Test Your webservice/WCF service in Network

Today i found a interesting solution for an interesting problem.

i have created a WCF service in .NET Framework 3.5 to be used by PHP developers.
We have decided to test the service before going forward, for that we have planned to launch it on web servers but, i found there was 2.0 framework installed on my web server and my service is built on framework 3.5 (it was not good time to play with web server). So i decided to expose my WCF service from my system only. To do so i setup it on my local server on port 70. but it was not available from other computers on network. So i got a trick to solved this problem.

Solution:
- I downloaded Microsoft SOAP Toolkit version 3 and started MSSoapT (Trace Utility),
then i created a formatted trace listening on port 8080
to do so, i gone throw these steps:
-- File->New->Formatted Trace. it opened a dialog box and i filled the following values in it.
-- Local port= 8080
-- in forward to section, Destination Host= 127.0.0.1 (remove text localhost)
-- port = 70 (my WCF service port number).

Now click ok and its DONE... :)
now every one from my LAN can use this service by url like http://MySystemIP:8080/myservicename.svc

So what we have done is we have used port forwarding technique to expose our WCF services in network. so when user will access port 8080, the request will be forwarded to my service's port 70.

Setup WCF services on IIS

To setup WCF services on IIS, Please follow below steps:

- If you have not registered script map then register it
- open command prompt with administrative rights.

- now go to sites->default web site.
- Right click on "default web site", click on "add application" and fill required details.
- now right click on your application under "default web site" and click on "edit permission".
- in "edit permission" dialog box go to "security" tab and check that there must exists a user "\IIS_IUSER" with read permission.
- if IIS_USER not exists there then click on "add" and add "\IIS_IUSER" and provide it read permission.

What is Endpoints in WCF service

Every service must have Address that defines where the service resides, Contract that defines what the service does and a Binding that defines how to communicate with the service. In WCF the relationship between Address, Contract and Binding is called Endpoint.

The Endpoint is the fusion of Address, Contract and Binding.
in simple language using Endpoint the client application can communicate with your WCF service.

What is procedure to host WCF webservices

WCF is a flagship product from Microsoft for developing distributed application using SOA. Prior to WCF traditional ASMX Web services were hosted only on Internet Information Services (IIS). The hosting options for WCF services are significantly enhanced from Microsoft .NET Framework 3.0 onwards. In WCF there are three main parts: Service, Endpoints and Hosting Environment. Multiple services can be hosted using a single host process and also the same service type can be hosted in multiple host processes. We can host a WCF service in two ways - Self Hosting and IIS Hosting. Here we will examine Self Hosting along with a comparative discussion of different hosting environments.

elf Hosting Vs IIS Hosting

Let’s look at  the differences between the two hosting types
available for a WCF service.

Self-Hosting	IIS Hosting
Needs to add code to host the process	Automatic hosting
Host process should be running before client makes a call to the service.	IIS host runs automatically when a client makes a call to the service.
Automatic process recycling not possible	Automatic process recycling not possible
Can   controlled the service lifetime using Open and Close methods	Lifetime cannot be controlled manually.
Easy to deploy	More difficult deployment than  Self-Hosting

 

Protocols Supported

IIS6	http, wshttp
IIS7	HTTP,net.tcp,net.pipe,net.msmq
Windows console and form application	HTTP,net.tcp,net.pipe,net.msmq
Windows service	HTTP,net.tcp,net.pipe,net.msmq
WAS	HTTP,net.tcp,net.pipe,net.msmq

Steps to host WCF services

This is the Procedure to host and publish your Website : 1-Change the EndPoints in ServiceReferences.ClientConfig and any where there are Endpoints to
2-Right Click Project.Web and then select (Publish) :
a-Publish method :FTP
b-Target Location :any Folder(X)

3-When you have Images and ect.. you should all put in ClientBin in your (X) Folder

4-Configure your IIS >> Add the MIME types Like this >>>

5-Add your Publish Folder to C:\Inetpub\wwwroot

6 >>

1. Open IIS
2. Expand Sites
3. Right click on Default Web Page and select "Add New Virtual Directory" option
4. In the opened pop-up window input "Alias" as Test and populate "Physical path" with C:\Inetpub\wwwroot\TestApp and click "OK"
5. Right click on the created virtual directory (Test) and select "Convert To Application" option from the content menu.
6. In the opened pop-up window make sure you have selected by clicking the "Select..." button Classic .NET AppPool in "Application pool". Click "OK".


7-Copy the clientAccessPolicy.xml and crossDomain.xml to your C:\Inetpub\wwwroot folder.

a-clientAccessPolicy.xml:















b-crossDomain.xml :








8-In your Sql Server , Give IIS Users Permissions to Access your Database.
