There is a small bug in .NET 3.0 WCF proxy generation tool:

Using an .asmx web service with a method like

[WebMethod]
[return: XmlAttribute]
public string HelloWorld(int a, [XmlAttribute]int b, int c)

svcutil /serializer:Auto or the AddServiceReference feature in Visual Studio generates a

public void HelloWorld(int a, int c)

proxy method - without any complain or warning. Using svcutil /ser:XmlSerializer works. See this MSDN forum thread.

Addendum: This bug is NOT fixed in .NET 3.5.
