This PR looks good to me. I'd like more recent .Net support as well without the warnings mentioned in issue #13. Based on PR #14, the original author was trying to migrate to github actions for Continuous Integration (CI) but isn't able to give as much attention to this project anymore.

@tqk2811 I notice that you have another branch that is a start on a nuget package. It didn't appear that it used a CI of any kind but is that something you know how to add? In any case, is your nuget package something you can publish for public consumption?

Yes, my private package for self use.

Great! Are you open to allowing this package to be public?

Along those lines, how about maintaining/releasing your forked version?

Link nuget you can install it, private for disable search only
And for my repo, you can do anything (under SpicyTaco license)
