Would like to compile a basic program with a reference to a dll in C#

I would like to compile a simple console application which uses a reference from a .dll to learn how basic dynamic linking in csharp works. The main file is test.cs:

using System;
using TestLibrary;

namespace Test
{
    class Test
    {
        static int Main()
        {
            Console.WriteLine(TestLibrary.AddThreeNumbers(1,2,3));
            return 0;
        }
  
    }

}

The class library is:

using System;

namespace TestLibrary
{
    class TestLibrary
    {
        int AddThreeNumbers(int a, int b, int c)
        {
            return a+b+c;
        }
  
    }

}

I use the following in the powershell developer command prompt to compile library.cs into a dll:

csc library.cs -target:library -out:library.dll

This works fine. But I then try to link to make an executable as follows:

csc test.cs -reference:TestLibrary=library.dll

But this returns an error:

test.cs(2,7): error CS0246: The type or namespace name 'TestLibrary' could not be found (are you missing a using directive or an assembly reference?)

Is this is a problem with my code or a problem with how I am compiling it? Any help would be much appreciated.

As @Gusman said the command to use is :

csc /r:library.dll /out:test.exe test.cs
