Thanks Jeroen, I did some more testing. I can call my

    public static int add(int one, int two) {
        return one + two;
    }

method in my class from my Windows 8 phone application and display the
result. However if I try anything more complex:

    public static int add(int one, int two) {
        WeakReference<Integer> oneRef = new WeakReference<>(one);
        WeakReference<Integer> twoRef = new WeakReference<>(two);
        return oneRef.get() + twoRef.get();
    }

or even something like concatenating strings:
    public static String add(String one, String two) {
        return one + two;
    }

I get

System.TypeLoadException was unhandled by user code

Googling around I found that ISerializable is not supported on the Windows
Phone platform:

The Windows phone does not support the whole of .NET framework, the list of
supported APIs are:
http://msdn.microsoft.com/en-us/library/jj207211%28v=vs.105%29.aspx

So, you get the error:
Could not load type 'System.Runtime.Serialization.ISerializable' from
assembly 'mscorlib, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=7cec85d7bea7798e'

The ISerializable and SerializationInfo are not present in Windows phone
.NET API.
The Namespace for Windows phone is:
http://msdn.microsoft.com/en-us/library/system.runtime.serialization(v=vs.105).aspx
For .NET framework is:
http://msdn.microsoft.com/en-us/library/System.Runtime.Serialization(v=vs.110).aspx

Naïve approach to use -noautoserialization as parameter to ikvmc.exe didn't
help. I guess I am stuck.

What would be your advice for my next step? Thanks.
