I have WebService that returns
XmlDocument. I made that XmlDocument from DataSet, but when DataSet is empty
I get error:

System.InvalidOperationException: There was an error generating the XML
document. ---> System.NullReferenceException: Object reference not set to an
instance of an object...so how I can avoid this error?

Thanks for reporting the problem.
It'll be nice if you provide a small repro for this bug.
DataSet class doesn't have direct method that creates XmlDocument from it
and error can depend on how you doing this.
