Could not load file or assembly 'App_Web_rdtli7if' - Typical type of error ( No google )

I am using Silverlight 2 ( Studio 2008 ). I have created WCF Service and my silverlight is using this WCF service.

It was working fine till a hour ago. But, All of sudden I am getting following error. Anyone has any idea about this.

 Could not load file or assembly 'App_Web_rdtli7if, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IO.FileNotFoundException: Could not load file or assembly 'App_Web_rdtli7if, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'App_Web_rdtli7if, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' could not be loaded.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

hey ankitavyas

I experienced the same issue.

To resolve it, i removed the generated XAP file from the associated web solution delivering the silverlight application.

It appears that the WCF references fell out of sync between silverlight app and hosting web-app.

Make sure that the FUSION LOGGER is enabled (see registry setting below). This gave me some additional pointers as to the assembly binding failures

HLM/Software/Microsoft/Fusion!EnableLog = 1 [type = DWORD].

NOTE : There is a VS.NET performance hit setting this.....

Hope this helps...

Cheers

RATS....still getting the error....this makes no sense.....seems VS.NET is not cleaning up after itself.

hmmm, I could not get to the bottom of the issue ?.

To solve it, I recreated my WCF service as a standard web-service (ASMX)....I don't get that error anymore

Hi,

Had the same problem... (SilverLight 2, WCF Service)
Found this temporary fix...

1. Close Visual Studio 2008
2. Go to C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
3. Delete the current working project directory/files

Also had the same problem, tried several fixes, the only thing that worked was deleting the project temp file.

Thanks, John

This is a Caching issue. What you should do is stop website from iis. close the Application pool from iis then Clear ASP.NET cache by deleting all the files in  C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files. This will Solve your problem for sure
