If you are trying to compile the GroupWise WSDL and schemas on Microsoft .Net and get the following error: "Reference to a non-shared member requires an object reference", you need to change the generated .Net code directly. It appears to be a parsing error in .Net.

For example, change <System.Xml.Serialization.XmlIgnoreAttribute()> _
<Xml.Serialization.XmlIgnoreAttribute()> _

I removed the "System." at the beginning of the statement.

After I made the above changes, I was able to successfully compile.
