Answer 1

Most likely it is your WCF service call failed. Check out this blog:

http://sladapter.blogspot.com/2010_10_01_archive.html

Answer 2

i did exactly what mentioned in this link, i mean

1. i change the file "servicereference.clientconfig" to:<endpoint address="../Service1.svc"...>
2. And i activat "WCF Activation" in my server wher i host my webpage.

but still can not see the table of my database.

i tryed to view my "service.svc" in the browser and i get this error:

 

Server Error in '/' Application.

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS.

Source Error:

Line 17: <compilation debug="true" targetFramework="4.0" /> Line 18: Line 19: <roleManager enabled="true"/> Line 20: Line 21: <authentication mode="Forms">

so what you think?

Answer 3

There are actually many places that you have to change from your local server to your host. If do a find on "LCL" you can do a mass update and find them all. The easier/better way is to have two service references, one for your local and for your hosted, then you can just change you "using" statement at the top to switch back and forth

Answer 4

Im still lost

Answer 5

Did you create an Application under IIS or did you just add a Vitural Dirctory?  Make sure you add an Application under IIS.

Hello Sladapter,

i added application under IIS and now i get this error message when i browse my webpage:

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive.

Source Error:

what you think?

 

 

 

Answer 7

Make sure you select ASP.NET v4.0 application pool for this application in the Application Porperty Page.

Answer 8

Hi,

Parser Error Message: Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive.

Please try this:

1. Opeon IIS

2. Select the site

3. Click the basic settings...

4. Click the "Select" button in the Edit Site dialog.

5. Select the ASP.NET v4.0 option from the Application pool drop down list

6. Click "OK" button -> Click "OK" button (or you can click the "Test Settings" button to check if the setting is fine then click "OK" Button)

If above didn't help, one possiblility is that you installed the .net 4.0 before IIS was set up, so you need to reinstall (register) the .Net framework 4.0, please refer to this:

Hope this helps.

Answer 11

make sure you have added system.servicemodel.domainservices.hosting

 after that add this

<system.webServer>

   2:     <modules runAllManagedModulesForAllRequests="true">

   3:         <add name="DomainServiceModule" type="System.ServiceModel.DomainServices.Hosting.DomainServiceHttpModule, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

   4:     </modules>

   5: </system.webServer>

Answer 12

1: <system.web>

Answer 19

Hi,

Thanks to all guys...no works!

i tryed to browe my service.svc and i get this error:

HTTP Error 500.21 - Internal Server Error Handler "svc-Integrated" has a bad module "ManagedPipelineHandler" in its module list.

then i googling that and i find that i should install .net framework v4.0.30319 with:

aspnet_regiis.exe is located in <WINDIR>\Microsoft.NET\Framework\v4.0.30319\

e.g.: c:\Windows\Microsoft.NET\Framework\v4.0.30319\

In a standard command prompt, cd to that folder and run "aspnet_regiis.exe -i" 

Regards to all guys..you are realy gread!
