I've not yet looked into the AOP features of .NET 3.5 but I've been on teams that used Spring.NET in the past (although I wasn't involved so I don't have any practical experience with it) I just found a pretty sweet article right here on CodeProject that rates some open source AOP add-ons. This might help you if you're really set on using it. Rating of Open Source AOP Frameworks in .Net[^] Good luck. ~j

Google "Aspect Oriented Programming (AOP)" and be prepared to read a lot... Glad you asked though because I didn't know this:

.NET 3.5 supports Aspect Oriented concepts through the Unity container.

Start here maybe: http://en.wikipedia.org/wiki/Aspect-Oriented\_Software\_Development

WCF is supposed to be much more compliant with standards than webservices but I have no experience with java and couldn't tell you definitely. What I do know is that a developer writing a WCF service can certainly make it so that it would NOT work with java. Meaning because it's WCF doesn't automatically make it consumable from java. I am currently writing a WCF service and have gone to great lengths to make it as vanilla as possible for that reason ... I would be interested in trying this with you. I could write a very simple service and see if you can consume it. But again.. I wouldn't be able to help on the java side of things at all. ~j

I've googled this to the point of absolute frustration without success, but it's what I would consider a noob question I'm hoping someone can help me with. There has been a lot of close-but-not-quite conversation on the interwebs about my issue so I'm going to be as explicit as I can (aka verbose ... sorry). My goal is to use svcutil to generate my datacontracts which are also my DTO's for my WCF service. Everything works great until i have a datacontract that contains another datacontract ... and it does work ... except I have to manually go into the referencing generated class and remove the duplicated definition ... EVERYTIME I regenerate. I thought the svcutil /excludetype (/et) option would do this but I can't get it to work. Here is an illustration: I have an .xsd file that looks like this: (I'm leaving out the headers removing all but a single property to keep it simple. In reality there is obviously a lot more to this than a phone number.)

<xs:complexType name="ContactDTO">
xs:sequence
<xs:element minOccurs="0" maxOccurs="1" name="PhoneNumber" type="xs:string" />
xs:sequence
xs:complexType

I run it through svcutil and it generates my datacontract perfectly and I get a ContactDTO.vb class. But then I have another xsd that references the first like so: (again.. greatly simplified to not waste your time)

<xs:include schemaLocation="ContactDTO.xsd"/>

<xs:complexType name="CustomerDTO">
xs:sequence
<xs:element minOccurs="0" maxOccurs="1" name="CustomerName" type="xs:string" />
<xs:element minOccurs="0" maxOccurs="1" name="Contact" type="ContactDTO" />
xs:sequence
xs:complexType

After a bunch of trail and variation I've landed on using the following command line to generate the classes:

svcutil /dconly ./CustomerDTO.xsd /n:http://mynamespacegoeshere.ccc/Schemas, /out:./Classes/CustomerDTO.vb /language:VB ./ContactDTO.xsd /et:ContactDTO.xsd

And like i said, it does work ... but I get two classes, the CustomerDTO.vb class which I want and ANOTHER copy of the ContactDTO.vb class that has already been generated previously and i have to go into my generated classes and hand edit the duplicates out. Now I could just not generate the first class however the point is resuse ... so I have several OTHER classes that reference ContactDTO and I have to edit out every instance of the duplicate generated cod
