Assembly Load Trace: The following information can be helpful to determine why the assembly 'Coversant.Win32' 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].

I use the following steps to publish the application on local IIS

1. Create an AppPool with Admin credentials in IIS Manager.
2. Change the .Net Framework version of AppPool to 4.0 in AppPool's basic settings.
3. Create a Asp.Net WebSite in IIS manages and associate the AppPool with it.
4. Associate a directory for applications physical directory the and set credential for access/ otherwise grant sharing permissions to the directory (verify by "Test Settings").
5. Now i have created a publish profile to publish the application ..... and it crashes by giving the above error.

Now after searching  i found someone ask to modify reg setting, some say to modify pipeline. but such solution do not work on production as MS do not recommend to use such solution. so now i found the simplest solution.

Just Go To IIS Manager > AppPool > Advanced Settings  Now "Enable 32-bit Application " as shown.And thats it all works fine after IISRESET.
