Could not load file or assembly log4net Version=1.2.10.0

Question

when I'm attempting to run my .NET application it's says "Could not load file or assembly 'log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' ".

I'm using CR 2008.

Line 51:         <add assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692FBEA5521E1304"/>

Solution 1

after i install CR Run time my problem was solved..i think the matter was between the 32bit and 64bit version.

here is the link http://downloads.businessobjects.com/akdlm/cr4vs2010/CRforVS_13_0_5.exe

Solution 2

you need to configure it iis Open IIS Go to current server – > Application Pools Select the application pool your 32-bit application will run under Click Advanced setting or Application Pool Default Set Enable 32-bit Applications to True

and thn

Go to %windir%\system32\inetsrv\ Execute the appcmd.exe tool:

I tried (no luck) the version from log4net website, but that one differs from the version included in CrystalReports. The difference is in Public Key Token.
