The docs are pretty clear
https://developer.chrome.com/docs/extensions/mv3/getstarted/
Once completed you zip up the folder for deployment.
You can setup a webpack project if you want to use angular, react or vue for the UI. Google for examples for your chosen framework.
Note: as you reference asp.net, I assume it will be a webapi called from the extension as no website is required to host the extension, it really is just static website hosted by the browser, installed in the extensions folder.
