Error throws
