Hello friends

I have created a class library in this directory:

E:\My Document\Uncompleted Project\Meysam

When I create another application, I will add the output of my library (Meysam.Library.dll) to the new application's references, from this directory:

E:\My Document\Uncompleted Project\Meysam\Meysam.Library\bin\Debug

The methods are not going to give me the correct output in new application.

It doesn't make sense, does it?

What can I check for fixing this?

For more info:
I call the below method in new application from my class library.

public static bool IsPrime(int number)
{
    if (number < 2) return false;

    if (number == 2) return true;

    for (int i = 2; i <= System.Math.Sqrt(number); i++)
       if (number % i == 0)
           return false;

    return true;
}
