@devhl-labs thanks for the suggestion. May I know if you've time to contribute a PR with the enhancement?

[devhl-labs]

I can give it a go. Do I do a pr for master, 5.0, or a new branch? In the issue I referenced there is a pr checklist, I don't understand the last bullet. Copy the technical committee. Sorry, copy what?

[wing328]

Please target the current master (5.0.0-snapshot)

Please copy (cc or tag) the C# technical committee stated in https://github.com/OpenAPITools/openapi-generator#62---openapi-generator-technical-committee to review the PR.

I'm running mvn clean install which appears to succeed, then from .\bin\windows & ".\typescript.bat to update the samples, but that gives me an error of The goal you specified requires a project to execute but there is no POM in this directory (E:\repos\openapi-generator\bin\windows). Please verify you invoked Maven from the correct directory. I'm not sure how to update the samples.
