DataContractSerializer Case Sensitivity

I need to deserialize a raw xml to a particular object. However I am having issues when it comes to boolean and enum types, as case sensitivity is intact.

public MyObjectTypeDeserializeMethod(string rawXML)
{   
    DataContractSerializer serializer = new DataContractSerializer(typeof(MyObjectType));   
    MyObjectType tempMyObject = null;

    try
    {
        // Use Memory Stream
        using (MemoryStream memoryStream = new MemoryStream())
        {
            // Use Stream Writer
            using (StreamWriter streamWriter = new StreamWriter(memoryStream))
            {
                // Write and Flush
                streamWriter.Write(rawXML);
                streamWriter.Flush();

                // Read
                memoryStream.Position = 0;
                tempMyObject = (MyObjectType)serializer.ReadObject(memoryStream);
            }
        }
    }
    catch (Exception e)
    {
         throw e;
    }

    return tempMyObject;
}

public class MyObjectType
{
    public bool boolValue {get; set;}
    public MyEnumType enumValue {get; set;}
}

If the raw XML contains

<boolValue>true</boolValue>

it works fine. However it throws an exception whenever the value is different to the the previous, such as

<boolValue>True</boolValue>
