Silverlight and WCF

2008-05-12T17:54:00Z

today i had to make silverlight call WCF service so i made a normal wcf service and try to consume it with silverlight and it didn't work ,so i start the debug jury and it lead to no where ,then i serve the forums , blogs ,and documentation but no solution
you can check on silverlight forum.
http://silverlight.net/forums/p/1119/2597.aspx
then i suspected that maybe silverlight client access policy is a must to connect to web service even in debug mode so i added clientaccesspolicy.xml to my wcf service and it works fine now

the code for clientaccesspolicy.xml :
<?xml version="1.0" encoding="utf-8"?>
<access-policy>
<cross-domain-access>
    <policy>
      <allow-from>
        <domain uri="*"/>
      </allow-from>
      <grant-to>
        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>
</cross-domain-access>
</access-policy>

Vista side-by-side configuration Error

2008-03-06T14:19:00Z

just today i had to make a demo for some augmented reality application for a customer
my development machine has windows XP SP2 and my demo machine has Vista
i developed the application using VS 2008 C++ so xcopy should work fine but not with Vista !
i keep getting the error:
" The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more detail "

that doesn't make sense, my application doesn't have any side-by-side configuration
i tried to change the application compatibility and it didn't work
so i googeld the error and found link to the msdn
yes that should be it
but no
so i searched the msdn and found

How to: Deploy using XCopy

that should be it
what i need is to copy
%WindowsSdkDir%\Bootstrapper\Packages\vcredist_x86\vcredist_x86.exe
to the demo machine and it should work

but no the error still the same

i noticed while installing vcredist_x86.exe that it say vs2005 run time !

i found that the new runtime fro vs2008 dose not came with vs2008 instead ms ship vs2008 with the old run time
so i download the new run time from
http://download.microsoft.com/download/1/1/1/1116b75a-9ec3-481a-a3c8-1777b5381140/vcredist_x86.exe
and that is it
it works :)
i don't know who i should blame for this wasted time
