C# - Check Compile Time That Type Is Marked With The Serializable Attribute?

Specifically we're making our application compatible with the Out Of Process Session State server where all types saved in session must be serializable. Is there a way to see at compile time that any type put into HttpSessionState is marked with the Serializable attribute. Something along the lines of this 'non-valid' code

public static void Put<T>( string key, T value ) where T : IsMarkedWitheSerializableAttribute
{
HttpContext.Current.Session[key] = value;
}
