WCF Memory Issues and Debug Diag

christinemfer — Fri, 18 Dec 2009 16:10:49 GMT

I have a wcf service that ocassionally starts consuming 500mb of memory. When this happens all requests to the service receive time out errors. I've captured a memory dump using Debug Diag but when I attempt to open/analyze the dump I receive the following error. Could not open specified dump file. Is the dump file corrupt? Also, any recommendations for helping me diagnose the issue would be greatly appreciated.

How to name a web service

duckkiller53 — Mon, 14 Dec 2009 16:37:35 GMT

Could someone help I am learning about Web Services and the following question came up with the book I'm reading.

Is my understanding of how you consume a web service correct. First you would create a web service and give it a unique namespace url. ie: <WebService(Namespace:="http://www.MyWebService.com/customers", Name:="MyCustomers")> _ If I understand this correctly this is what is used to locate the web service when adding referance to it in a client project. ( my book is not clear on this ). What really confused me is I had to add the project name to the url to actually add referance to the web service on my local machine. like this "http://localhost:52207/WEbServiceSample/Customers.asmx?wsdl". Note: WebServiceSample is the name of the project that I created the web service in. Obvioulsy I'm confused.

Thanks

Dave.

Response:

WSE Web Service and WSDL

HammadHaneefPasha — Thu, 17 Dec 2009 10:02:27 GMT

Hi,

My client has given me the URL of a web service that uses WS-Security of WSE 3.0. In the documentation provided I have been told to install and configure WSE3.0 on the development environment and use WSDL.exe tool (not the wsewsdl3.exe tool provided with WSE 3.0 as it contains bugs in it) to create proxy classes. Further the documentation states that WSDL.exe tool will create two proxy classes(if I have installed and configured WSE 3.0 on the development environment). One of the two classes wil contain a suffix wse in its name. I have to use the class that has the suffix wse in its name. The problem I am facing is that WSDL.exe only creates one proxy class. The class with the suffix wse is not generated. Can any one help me with this.

The procedure I am following is as under:

1. My project is WSE3.0 enabled and have created a Security Policy for it as well.

2. The parameters I am passing to WSDL are as under

Wsdl <URL OF WEB SERVICE COMES HERE> /out:c:\ProxyClass.cs /username:<Username comes here> /password:<password comes here>

Kindly reply as soon as possible.

Best Regards

Hammad Haneef Pasha

svcutil.exe and wsdl.exe

johnagrandy — Thu, 10 Dec 2009 01:01:45 GMT

I converted a wsdl file to a C# proxy class using svcutil.exe. Then I converted it using wsdl.exe. The generated proxy classes are similar but different.

Could this be a matter of configuration options ? Are svcutil.exe and wsdl.exe using the same engine under the hood ? What is the history of these tools ?

Any info on how to best generate proxy classes for use in VS08 most appreciated.

Web service upgrade policy

bzinchenko — Tue, 15 Dec 2009 07:26:15 GMT

Hello everybody

I have stumbled on one rather critical point with ASP.NET web service usage having suprisingly little coverage in MSDN and discussion boards. It concerns software upgrade and evolution.

Suppose you have created one very perfect web service, published it and developed client software to access it. You have released software and it circulates widely. Suppose you later decided to extend functionality of your web service by adding new functions to it. Question is, which exact changes you are allowed to make to the service in order not to break its back compatibility with the existing software?

On all search around I have found only this very short reference
http://msdn.microsoft.com/en-us/library/tf3b21x2(VS.80).aspx

It somehow implies that I should update web reference, if i have added new methods to service. But the most concerning issue is just the opposite: what is allowed to do and what is not in order to retain compatibility of the released software, which I cannot control anymore.

Thanks!

The XML page cannot be displayed: Why do I get this error?

JonJacobs — Tue, 15 Dec 2009 14:23:26 GMT

I am running XP Pro. version 5.1.2600 sp2. I use IE 6.0.2900.xpsp_sp2_ etc.

When I type in the URL for my service I get:

The XML page cannot be displayed

Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

A name was started with an invalid character. Error processing resource 'http://localhost/DataFinderHost/DataFinder.svc'. ...

<%@ ServiceHost Language="C#" Debug="true" Service="DataFinder.Service1" %>
-^

Obviously it found the URL. Why doesn't it like the svc file?

Thanks,

Jon

Please Explain this...

gaurawerma — Thu, 10 Dec 2009 10:41:45 GMT

Hi!

Please explain the following paragraph in a simpler way. I just can't get the emphasised part.

"Currently, it is possible to secure SOAP communications over HTTP using the certificate-based Secure Sockets Layer (SSL) protocol. SSL provides encryption and digital signing of both SOAP messages and standard HTTP requests and responses. But SSL has two major limitations that make it unsuitable for securing Web services communications within a service-oriented application. First, SSL is designed for point-to-point communication. However, service-oriented Web services may exchange SOAP messages between two or more endpoints, and so they require a security solution that supports hops across multiple endpoints and multiple domain boundaries. Second, the SSL protocol is built on the HTTP protocol. Web services technology is transport neutral and supports message exchange across different protocols, including TCP and SMTP, in addition to HTTP. The SSL protocol is simply too limiting for Web services technology."

If you can explain this in a simpler way I will be very thankful.

Web service Async method calls in web app

viva-emptiness — Thu, 10 Dec 2009 18:00:10 GMT

Hi,

I am currently working on a client app (web based) using a third party web service. the web service workflow is simple:

Run a search by calling method X and providing some parameters

Run Method Y to check if the search if finished (it is a federated search, so it requires quite some time to gather all the results)

Run the Method Z to retrieve the result set based on the search previously done (specifying the records i want to retrieve as well as the order...)

The web service is by nature async, i am not talking about the "Method1Async" that get's added to SOAP client when you add a reference in visual studio.

I have been working on the sync version of the web service and it is great. now we are moving to the async version.

Any idea in general on how to achieve async operations by running method X and keep checking like every second on the method Y if the search operation is finished before calling Z to retrieve results?

can i use an AJAX update panel or a timer for that? what would be the best approach?

live and code examples are highly appreciated

Thank you

BC30560: 'IPAddress' is ambiguous in the namespace 'System.Net'

WimVM — Mon, 14 Dec 2009 14:07:27 GMT

Hello,

I am building a webservice that has a function in it to add an "A record" in a MS DNS server. When I build the service using svcutil.exe and use the generated vb file in my website. I get the error "BC30560: 'IPAddress' is ambiguous in the namespace 'System.Net'." I notice that the namespace System.Net is included in the generated .vb file by svcutil.exe. When I mark out the full system.net name space in the autogenerated vb file I don't get the error, but then the scripts reports "BC30002: Type 'ARecordInfo' is not defined.". Creating the zone works fine with the same autogenerated vb file.

After about 3 days of troubleshooting I tried a lot of things to get this fixed. I focussed on the ambiguous name space "System.NET". Why does the autogenerated file include this name space? Can it be excluded? Ofcourse without manually marking it out as I do now.

Anyone any idea? Help would be very welcome. Thanks.
