Automatic Initialization Of IIS-hosted WCF Service?
Dec 28, 2010
I have an ASP.NET web-site and a WCF service which is called from ASP. The problem is, that during the first client request the site loads aufully slow, cause some time-consuming static objects are being created inside the WCF service. Is it possible to call any service method (by doing this the wcf object will be created), when the site gets loaded in IIS? (I know there is a solution for this problem in ASP 4 and IIS 7.5, but i'd like to know what's about IIS6-7). It is something like "user emulation") Maybe i can add some event handlers in global.asax?

I have an ASP.Net site using Forms authentication. One of the aspx pages loads a WinForms user control hosted in IE. That control must connect with a WCF service located in the same ASP.Net web site.How can I make the WCF service secure? Currently I have set the WCF service to use AspNetCompatibilityRequirements mode but the user control hosted in IE can't connect to the WCF service as it isn't logged in.

I'm having trouble injecting services dependencies into my WCF service using Autofac 1.4.5. I've read and followed the Autofac wiki page on WcfIntegration but my debugging shows me that my WCF service is created by the System.ServiceModel.Dispatcher.InstanceBehavior.GetInstance() method and not by the AutofacWebServiceHostFactory. What am I doing wrong?
I've set up my ajax.svc file to look like the one in the example for use with WebHttpBinding:
<%@ ServiceHost Language="C#" Debug="true"
Service="Generic.Frontend.Web.Ajax, Generic.Frontend.Web"
Factory="Autofac.Integration.Wcf.AutofacWebServiceHostFactory,
Autofac.Integration.Wcf" %>
My WCF service class Ajax is defined like this:
namespace Generic.Frontend.Web
{
[ServiceContract]
[AspNetCompatibilityRequirements(
RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Ajax
{
public MapWebService MapWebService { get; set;}.....
The service already works fine but I can't get the Autofac bits (read: creation/injection) to work.
Removing the default constructor unfortunately leads to the following exception:
System.InvalidOperationException: The service type provided could not be loaded as a service because it does not have a default (parameter-less) constructor. To fix the problem, add a default constructor to the type, or pass an instance of the type to the host.

I need advice on how to secure my WCF web service hosted in IIS. I am new to WCF and would appreciate any sample code, articles to help me restrict access to my WCF service.
I am in the process of testing and deploying a WCF service that will be available on the internet. I need to secure the web service so that only authorized clients can use the service. I need to be able to detect who the client is making the call to the service. The group I am building this service for wants to use Certificate authentication or IP address to Identify the themselves to call my web service. They do not want to use user name and password.
I have found several articles and code snippets for getting the IP address of the client and Certificate authentication. The problem I found using trying to get the IP address of the client is that since my web service his hosted behind a F5 or some type of reverse proxy I cannot get the true IP of the client. The IP that the web services get is the IP of the F5 or the reverse proxy.
For Certificate Authentication I followed the directions from the 9 simple steps to enable X.509 certificates on WCF located here
http://www.codeproject.com/KB/WCF/9StepsWCF.aspx?msg=3181718. I had a few problems using this setup for my web service. 1) To me it seemed like as long as the user presented a valid Certificate they would be able to call my web service.
2) Does Certificate Authentication work when the security mode is set to Transport? In my production environment only HTTPS traffic is allowed through. I setup a Certificate authention on my service following the steps outlined in the article. I used the SSL certificate assigned to my server for the web services. For the client outside the network the service is hosted on, I used one of the certificates I generated when i tested the code locally. I changed the authentication mode of the certificate to chain trust for both the client and the server. I was able to call the service and recieve a message. I thought that since my certificate was self generated using the makecert command that the web services would not authenticate the client for the service.
how I can secure my services to only allow a few approved clients to call call the service.

I am creating new WCF service and i would like to do two way XML for communicating with third party vendors. My wcf service get the request from the outside program by means of URL and it should response accordingly.
Example - I have url which third party will call and put xml as a request, i have to get that xml, work accordingly and response back with either success or failure and appropriate xml. I need to make it completely automatic so anybody can call that url, it will validate that user and do the next step of request and response.

Can I use the membership provider api on a hosted service? I can create mssql databases but have no control over iis. Will I be able to use the membership admin webpage on the hosted service?
Am I correct in stating that the api uses ASPNETDB.MDF in the app_data folder as it's database?

I have a WCF service that runs in my web application that provides data to a Silverlight application and is defined as follows (with an appropriate .svc file)....
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class DispatchService [code]...
The idea is that the user logs into the website and is then authorised for all services. I do not want to have a login aspect to my Silverlight application to authenticate users.Therefore I dont want anyone to be able to call my service who is not authenticated.
Could I...Somehow determine this for each Operation Contract. I had a look inside the OperationContext object but couldnt find anthing that stood out as a way to determine who the user was.Somehow attribute the ServiceContract so that the method can only be used by authorised users?Put something in my web.config to stop unathorised users from being able to access the folder containing the services?

I am working with this tutorial .[URL] In Visual Studio under the WCF REST program called .. TeamTask.Service is see the folding folders and files
[folder] Properties
[folder] References
[folder] AppData
[folder] Model
[file] Global.asax
[file] TeamService.cs
[file] Web.config
Then I use Build...Publish TeamTask.Service to move this up to my shared hosted server....it builds and publishes successfully
When I reset the client to my virtual directory on my domain...it opens and I get an error that I believe is because it can't find and records or tasks
When i look in the folder that was published to I find this:
[folder] AppData
[folder] bin this has a TeamTask.Service.ddl and TeamTask.Service.pdb
[file] Global.asax
[file] web.config
No folder for Model.

I'm running an ASP page that is using a WCF client to get some data. How can I set/pass the Network Credentials (of the user that performed the request, not the .net pool thread) on the WCF client so the WCF service will be able to perform impersonation using these credentials ?
