Question

I created a C# class library using visual studio and it works well in visual studio, and when trying to execute it in mono develop I get error
the library code:

    namespace ClassLibrary2
{
    public class Class2
    {

      public  static void dosomething() {Console.WriteLine("dfss"); }
    }
}

the code in mono develop:

namespace cons
{
    class MainClass
    {
        public static void Main (string[] args)
        {

            ClassLibrary2.Class2.dosomething();
        }
    }
}

the error

Answer 1

What target framework (2.0, 3.5, 4.0) did you specify in VS?? It seems that your mono develop uses different (lower) version.
