If you need to rename the 'AppDomain.CurrentDomain.GetAssemblies()' for testing, here is something you can try:
public static void RenameCurrentDomainAssemblies()
{
foreach (var a in AppDomain.CurrentDomain.GetAssemblies().Where(a => a.FullName.StartsWith("System")))
{
FieldInfo fullName = a.GetType().GetField("m_fullname", BindingFlags.Instance | BindingFlags.NonPublic);
fullName.SetValue(a, "Gotcha");
}
AppDomain.CurrentDomain.GetAssemblies().Where(a => a.FullName.StartsWith("SyS")).Dump();
}
