data contract code generation for large/complex schema (HR-XML/OAGIS) - is there an alternative?

Posted By:      Posted Date: September 01, 2010    Points: 0   Category :WCF
Hello, and thank you for reading.I am implementing a Service based on a predefined specification (HR-XML 3.0). As such, I am starting with the schema, and working my way back to code. There are a number of large Schema documents (which import yet more Schema documents) related to my implementation, provided by this specification.I am able to generate code using xsd.exe, by supplying the "main" and "supporting" xsd files as arguments. But there are several issues, and I am wondering if this is the right approach.- there are litterally hundreds of classes - the code file is half a meg in size- duplicate classes (ex. Type, Type1 - which both represent the same type)- there are classes declared as inheriting from a base class, but that base class is not generated/definedI understand that there are limitations to the types of Schema supported by svcutil.exe/xsd.exe when targeting the DataContractSerializer and even XmlSerializer. My question is two-fold:1. Are code generation "issues" fairly common when dealing with larger, modular xsd files? Has anyone had success with generating data contracts from OAGIS or HR-XML schema?2. Given the above issues, are there better approaches to this task, avoiding generating code and working with concrete objects? Does it make better sence to read and compose a SOAP message directly, while sti

SvcUtil-generated code or shared interface/data contract assembly?

If you control both service and client is there any benefit in using svcutil.exe to generate client proxies? Or is it better to share interface/data contract assembly between client and service?

Data: More Load, Less Code with the Data Enhancements of ASP.NET 2.0


A data source control is a server control that wraps some basic functions of a data source - be it a SQL Server database, an XML document, an Excel worksheet, or a sitemap description. Through the services of a similar component, data-bound controls can fetch data as well as insert new records or update and delete existing ones. Data source controls enable a consistent model across a variety of data sources and dramatically reduce the amount of code needed to implement a two-way data-binding scenario. This article provides an introduction to data source controls and other related data binding features.
