FIX: On a computer that has the .NET Framework 3.5 Service Pack 1 installed, an exception is thrown when an application calls the GetOptionalCustomModifiers method or the GetRequiredCustomModifiers method on a ParameterInfo object of a generic interface

using System;
namespace GetCustomModifiersBug
{
    public interface IGenericInterface<T1, T2>
    {
        void GenericIfcMethod<T3>(T3 t3);
    }
    class Program
    {
        static void Main()
        {
            
                Type ifc = typeof(IGenericInterface<int, int>);
                // Either of the following lines on their own will cause the problem
                ifc.GetMethod("GenericIfcMethod").GetParameters()[0].GetOptionalCustomModifiers();
                ifc.GetMethod("GenericIfcMethod").GetParameters()[0].GetRequiredCustomModifiers();
                       
        }
    }
}
