Bug? : Sgen breaks web-service serialization

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :.NET Framework
I am using the noaa weather web service and it works fine if I have not run sgen on the assembly. I have sgen disabled in the project settings and instead run it explicitly in the main build. I run sgen using the command: sgen /a:myassembly.dll /force /compiler:/keyfile:myassembly.snkThis creates an [assembly_name].XmlSerializers.dll and when running the application again, the same call to the web-service fails with the following exception. This is internal to the web-service code so I'm stuck for what to do other than not run sgen:System.InvalidOperationException: There was an error generating the XML document. ---> System.ArgumentException: Item has already been added. Key in dictionary: 'myassembly.gov.weather.www.productType' Key being added: 'myassembly.gov.weather.www.productType' at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add) at System.Collections.Hashtable.Add(Object key, Object value) at System.Xml.Serialization.XmlSerializationWriter.AddWriteCallback(Type type, String typeName, String typeNs, XmlSerializationWriteCallback callback) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.InitCallbacks() at System.Xml.Serialization.XmlSerializationWriter.GetTypeEntry(Type t) at System.Xml.Serialization.XmlSerializationWriter.WriteReferencedElement(String name, String ns, Object o, Type ambientType)

RIA Service Serialization of POCOs

Hi, I have an object graph that I'm trying to persist while it's in an interim state.  I don't want to put the data in the true tables, so I'm serializing the graph and storing it in a separate table.  I'm using WCF/RIA services (v.1.0) to link my Silverlight (v.4) client with my back-end server (.NET v.4 with Entity Framework).  I'm using POCOs instead of entities on the back-end. I was able to decorate all of the members of my object graph with the [DataMember] attribute as well as decorate the classes with [DataContract].  When these POCOs are copied to the client project the [DataMember] attributes are missing from the child collections.  So when I serialize the graph (on the client) the children are missing.  I have also tried to send the graph to the server and serialize it there, but the children are missing when the graph gets to the service method.  On a side-note, persisting the graph into its set of tables works fine. I've tried this from numerous angles and cannot figure out how to get this working.  Any suggestions or alternatives would be greatly appreciated.  

.net 4.0 breaks serialization test - MemoryStream that cannot seek



I'm serializing a Dictionary<string,string> using BinaryFormatter to a class that extends MemorySteam that I call CannotSeekStream (source below).  CannotSeekStream follows the MSDN guidlines for throwing NotSupportedException from a few properties/methods.  In .net 3.5 I can serialize just fine.  In 4.0, I get a NotSupportedException from the Length property.  stacktrace is below.  At a high level, its strange that I cannot serialize to a stream that cannot seek.  Is this a bug in the framework?

Windows Service Applications Tutorials

You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

WCF Tip: Using Properties in Service Contracts

you'll notice all of the Service Contracts are implemented with interfaces containing only methods. For the longest time I thought that's all that was supported, until I thought about it a little more. In C# land, properties are simply wrappers around a get method and set method, so why wouldn't we be able to use properties in a service contract? Well the answer is we can.

Realizing a Service-Oriented Architecture with .NET

This article is meant to be a practical discussion guide to building a .NET application in a service-oriented architecture. We will consider real-world goals, real-world obstacles, and experience-based solutions. I quickly concede the approaches discussed here are not exhaustive or infallible. This paper is focused on application development, not application integration. We will specifically consider architectural issues and component design issues.

The Potential of Web Services

Web Service for uploading documents into SharePoint

WS UploadService is a web service written for Microsoft Office SharePoint Server 2007 and Windows SharePoint Services 3.0 and is meant for uploading documents into SharePoint. I have just uploaded the zip file to GotDotNet.com so it will take some time before the zip file appears in the list of downloads. For the time being, you can download the zip file from the following location

Creating and Using an ASP.NET Web Service in Visual Web Developer

In addition to letting you create Web pages, Microsoft Visual Studio also lets you create Web services that use ASP.NET XML. Creating a Web service in Visual Studio is similar to creating a Web page. You can also use the Microsoft Visual Web Developer Web development tool to reference and use Web services that are in a Visual Web Developer solution, on your local computer or in a local or external UDDI directory. In this walkthrough, you will create the Web service in one solution and use it in another.

Tasks illustrated in this walkthrough include:

Creating a simple XML Web service in Visual Web Developer.

AutoGenerateSelectButton="False" ignored when using Domain Service


Crosspost from RIA Services forum: http://forums.silverlight.net/forums/t/196466.aspx

I'm creating a Dynamic Data application in VS2010 and have recently switched to using a Domain Service to give greater control over the data presented to the client. I've noticed that the AutoGenerate<Action>Button attributes on my GridView are being ignored. The presence of the Edit and Delete buttons appear to be contingent on the existence of Update and Delete methods on the partial classes autogenerated in the Domain Service, but i'm not seeing how to control the generation of the Select button. Is there a way to control this from within the Domain Service class?

Any framework for creating a job scheduler service?


Just curious to know if there was any official Microsoft code blocks, classes, or such for writing a service that runs other assemblies or WCF services?  That can be configured easily from a web page, pre-coded, for running tasks at certain times on certain recurring intervals?  I've already built one but am open to anything done better- which I'm sure there is.  Thanks!!!

Problem to obtain client IP on web service



I'm having problems to obtain the client IP on web service. Here's my scenario:

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP and host name ServerTransaction.
Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on  ServerTransaction, with IP and host name ServerApplication.
Many other computers on the local network (IPs:,,, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (

Any idea or tip?

Thanks and sorry for my bad english.

A lengthy operation in an ASP.NET web service


I've built an ASP.NET web service with .NET 2.0 (an asmx file). I invoke a web service method using Ajax. The method takes a substantial amount of time to execute (5 minutes to 1 hour). I believe it's not a good idea to "hang" the web request for so long.
I'm wondering if the web service method could spawn an additional process which in turn would execute the lengthy operation and notify the web service once the operation is completed.
Are there any good practices regarding this kind of functionality?


.Net Frameword 4 SOAP Web Service



We want to upgrade from VS2005 to VS2010. Before we do that, I would like some clarity about some things.


Can we build typical SOAP webservices with the 4 Framework as I could with 2.0?


Would a WCF Service allow me to have both REST/SOAP services in one application?


Is Framework 4 ONLY for REST services and I need to stick to 3.5 for SOAP?


I downloaded the free Web Developer 2010, but I cannot seem to get anywhere trying to figure this out.


Thanks for any input.





problem compiling web service


Using Visual Studio 2010.

I created a webservice GetDemographicData asmx, GetDemographicData asmx.cs and then used wsdl to create a proxy, then used csc.exe to create dll.

first time when I generate proxy, it looks and works fine, but when I make some changes to my webservice and regenerate proxy the following problems occur:

1.I lost the function: public DataSet Get_GetDemographicData(string CaseNum, int Version)
2. The namespace changed to my-labs

Why?? Please see my code below:
