I need to remove WcfContrib from a WCF service.
In a nutshell, it is a library to "max out" all the parameters of a WCF channel (timeouts, message size, etc...).
Now, to ensure I don't break the service, I need to be 100% sure that after I remove WcfContrib I keep all the current parameters maximized.
Therefore, I am looking for a way to log/display on a page the "runtime values" of a channel.
I am also open to alternative solutions/suggestions.
Thanks in advance
I've never seen that kind of tool before. But I have an idea about this.
You can develop a WCF endpoint behavior extension for this. This endpoint behavior can get these values that you are interested and log to somewhere.
This way you don't have to change your service code or something. You will just add this endpoint behavior to web.config of your application.

I have a WCF application, that's making an external REST call to gather some data. The call is being made by an included dll, so we have no say in this call; we only have the url. I'm trying to set a timeout in Web.Config file for this (particular) external call. So setting the timeout generically for all the REST calls doesn't work in this case. Can someone point me in the right direction, what should I write in the Web.Config?
you might want to specify a particular WebHttpBinding
So, I'd like to create a behavior that I can apply to my WCF services to return a "dashboard" of sorts. By applying the behavior, I could say goto http://localhost/MyService/MyService.svc/dashboard and get returned a list of statistics for the server that I'm interested in.
I'm not sure where to hook in and override the default service page, there must be an extension point, I'm just not sure where to look. Any thoughts?
EDIT: I've seen ways to do this using HttpGet and Message, but this causes me to modify my existing services. I want a behavior that I can apply across to any service at the configuration level, so that I do not have to modify the services whatsoever.
This seems like a simple question, but I haven't been able to find the answer online via many Google searches. I have a C# web service and, when I visit its ASMX page in the browser, for a particular method it always has the following:
"The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values."
Likewise for SOAP 1.2 and HTTP POST. What I want to know is how I replace the placeholders shown, which are things like:
<myParameter>string</myParameter>
Where 'string' is the placeholder. And in the response:
<xsd:schema>schema</xsd:schema>xml
Where 'schema' and 'xml' are the placeholders. I've been using another web service that has these placeholders filled out with example values for the parameters and responses, and I would like to define such examples for my own web methods, too. I was able to describe the entire method with the following:
[WebMethod(Description="Does awesome things.")]
But I have not found such a thing for the individual parameters of a web method.
By default DefaultWsdlHelpGenerator.aspx is called to generate the "help" page.
You can set another (or modified) template with the wsdlHelpGenerator Element in your web.config file.
Why would you want to do that? That page you see in the browser when hitting your asmx is just giving sample requests and reponses. If you want to get data using those examples, replace the placholder values in the request with what you are querying from the service, and POST to it...
Edit: I mean, if you really need to replace those placholder values, write code in your service to determine when someone does a GET (implying viewing from a browser), and play with the response, changing the placeholder values to whatever you require.
You can't do it. If the help page (which is what you're describing) does not have an input box for a particular parameter, then it means it doesn't know how to do that.
You should not pay too much attention to those pages in any case. They go away with WCF.
They were never of very much use anyway, except for the simplest web services. They were a way to get people into the web service game way back in the beginning when there were no tools to help you test a web service. Use soapUI instead.
BTW, also see Microsoft: ASMX Web Services are a “Legacy Technology” for why it makes good sense to ignore ASMX-only pages.
I'm using .NET 2.0 web services. If I add a reference to a WSDL and make a proxy class method call, what's the easiest way in VS to see the SOAP being sent?
Example, I added the PayPal WSDL Web Service Reference and made a call as so:
PayPalAPIAASoapBinding _client = new PayPalAPIAASoapBinding();
...rest of code and then
SetExpressCheckoutResponseType checkoutResponse = new SetExpressCheckoutResponseType();
checkoutResponse = _client.SetExpressCheckout(request); // makes the call here
I tried setting a debug point on line 2 but not sure how to dive in to see the SOAP. Obviously I could use something like Fiddler but want to just use Intellisense during debugging to drill down to the object that has the request. I would assume client would have it, my instance above but could not find it. Client is an instance of the PayPal Service.
I do see when I drill down into the base class PayPalAPIAASoapBinding that there is a version property but I can't get the value for this:
System.Web.Services.Protocols.SoapProtocolVersion.Default
when I try to paste that into my watch window, the value just shows the word Default not the true value that's sent. So this is why I need to look at the SOAP and so far in that binding object I don't see a property holding it. But it's gotta be somewhere in any requests you make in a web service in .NET, just don't know where to look during debug?
My end goal here is to be able to read the SOAP envelop before it's being sent really using any WSDL reference in VS.
There's no very easy way. See the example in the SoapExtension documentation on MSDN for a way to log the information.
If you were using WCF, you could just turn on logging in the configuration.
The easiest way to see the SOAP messages (regardless of the programming language) is to use a tool like SoapUI or TCPmon which lets you intercept send and received messages.
This is very easy (if the SOAP is not encrypted). Although it is not in VS.
The easiest way is to use the Fiddler. You can let your VS make Soap calls and see the traffic in raw view on the Fiddler. If the Soap calls are made over SSL, there are some extra steps that needs to be taken for Fiddler to trace them.
This seems like it should be really simple, but I'm unable to figure this out.
I am adding a web service reference to my console application. The web service points against our production environment and I would like to test it against development. In VS2005 it was really easy to override the target URI of the service. Is it possible to do the same with VS2008? I would like to set the URI in code or via a config file.
I would really appreciate help with this. Thanks!
If you look in your .config, you should see <endpoint> elements that were added to the <client> section of <system.serviceModel>. Assuming you need to point at only one environment at a time you can simply edit the address attribute of those endpoints to point to whatever URL you want.
If you wanted to change this at runtime you need to use the constructor overload for the client proxy that was created. There should be several overloads that take a parameter called remoteAddress in many forms.
It seems that I was able to get around this issue by going to "Add Service Reference" -> "Advanced" -> "Add Web Reference". This gives me a reference in the form I am most familiar with. Now I was able to override the constructor with the URI parameter. Is that method frowned upon?
