✅ namespaces

every time i try to use namespace and class i get Error CS5001 Program does not contain a static 'Main' method suitable for an entry point what am i supposed to do because

namespace helloword
{
    class HelloWorld
    {

    }
}

namespace helloword
{
    class HelloWorld
    {

    }
}

gives the same error as

namespace helloword
{
    class HelloWorld
    {
        static void Main()
        {

        }
    }
}

namespace helloword
{
    class HelloWorld
    {
        static void Main()
        {

        }
    }
}

Anton•16mo ago

just asking for more context $main

$mains

$mains

The possible signatures for Main are

public static void Main() { }
public static int Main() { }
public static void Main(string[] args) { }
public static int Main(string[] args) { }
public static async Task Main() { }
public static async Task<int> Main() { }
public static async Task Main(string[] args) { }
public static async Task<int> Main(string[] args) { }

public static void Main() { }
public static int Main() { }
public static void Main(string[] args) { }
public static int Main(string[] args) { }
public static async Task Main() { }
public static async Task<int> Main() { }
public static async Task Main(string[] args) { }
public static async Task<int> Main(string[] args) { }

public is not required (can be any accessibility). Top-level statements are compiled into a Main method and will use an appropriate signature depending on whether args is referenced, the await operator is used and/or an explicit return statement is used. https://docs.microsoft.com/en-US/dotnet/csharp/fundamentals/program-structure/main-command-line

Main() and command-line arguments

Learn about Main() and command-line arguments. The 'Main' method is the entry point of an executable program.

maybe they want it to be public now?

Elmishh•16mo ago

nope tried that too same thing

Anton•16mo ago

well you might be mistaken somewhere, maybe you're running a different project

Elmishh•16mo ago

wdym

Anton•16mo ago

maybe someone is trolling you by messing with the msbuild sdk the namespace should not affect this

Elmishh•16mo ago

might be the class its the class class isnt working

class Program
{
    public static void Main()
    {

    }
}

class Program
{
    public static void Main()
    {

    }
}

gives the same error im confused now

Elmishh•16mo ago
