Xarzu Posted April 11, 2018 Posted April 11, 2018 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?
Fenixp Posted April 13, 2018 Posted April 13, 2018 (edited) If you want to generate an executable, you do: dotnet publish -c Release -r win10-x64 "r" means "runtime", here's a list. By default, .NET Core compiles into a .dll which can then be executed on any platform supported by .NET Core (via dotnet "appname") You can't have multiple entry points into an executable application. Even web applications contain a Main which builds web host. Edit: Incidentally, https://stackoverflow.com Edited April 13, 2018 by Fenixp
