title: Unable to build project with Google APIs (.Net)
body: <p>I'm unable to build a project that uses the Google APIs.  I followed the build instructions at <a href="https://code.google.com/p/google-api-dotnet-client/wiki/Build" rel="nofollow">https://code.google.com/p/google-api-dotnet-client/wiki/Build</a>.  I get several errors like the following:</p>
  
  <pre><code>Warning 5   The primary reference "Google.Apis" could not be resolved because
  it has an indirect dependency on the framework assembly "System.Net.Http, Version=1.5.0.0,
  Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the
  currently targeted framework. ".NETFramework,Version=v4.0". To resolve this problem, either remove the reference "Google.Apis" or retarget your application to a framework 
  version which contains "System.Net.Http, Version=1.5.0.0, Culture=neutral, 
  PublicKeyToken=b03f5f7f11d50a3a".   
  </code></pre>
  
  <p>I also tried using NuGet to resolve dependencies, but I get:</p>
  
  <pre><code>Install failed. Rolling back...
  Install-Package : Could not install package 'Zlib.Portable 1.9.2'. You are trying to install this package into a project that targe
  ts '.NETFramework,Version=v4.0', but the package does not contain any assembly references that are compatible with that framework. 
  For more information, contact the package author.

  <p>The documentation says the the 4.0 Full Profile is supported.  What am I doing wrong?</p>
