Don't overwrite a custom set HttpClientFactory

An end-user, or unit tests, should be able to set a custom

changed stream closing to scoped closing of stream reads
added .vs/ directory to gitignore

dot vs ignore correction

updated to correct notation for ignore of a directory in the root folder of repository
