Working out if a deserialize can deserialize an xml string

[ASB]

Grrr....

Need to try and figure out if a given XML serializer is capable of deserializing a given XML string. At this point I don't know what type it is expected to be.

CanDeserialize works fine - but not if the serialization assemblies are auto generated.

CanDeserialize does not work with generated assemblies using sgen.exe

Any suggestions ? The only thing I have available is some XML serializers and the XML string...
