How can I create Debian install packages in Windows for a Visual Studio project?
Debian's .deb packages are just "ar" archives containing tarballs. You can manipulate both types of files using cygwin or msys quite easily:
$ ar xv asciidoc_8.2.1-2_all.deb x - debian-binaryx - control.tar.gzx - data.tar.gz$ tar -tzf control.tar.gz ././conffiles./md5sums./controlOr you can install all the "standard" Debian stuff using cygwin, I suppose, but most of that stuff won't benefit you much if you're building a .Net app anyway.
If you use the .NET Core SDK, you can use dotnet-packaging tools to create a Debian installer package from any platform that runs .NET Core.
For example, running dotnet deb -c Release -f netcoreapp2.1 -r ubuntu.16.04-x64 would then create a .deb file which you can use to install your app on Ubuntu 16.04.
The project repository has more details.
I am not aware of any plugin that does it natively, especially since Mono users seem to prefer MonoDevelop.
However, it should be possible to use Cygwin and a custom MSBuild Task or Batch file in order to achieve that by using the native .deb creation tools.
