I am new to .NET CORE but I have followed a few tutorials. The tutorials I have followed are basically "Hello World" types of programs where I make a small functional .Net Core application and I publish it. They are basically a DLL, I assume, and they run in some sort of system/container where they can run on any OS. Even though the final product is a DLL, the code itself seems to be structured in a way where it is an actual executable application.
So how would I translate an actual C# DLL project into a .NET Core project? How would a project that is already designed to produce a DLL work in a .Net Core project?
Executables only have one entry point: static void Main.
.NET Libraries expose public methods which are all entry points in that sense.
An "entry point" in a program is where the operating system invokes an executable program file, the term does not apply to libraries. (and ASP.NET web-application files are really just libraries, the ASP.NET host just looks for certain exposed Page/Handler/Controller types). This applies to ASP.NET. Does it also apply to .NET Core? Also, when I ran my .NET Core applications, I did it from a special command line. So how would that work if I translated a DLL C# program into a .NET Core program?
You cannot have multiple entry points in an executable program. The nearest would be to pass command line switches that alter how the program runs.
DLL files can have entry points, and they can be run using rundll32. Some can be accessed using vbscript as well. (at least, on 32-bit.)
As long as you know the "hook". But most (for my experience) recognize few hooks. Not much or any help - just my experience with trying to run "exposed" subroutines of DLL files.
OVER to someone who knows a lot more than I do...
