Create class at runtime, serilize and de-serilize then cast to Interface froblem - class

Question

Hi,
I have the following code :
public static object CreateTypedReport(string typeName, string inheritFrom)
{
DirectoryInfo dirInfo;
CSharpCodeProvider c = new CSharpCodeProvider();
CompilerParameters cp = new CompilerParameters();
foreach (Assembly asm in System.AppDomain.CurrentDomain.GetAssemblies())
{
if(!asm.FullName.StartsWith("ReportAssembly, Version=0.0.0.0"))
cp.ReferencedAssemblies.Add(asm.Location);
}
cp.CompilerOptions = "/t:library";
cp.GenerateInMemory = true;
dirInfo = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\MyApp\\ReportAssemblies\\");
if (!dirInfo.Exists)
dirInfo.Create();
cp.OutputAssembly = dirInfo.FullName + typeName + "Assembly";
cp.ReferencedAssemblies.Add(typeof(XtraReport).Assembly.Location);
//cp.OutputAssembly = typeName + "Assembly";
StringBuilder sb = new StringBuilder("");
sb.Append("using System;\n");
sb.Append("using MyNamespace.UI;\n");
sb.Append("namespace TypedReports { \n");
sb.Append("public class " + typeName + " : " + inheritFrom + "{ \n");
sb.Append("} \n");
sb.Append("}\n");
CompilerResults cr = c.CompileAssemblyFromSource(cp, sb.ToString());
if (cr.Errors.Count > 0)
{
MessageBox.Show("ERROR: " + cr.Errors[0].ErrorText, "Error evaluating cs code", MessageBoxButtons.OK, MessageBoxIcon.Error);
return null;
}
return cr.CompiledAssembly.CreateInstance("TypedReports." + typeName);
}
This will create a class based on the typeName and inheritFrom parameters and then finally an object will be created and returned. inheritFrom will point at a class that implements IMyInterface.
It's possible to cast this object to a IMyInterface if it's needed.
When we then serialize and de-serialize this object we will not be able to cast it to IMyInterface anymore?
Why? And how could I solve it?

The problem was in the serialization och deserialization of the object. When this was changed it worked great. The solution is in a third party product so I can´t post it here.
