Наконец-то у меня все заработало.Следующие методы расширения типа возвращают точно такой же результат, что и реализация .NET 4.0, но без исключений MethodAccess, генерируемых WP7:
public static class TypeExtensions
{
public static MethodInfo GetMethodWp7Workaround(this Type type, string name)
{
if (name == null)
{
throw new ArgumentNullException("name");
}

}
public static MethodInfo GetMethodWp7Workaround(this Type type, string name, Type[] types)
{

{
throw new ArgumentNullException("name");
}
if (types == null)
{

}
if (types.Any(t => t == null))
{

}
return GetMethod(type, name, BindingFlags.Public | BindingFlags.Static | BindingFlags.Instance, null, CallingConventions.Any, types, null);
}
public static MethodInfo GetMethodWp7Workaround(this Type type, string name, BindingFlags bindingAttr)

}
Вы получите тот же результат для следующего класса с .NET 4.0, и этоОбходной путь на WP7:
