Strange Deserialization Error

So, I'm trying to deserialize a .NET object inside a CLR procedure; I've used SGEN to make an "xmlserialization" version of the object library, and registered it and the original assembly in SQL Server and referenced them from my CLR Procedure project.

Now, I receive the object as an XML Document and I'm trying to use XMLSerializer to deserialize the XML back into my object. If I try to specify the XMLRoot when I declare the XMLSerializer and deploy it SQL gives me the (in)famous can't use dynamically created assemblies error.

I could really use any help/inspiration/assistance!!

Here's most of the code:

Dim myCaseType As CaseMessageType = CType(myRead.ReadContentAsInt(), CaseMessageType)
SqlContext.Pipe.Send("Case Type=" & myCaseType.ToString())
Dim myXmlRoot As New XmlRootAttribute(CaseMessageElement) myXmlRoot.Namespace = CaseMessageSchema
SqlContext.Pipe.Send("Getting the type of the message") Dim myType As System.Type = GetCaseMessageSystemType(myCaseType)


SqlContext.Pipe.Send("Cretating xml serilizer object"

)
'this "works" but it won't deserialize
Dim xmlSerializer As New XmlSerializer(myType)
'this doesn't work, it gives me the error
'Dim xmlSerializer As New XmlSerializer(myType, myXmlRoot)
SqlContext.Pipe.Send("Deserialize the message")
myCase =

DirectCast(xmlSerializer.Deserialize(myRead), CaseMessage)
