ArgumentException on PropertyInfo.SetValue() in .Net Compact

I am using DapperLite, a port of Dapper, for use in Compact Framework. I get an ArgumentException, no other info in the below method at the specified line of the SqlMapper.cs file.

Really struggling with what to look for next or what's actually broken.

/// <summary>
    /// Populate a references type from an IDataRecord by matching column names to property names.
    /// </summary>
    private static void PopulateClass(object objectClass, IDataRecord reader)
    {
        Type theType = objectClass.GetType();
        PropertyInfo[] p = theType.GetProperties();


        // Only set properties which match column names in the result.
        foreach (string columnName in GetColumnNames(reader))
        {
            string colName = columnName;
            object value = reader[colName];
            PropertyInfo pi = p.FirstOrDefault(x => x.Name == colName);


            if (pi == null || value == DBNull.Value) continue;


            Type columnType = value.GetType();
            Type actualType = Nullable.GetUnderlyingType(pi.PropertyType) ?? pi.PropertyType;


            // Check for a directly assignable type
            if (actualType == columnType || actualType == typeof(string) || actualType == typeof(int))
            {
                // Error generated here
                pi.SetValue(objectClass, value, null);
            }
            else
            {
                value = actualType.GetMethod("Parse", new[] { typeof(string) }).Invoke(null, new[] { value });
                pi.SetValue(objectClass, value, null);
            }
        }
    }

The values at that point are objectClass = Models.Employee and value=1. The colName, from further up in the Method, is Id which is an int in the Employee model.

Added Employee Model based on Comment:

namespace BioPadPunchClock.Models
{
    public class Employee
    {
        public int Id { get; set; }
        public int CDB_Employee_PK { get; set; }  //Employee PK in the Central DB. If .null., new emp record on this timeclock needs to be pushed to the CDB.
        public string Name { get; set; }
        //public string FaceImage { get; set; }  //path to Jpeg image 136x90 pixels .\NAND\pictures\  named as <pk>.jpg
        public DateTime? BirthDate { get; set; }
        public string Status { get; set; }  //Full Time – Hourly, Inactive, Terminated, Part Time - Hourly  
        public DateTime? LastPunch { get; set; }
        public string LastPunchDirection { get; set; }  //IN or OUT
        public string PIN { get; set; }  // 4 digit
        public int CardNum { get; set; }  //HID Card Number
        public int CardFacCode { get; set; }  //HID Card Facility Code
        public string FpTemplate { get; set; }  //Fingerprint Template (registered fingerprint)
        public DateTime? LastUpdate { get; set; }  //When this employee record was last sync’d to the CDB. This value will match exactly in the LDB and CDB after a successful sync.
        public int DayTotal { get; set; } // Minutes cumulative for the current day at time of last punch
        public int PayPeriodTotal { get; set; } //Minutes cumulative for the current pay period at time of last punch
        public string Department { get; set; }
        public string SSN { get; set; }
        public bool ShouldPromptDept { get; set; } //Prompt employee to choose department each time
    }
}

Further findings...

When I look at my Model.Employee at that point all of the string properties say Could not evaluate expression with a red exclamation point. Is this a clue or normal?

Further findings...

Not sure if this matters or not but when I step through the code and inspect the values I notice that the actualType == Int32 and the columnType==Int64 while the value it's evaluating is 1.

Not sure that makes any difference since there is a actualType.Equals(typeof(int)) but figured I'd mention it.
