title: How to resolve the c# build warning Found conflicts between different versions of the same dependent assembly
body: <p>There are multiple warnings for multiple versions of same assembly are getting download at the time of build like mentioned below. Also one more point, most of these assemblies are getting downloaded because of dependencies in the Nuget.</p>
  
  <p>C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets (1605): Found conflicts between different versions of the same dependent assembly.</p>
  
  <p>2>  There was a conflict between "Ionic.Zip, Version=1.9.1.5, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c" and "Ionic.Zip, Version=1.9.1.8, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c".
  2>      "Ionic.Zip, Version=1.9.1.5, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c" was chosen because it was primary and "Ionic.Zip, Version=1.9.1.8, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c" was not.
  2>      References which depend on "Ionic.Zip, Version=1.9.1.5, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c" [C:\TFS\DSCNC\Dev\CatalogServices\Background\packages\DotNetZip.1.9\lib\Ionic.Zip.dll].</p>
  
  <p>One of the way to resolve this issue would be to check in the latest assembly in Packages folder.</p>
  
  <p>Is there any way or configuration setting that we can prevent downloading of multiple versions of same assembly?</p>
