C# - System.ServiceModel.CommunicationException On Overloading Webservice?
Jun 15, 2010
I am load testing my webservice
and get a
System.ServiceModel.CommunicationException
when I use 10 threads to communicate to it (without any sleep in between) - basically testing 10 conenctions at a time - through a windows application
An error occurred while receiving the HTTP response to http://localhost/XXX/XXXService.asmx. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.Why would this happen and how to best resolve it Also is this the way how asp.net application will interact with it too - is threading the best way to do the load testing

Here is how my 2 projects are
I have a class library project which consumes multiple webservices. I have created a test project in VSTS and try to call one of those service
But I'm receiving System.ServiceModel.EndpointNotFoundException. In my Test Project I have added one app.config file and added endpoint as available in my Serviceclass library project app.config.

}
IAsyncResult BeginDoWork(object sender, EventArgs e, AsyncCallback acb, object extraData)
{
nor = new ServiceReference1.Service2Client();

//return nor.BeginProductList(acb, extraData);
}

I've a solution which consists of a web project and a class library project. The web project solution directly references a wcf service. There is a 2nd wcf service, but it is the class library project which directly references it. I'm adding the class library (output) as reference to my web project.
Hence in my web project's web.config I now have two scf services configured. This process was easy since I had manually copied the app.config (system.serviceModel part) directly to the web.config, and then configured the web project to talk directly with another wcf service (directly, not through any dlls).
My web project needs to talk to a 3rd web service (asmx). Again I plan to bring this as a class library and include the dll into my web project. (This is a separate solution). When I took a look at this particular class lib project's app.config, I thought i just copy those necessary sections and merge it correspondingly with my current web.config.
So for the 3rd class lib project (which references the asmx service) I happened to notice that it had, under the bindings node, a node called basicHttpBinding, and next, a customBinding. Then further under the client node, there were two endpoint nodes which had the service attributes. (I don't understand why there should be two end points here first of all).
So I copied what came under the bindings node (from the 3rd class lib prj app.config) and appended it to the bindings node (in the web.config). I did a similar process for copying the end points too. But now when I try run the web site I get an exception which halts at the time of initializing the soap client (asmx service): it says something like its not able to determine the endpoint for this contract.
The web.config before I add the asmx web service looks like this:

I've run into a problem with WCF REST Service. I get:
Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
when running inside of the IIS in an ASP.NET 4.0 AppPool.
The problem seems to occur only if:Running inside of IIS
When ASP.NET Comaptibility is enabled
Running in Cassini - no problem it works properly. Running with ASP.NET compatibility off - no problem it works.
It appears that it's some sort of handler version conflict trying to instantiate the wrong version of the handler that in turn tries to load an older version of System.ServiceModel, but I haven't been able to trace this down.
Anybody seen anything like this before and have any ideas how to track this down further?
I've looked in ApplicationHost.config and the master web.config files for System.ServiceModel and HttpHandler references but no luck.

I have a base class with the the following enum and property:
Public Enum InitType
Focus = 0
Help = 1
ErrorToolTip = 2
End Enum
[Code]....
First off, how do I do this - is it by simply overloading it? And secondly will my original property pick up the new enum automatically when using the derived class or will I need to overload that too?

In Visual Studio 2008 I have a Class Library project (called Media) to which I added a Web Reference (not a Service Reference) to a third-party web service (wsdl). In the Class Library project a proxy class is created for using the service along with several classes for the types used in that service.
I also have a second Class Library (called Sync) that references the first one. And then I have a Web Site project that references the second class library. All of this is .NET 3.5
So Web Site > Class Library (Sync) > Class Library with web service reference (Media)
I want to step into the generated code, so I fire up the web site in IIS 7.5 and trigger the call to a method in the second class library (Sync) that in turn should call the web service proxy. I was fully expecting to hit the breakpoint, but instead got an exception:
Unable to generate a temporary class(result=1). error CS0029: Cannotimplicitly convert type Media.WebService.multiValuedAttribute to Media.WebService.multiValuedAttribute[]
Why is ASP.NET trying to generate a temporary class? Don't I already have the generated class from the first Class Library (Media)?
