Load compiled assemblies on scripts

[duddo]

Hi!
I'm trying to load into the evaluator an Assembly produced by CompileAssemblyFromFile, but I can't use the referenced type inside the script. Maybe I'm using a wrong syntaxis?
I put together a simpe example to explain what I'm trying to achieve.

Summer.cs:

using System;

class Summer
{
public int Sum(int a, int b)
{
return a + b;
}
}

Script.cs:

using System;

class Script
{
public int Execute()
{
Summer s = new Summer();
return s.Sum(10, 5);
}
}

Program.cs:

using CSScriptLib;
using System;

namespace CsScript
{
class Program
{
static void Main(string[] _)
{
CSScript.Evaluator.Reset(false); //clear all referenced assemblies

        //compile dll
        string referencedAssemblyName = CSScript.Evaluator.CompileAssemblyFromFile(@".\Summer.cs", @".\Summer.dll");

        //load dll
        CSScript.Evaluator.ReferenceAssembly(referencedAssemblyName);

        //execute
        dynamic script = CSScript.Evaluator.LoadFile(@".\Script.cs");
        int result = script.Execute();
        
        Console.WriteLine(result);
    }
}

}

Thank you!

You can. You only need to make your class Summer public.
. . .
As a side note please use https://github.com/oleg-shilo/cs-script repository. This one is no longer active.

Sorry for the wrong repo, should I reopen the question in the other one?

Unfortunately, even making the class public, I still get a compile error: it can't found the symbol.

I'm trying to use this approach as a workaround Roslyn, to try and have my script in separate files. Do you have any advise against this approach?
Thank you.
