EPC Tag Decoding problem
- We were using the following code to do SGTIN Decoding to extract the Item Reference of an Item.
byte[] byteArray = HexUtilities.HexDecode(tagId);string itemReference = string.Empty;
string companyPrefix = string.Empty;
string serialNumber = string.Empty;
if (IdentityEncoding.TryParse(byteArray, out ie))
{
if (ie.GetType() == typeof(Sgtin96Encoding))
{
Sgtin96Encoding sgtinEncoding = (Sgtin96Encoding)ie;
itemReference = sgtinEncoding.ItemReference;
companyPrefix = sgtinEncoding.CompanyPrefix;
serialNumber = sgtinEncoding.SerialNumber;
}
}
It worked great till yesterday but from today onwards, this has stopped working (The parsing fails if byte array is passed). It works fine if I use URN encoded string ("urn:epc:tag
gtin-96:0.0652642.000031.1000") but fails if I use the byte array. Can anyone help me in this regards? It seems that today's windows update created this problem.

Can you give the error details?
- There is no error. The output variable to the Try Parse method (ie) simply returns as NULL. The IdentityEncoding.TryParse method is not able to parse the SGTIN encoded hex string "301427D5880007C0000003E8", which I encoded using the following code:
Sgtin96Encoding encoding = new Sgtin96Encoding(Sgtin96FilterValues.AllOthers, "0652642", "000031", "1000");
string tagId = encoding.ToHexString();
This works fine if instead of Byte Array, I pass in the URN encoded string ("urn:epc:taggtin-96:0.0652642.000031.1000") The data seems fine. Can you try using IdentityEncoding.Parse instead of TryParse and see what exception is thrown?
- The following error is returned on using Parse method:

It seems to indicate that the BizTalk RFID is expired but that's not the case. I am trying to find the latest versions of Microsoft.Rfid.ObjectModelExtensions.dll, which is not available with the BizTalk RFID installed. May be the version I have (Assembly Version - 3.7.0.0) has expired.
Any clues? Looks like you have the CTP version which has expired. You should get the Beta bits.
Please use the Beta drop from

Looks like you are using our CTP bits, which has expired.
