Question

I am facing this issue in NX OPEN

Library is missing required entry point

Function Name: Main

I tried creating class library with framework .NET 8.0, 7.0 & 6.0.

In all frameworks, I am facing the same issue. How to fix this?

It seems that you tried to use the .NET 6.0, .NET 7.0 or.NET 8.0.

Siemens NX and NXOpen does only support .NET Framework. You need to create a ".NET Framework" class library in order to make it work. In my case, I used .NET Framework 4.7.2:

using NXOpen;

namespace NxOpenDemo
{
    public class Class1
    {
        public static void Main(string[] args)
        {
            Session theSession = Session.GetSession();

            theSession.ListingWindow.Open();
            theSession.ListingWindow.WriteFullline("Hello World!");
        }
    }
}
