Program.Main(string[])' has the wrong signature to be an entry point Format For Project

Question

I have a warning and an error in Microsoft Visual studio 2019. Everything was working just fine and this seemed to pop up out of no where.

Main is defined as:

 static object Main(string[] args)

But I am getting this whilst trying to compile:

Warning CS0028 'Program.Main(string[])' has the wrong signature to be an entry point Format For Project

Error CS5001 Program does not contain a static 'Main' method suitable for an entry point Format For Project

Answer 1

There are a number of possible signatures for the entry point in to a C# program. Unfortunately static object Main(string[] args) is not one of them.

I'd say your most likely candidate is either

static int Main(string[] args)

Or

static void Main(string[] args)
