Solution 1

It seems that one of the projects in your solution or maybe some 3rd party dll has been built with different version of log4net. Either you update references to log4net in all projects or you could add assembly redirection setting to the web.config
Put below tags in Web.config, anywhere under configuration element.

HTML

<runtime>
    <assemblybinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentassembly>
            <assemblyidentity name="log4net">
                          publicKeyToken="1b44e1d426115821"
                          culture="neutral" />
            <bindingredirect oldversion="1.2.10.0">
                         newVersion="1.2.13.0"/>
        </bindingredirect></assemblyidentity></dependentassembly>
    </assemblybinding>
</runtime>

Are you using IIS 7 version

Madhav Gunjal 2-Jan-16 5:02am

no its 8.5,and OS is windows8

koolprasad2003 2-Jan-16 5:05am

OK. Then I think you have not enabled 32Bit application in your application pool.
do the following steps
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
Restart IIS and try again

If this option is not available to you, follow these next steps:
Go to %windir%\system32\inetsrv\
Execute the appcmd.exe tool:

I got the solution for above problem.i simply copied log4net.dll assembly file from my development machine and copied the that dll assembly file to the bin folder of my project,on that machine on which I am deploying the application
and I think whatever problem will arise regarding assembly missing or not loading kind off ,we can resolved by following the same steps

this above comment posted for those who are facing same problem that's it,now I have another problem n that is, after resolving all errors regarding crystal report the lastly report should be render but its not showing any thng like a report it shows ,
Error
Cannot find a control with ID 'CrystalReportSource1', referenced by CrystalReportViewer1.ReportSourceID.

check if crystal report viewer DLLs are present in your GAC (C:\windows\assembly), check with Crystal Runtime Version there is something conflict

Madhav Gunjal 3-Jan-16 23:47pm

actually I am deploying my asp.net application on another machine where vs and sql server is not install but I have placed all required dll file in bin folder in which crystal report related dll's also present and the version of crystal report runtime is Version=13.0.2000.0

okkk sir, and I need ur one more help regarding another error
and that is

Retrieving the COM class factory for component with CLSID {4DB2E2BB-78E6-4AEA-BEFB-FDAAB610FD1B} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

Thank you sir in advance

koolprasad2003 4-Jan-16 0:07am

Which COM object you are using ? Word or excel or what ? basically error code 80040154 suggest the said GUID is not found in registry or has no access
