I would like to produce C# helper files from the KML2.2 xml schema using the XSD.exe tool (from VS2008 SDK). With KML2.1, the tool worked just fine. However, the KML2.2 schema contains import tags pointing to other schemas causing XSD.exe to freak out.
This is the error message I get:
C:\Program Files\Microsoft Visual Studio 2008 SDK\VisualStudioIntegration\Sample
s\Sdm> xsd.exe d:\temp\kml22.xsd /c /l:CS /n:Google.Kml22 /o:D:\temp\

Do you have suggestions how could I generate my C# helper files?
You have to specify all of the XSDs involved, including imports, in the command line. Here’s a blog post with an example.
