[Mono-dev] GUIDs in a web service

[Joe Dluzen]

Hi all,

I'm having trouble with GUID parameters in a web service. Error:
XmlSchema error: Referenced schema type http://www.example.com/:guid
was not found in the corresponding schema. Related schema item
SourceUri: , Line 0, Position 0.

Stack trace:

System.Xml.Schema.XmlSchemaException: XmlSchema error: Referenced
schema type http://www.example.com/:guid was not found in the
corresponding schema. Related schema item SourceUri: , Line 0,
Position 0.

>From searching around, it seems that GUID is not a build in type, but
a schema possibly existed at one point in time at
http://microsoft.com/wsdl/types.

I've found http://lists.ximian.com/pipermail/mono-devel-list/2005-November/015981.html
which seems to be related.

I'm now attempting
http://msdn.microsoft.com/en-us/magazine/cc164115.aspx#S7 to see if
that will help, but I'm really hoping that there's an easier way.

I'm on XP with Mono 2.4 and XSP.
Ubuntu 8.10 Mono 2.4.

Thanks,
