.net - 'Specify' Postfix on Properties of Auto-Generated Classes from Web Reference -

-

i need develop web services in .net 4.0, .net 2.0 clients can call services.

when create auto-generated proxy classes in visual studio 2010 using 'add web reference...' feature, there boolean properties 'specified' appended property name.

for example:

public long id { set; get; } public bool idspecified { set; get; }

why these properties added? , there can prevent them being added? or can ignore completely?

i think properties being generated wsdl.exe or svcutil.exe. exist in proxy classes, , not service, correct? unless you're concerned them being used, wouldn't be, wouldn't bother doing trying them.
