Comments
  • @jacerhea: No. class Program is internal, Main() is private.
  • Is "New console project template" a reference to Visual Studio? If so, it would be appropriate to add the 'visual-studio' tag.
  • @DavidRR Yes, it's a reference to VS, but it is irrelevant to the question though.
  • That also means you don't even have to call the main method "Main". The C# Compiler enforces that, but other .net languages can use whatever they want.
  • Even if the functionality of the console program should be callable directly by other assemblies, it is often a bad idea to open up Main. It is better design to expose a public Facade that external programs can call. Main handles command line arguments and then calls into the same Facade.
  • @Anders: Fair point, but we are just talking about feasibility, not design.
  • This should be the selected answer.
