I use this function to serialize in xml file a collection of object.

    public void SerializeEnvironment()
    {            
            if (xs == null) xs = new XmlSerializer(typeof(IList<Classes.Environment>));

            using (StreamWriter wr = new StreamWriter(ConfigFilePath))
                xs.Serialize(wr, Environments);            
    }

The program works perfectly on my dev machine. But when i make deployment on other computers, the program failed on the serialization method with this error :

System.InvalidCastException: [A]System.Collections.Generic.List1[Product] cannot be cast to [B]System.Collections.Generic.List1[Product]. Type A originates from 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' in the context 'LoadNeither' at location 'C:\Windows\Microsoft.Net\assembly\GAC_32\mscorlib\v4.0_4.0.0.0__b77a5c561934e089\mscorlib.dll'.

I test many things to resolve but without success. Thanks in advance for any suggestions or resolution :)

In addition, here my object class :

[Serializable]  
public class Environment
{
    public string name { get; set; }
    public string value { get; set; }
    public Environment(){}
    public Environment(string Name, string Value)
    {
        name = Name;
        value = Value;
    }
}
