.net - WCF Service Hosted In A Managed Windows Service Connect Using A WCF Service Application
Jul 14, 2011i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
Windows - WCF Hosted As Service?
May 10, 2011I have a VB.NET WCF service hosted as a Window Service. I was able to create an install package, install the service to my machine, and start the service manually from Services in Administrative Tools.Now when I try to reference the service in my test console application (Address: http://localhost:8080/), I get the following error:There was an error downloading 'http://localhost:8080'.` Unable to connect to the remote server No connection could be made because the target machine actively refused it 127.0.0.1:8080`

Consuming WCF Hosted As Windows Service?
Aug 26, 2011I have a WCF Service (with installer) that I have built and installed in Windows Services. Opened up Admin Tools, Services, and started the service without a problem. So now I'm beginning a new project (a simple Windows forms app). I want to consume my new WCF, but have no idea how. I can't seem to add a reference / add a service reference to it.

How To Properly Serve XAP File From Self-hosted WCF Service
Jun 12, 2011I have myself a self-hosted WCF server setup, which serves a clientaccesspolicy.xml and an index.htm which is just points to my xap (accessible via app.xap).
I'm currently serving them via the following code:
Public Function GetPolicy() As System.IO.Stream Implements IClientAccessPolicy.GetPolicy
WebOperationContext.Current.OutgoingResponse.ContentType = "application/xml"
Return New IO.MemoryStream(IO.File.ReadAllBytes("Server Files/ClientAccessPolicy.xml"))
End Function
Public Function GetIndex() As IO.Stream Implements ISilverlightServer.GetIndex
[Code] .....
It works, does the job I'm after. However, I don't think this streams the xap properly, and I know it's a streaming type. If this isn't streaming it properly, how should I stream it? (The endpoint that the XAP and index.htm files are coming through has a webHttpBinding binding). Is it being streamed properly? Or should I make some changes?

View 3 RepliesVS 2010 View Client Transaction Requests And Host Response In A Self Hosted Console Window?
Jan 25, 2012Is it possible to view client transaction requests and host response in a self hosted console window?
Front end client sends request to service
Service console displays requested data in console window and forwards to listening server
Server responds with data
Response is displayed in console window
I guess it would be displaying the traces in the console window.

View 13 Replies.net - Debugging VB Dll Library From Asp.net Hosted In IIS?
Nov 18, 2010I have the following problem. I have some project written in Visual Basic (not Visual Basic .NET but simple Visual Basic - sic!). I can compile it and generate a dll. Then inside my web application I add reference to this dll library. When I run my web application hosted in default Visual Studio server, everything is fine and I can debug my Visual Basic project. However, when I host my web application in IIS then I can't.Code does not stop in my breakpoint. My asp.net catch the exception when I try to execute some method from the mentioned library which is something like:
Unable to cast COM object of type 'xxx' to interface type 'yyy'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{4C2875B5-3265-306B-9C74-1BEC98986B1A}' failed due to the following error: Error loading type library/DLL.

View 2 RepliesClass SELF That Is Hosted By A Couple Different Classes?
Jan 16, 2010I have a class SELF that is hosted by a couple different classes. Basically, the hosting class HOST calls a method in SELF. SELF is passed HOST as an argument in the constructor, so SELF can call methods in HOST. In normal situations, a call to HOST will do something minor, then return so that SELF can continue. However, for one particular type of HOST, one of the calls from SELF to HOST will cause HOST to call SELF, and so on ad infinitum. A classic, though convoluted, case of recursion. Once again, this is only going to happen for one type of HOST. For other types of HOST, that particular call will not cause HOST to call SELF, so there will be no recursion. Nonetheless, there is no getting around it in one case.
I can see two means to decouple the recursion, and I am wondering which one (or a third) would work best:
1) Add a timer into that particular HOST so that the call from SELF that would trigger the recursion would actually just start the timer in HOST, then return. When the timer ticks, HOST can call SELF. The recursion is broken because the call to SELF is done on the timer event, and not when SELF called HOST.
2) As it happens, HOST makes the first call to SELF in a background thread, which means I don't really need to worry whether this thread blocks or not. Therefore, I could have this background thread spawn a second background thread to make the call to SELF, then have the initial HOST thread JOIN on the second thread. This means that the initial thread will block until the second thread finishes. Meanwhile, the second thread will call HOST, and the HOST won't call back to SELF, it will just return like all the other HOST objects would do. This will allow the second thread to run to completion. When the second thread completes, the first thread will take over and call SELF again on a new second thread. Therefore, the recursion is broken because the secondary thread will always run to completion, and the primary thread will wait for the secondary thread to complete, then call it again.
I tend to prefer the second option, because the first option involves a pause of some length (the minimum for a timer, which is pretty small), while the second doesn't, but the first option is actually a little easier to implement.

VS 2010 To Window Service Or Not To Window Service?
Jul 20, 2010I am making a server program, it works, cool.Made it display the info coming in via a textbox, the number of users connected, etc.I based it off of one of the members heres examples (jmcilhinney).However, I am kind of in a rock and a hard place.Do I try and convert it to a windows service so its on all the time? Or do I leave it in a exe format?I have never touched windows services before, but they look promising.However, this will be residing on a collocated server running Windows Server 2003.The problem with that is, if I run it. Person B, C, D, E, whoever.. can not see it due to the virtualized desk tops of RDC (even under the same username).I am kinda curious if I should make it a windows service, then make my 'display' program that just.. remotely taps into it to control it, and view stats and such.The 'server' will take info sent from the client, and add it into a database, then pass back some commands and such.

Debug Windows Service In 2010?
Oct 19, 2011I upgraded to VB2010 from VB2008 early this year and have been working on a Windows Service which I am now debugging. When I was using VB2008 in Windows XP SP3 I would put a Stop statement in the code and when execution got to it a dialog would open asking if I wanted to debug it using a development environment listed in a provided list. The list contained the VB2008 VS IDE which I selected which would in turn transfer me to the IDE in debug mode. I was very happy with this setup.
Now I am using VB2010 with Windows 7 and when the execution reaches the Stop statement the service just stops. It no longer offers the choice and ability to "jump" into the development environment via the dialog that I mentioned.[code]...
VS 2010 Referencing Web Service With Code?
Mar 22, 2011I did a search on the internet but came up with very limited results. I'm using asp/vb and need to create a n application that does the following steps:
1. User defines web service URLs to WSDL pages .. populated in combo drop down (already coded)
2. User selects web service - Clicks Connect
3. User is prompted for any input fields the web service requests.
4. Output (in XML) is displayed after input fields are populated.
I know how to reference web services in the development environment, and use them... but have no idea how to dynamically create them and show the input fields requested.
