ASP.Net MVC application is saying build failed but doesn't show me any error but warns "Found conflicts between different versions of the same dependent assembly"

Hi,

I have received an ASP.Net MVC application from a colleague that I have to start working on, it had different dll reference errors when it was given, at that time it was showing me errors in the errors list, after adding the dlls when I compiled the Orange sign on the dlls is gone but when I compile the application it says build failed as below:

Rebuild All: 3 succeeded, 1 failed, 0 skipped

But its not giving me any details about the error in the error window. I could able to build all other assemblies individually by unloading the UI application, then added UI application still it gives me failed and doesn't display the details of the error in the error Window.

Here are the Warnings I am getting, any help would be very helpful - thanks in advance friends.

Warning 3   Found conflicts between different versions of the same dependent assembly. In Visual Studio, double-click this warning (or select it and press Enter) to fix the conflicts; otherwise, add the following binding redirects to the "runtime" node in the application configuration file: <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"><dependentAssembly><assemblyIdentity name="log4net" culture="neutral" publicKeyToken="669e0ddf0bb1aa2a" /><bindingRedirect oldVersion="0.0.0.0-2.0.8.0" newVersion="2.0.8.0" /></dependentAssembly></assemblyBinding> XXXXX.SUD.CRS.Services (XXXXX.SUD.CRS.Services\XXXXX.SUD.CRS.Services)

Thanks,

Abdul Aleem
