WCF Deployment Issue

Recently I got a chance to deploy a WCF Service application on IIS 7.0. Deployment is more or less similar as a normal ASP.Net deployment, so I followed the same procedure. But when I tried to run service.svc file in the web browser it threw an error

HTTP Error 404.3 - Not Found

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

This is the thing you need to care about; handler is missing in this case. So you need to add the handlers for the svc content type. Here is the process for that:

Applicable for IIS 7.0:

  1. Open IIS Manager MMC snap-in.
  2. In the left pane, expand the node with the computer's name, then expand the Web Sites node, and then select the Default Web Site.
  3. Double-click Handler mappings in the Features View.
  4. In the list of application mappings, verify that the .svc file is mapped to the aspnet_isapi.dll. If the file has not been mapped:
    1. Click Add Managed Handler.
    2. Type *.svc into the Request path:.
    3. Type System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 into the Type textbox.
    4. Type svc-Integrated into the Name: textbox.
    5. Click OK.
    6. Click Add Script Map.
    7. Type *.svc into the Request path:.
    8. Type %SystemRoot%\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll into the Executable: text box.
    9. Type svc-ISAPI-2.0 into the Name: text box.
    10. Using the Move Up/Move Down controls, ensure that the managed handler (svc-Integrated) appears before the aspnet_isapi (svc-ISAPI-2.0) handler in the list.
    11. Click OK.

After that I browse my svc file again and it was working perfectly fine.

Much has been said and much has been written about the PTI’s Peace convention on 25 th December 2011. I didn’t get a chance to physically go there and become the part of the history, because history was in the making. With no suspicions that gathering was one of the biggest in the history of Pakistan. I have got several reasons to stamp this event in my memories and I would surely like to tell my next generation about that as well. I personally like Imran Khan right from my childhood days. When I grew up, like any other Pakistani boy I started to love Cricket. My interest in cricket developed from the famous sixer hit by Javed Miandad and it didn’t seek for respite after that. The 1987 Pak-England series and World Cup 1987 further ignited the fire. I saw Pakistan Cricket in serious business. I on no account found that team losing hope till the last ball of the match. Win or lose didn’t matter to me a lot that time, only thing that mattered to me was the way my team fought. Soon I re...

Dynamics 365 - Creating a view on runtime and assign it to the subgrid lookup field

Recently during one of the tasks I was doing, I came up with a problem where I had to filter a lookup on a subgrid (for example Entity2) based on a value in another lookup (for example Entity1) on a Case form. If I had to filter the lookup on a subgrid for Entity2 for Case then that feature is available out of the box. For understand the example see following screen shot: The lookup highlighted above needs to be filtered based on the value in the lookup of Entity1. Here in this example Entity1 and Entity2 are related to each other with N-N relationships. Following javascript code can be used to achieve this task. You need to call this function on form's OnLoad event. function  filterLookup() {      var  subgridAddButtonId = "Entity2_addImageButton";          //Try to get the element from both the current and the parent document.      var  subgr...
