Object reference error while including non pure mode dll

[rushi216]

I want to consume simple php library in c# application, for that I have simple php class like below,

class SampleObj
{
    public $Message = "Hello world!";

    function Write($arg)
    {
        echo $arg."\n";
    }

    function Add($a, $b)
    {
        return $a + $b;
    }
}

I am converting this into dll using below command

phpc /target:dll /out:objects.dll objects.php

Now i am using it in c# console application by below code

ScriptContext ctx = ScriptContext.CurrentContext;
ctx.Output = Console.Out;
ctx.Include("objects.php", false);

I have also added below in App.config file and gave reference to objects.dll in project references

<phpNet>
    <classLibrary>
      <add assembly="mscorlib"/>
      <!--<add assembly="objects, Version=1.0.0.0" />-->
      <add url="objects.dll" />
    </classLibrary>
</phpNet>

Still I am having exception like below

{"Library assembly 'file:///C:/CSharpConsole/bin/Debug/objects.dll' could not be loaded. Object reference not set to an instance of an object."}

What could be the issue?

Can you please debug it so we can see the full stacktrace?

@rushi216 Phalanger's development is mostly discontinued in favor of PeachPie, the more modern compiler and runtime that also targets .NET Core. Please feel free to give that a try.
