title: Using HttpClient in PCL
body: <p>I'm using Xamarin since 2014 and I always used the Microsoft <a href="https://www.nuget.org/packages/Microsoft.Net.Http/" rel="nofollow noreferrer">HttpClient</a> for the Core project and for the platform specific projects (Android, iOS).</p>
  
  <p>I also developed three utility libs (let's call them <strong>libs</strong>):</p>
  
  <ul>
  <li>Common.Core (profile 78)</li>
  <li>Common.Droid</li>
  <li>Common.IOS</li>
  </ul>
  
  <p>This <strong>libs</strong> contains a lot of utilities and I use them in all my projects (let's call them <strong>EndUserApplication</strong>).
  All of them use the Microsoft HttpClient.</p>
  
  <p>Today I updated all the packages that the <strong>libs</strong> uses.
  The problem is that now the <strong>EndUserApplication</strong> that uses <strong>libs</strong> are not able to install HttpClient from nuget.
  This is the message on the Android applications:</p>
  
  <blockquote>
    <p>Could not install package 'Microsoft.Bcl.Build 1.0.14'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v6.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.</p>
  </blockquote>
  
  <p>The <strong>EndUserApplications</strong> reference also Common.Core and also Common.Droid so, because of Common.Core, I need the Microsoft HttpClient.</p>
  
  <p>Something is definitely changed, infact the description of the Microsoft HttpClient they removed Xamarin.Android e Xamarin.Core:</p>

  <p>What need I to do in order to make my projects work again?
  Thanks a lot!</p>
  
  <p><strong>EDIT</strong>
  Installing Microsoft BCL Build Components directly it works (version 1.0.21) and it let me install Microsoft HttpClient.
  If I install the client direcly, I get the error. I noticed that in this way it try to install the version 1.0.14 </p>
  
  <p>I updated Xamarin today, but nothing changed</p>
