title: NuGet installing package error
body: <p>i am currently trying to create a NuGet package for zLib (<a href="http://www.zlib.net/" rel="nofollow noreferrer">http://www.zlib.net/</a>).
  I used the "grpc zlib" NuGet package (<a href="https://www.nuget.org/packages/grpc.dependencies.zlib/" rel="nofollow noreferrer">https://www.nuget.org/packages/grpc.dependencies.zlib/</a>) to copy the folder structure and then added the zLib .dll, .lib and header files. </p>
  
  <p>This is my self crafted zlib NuGet-package: <a href="https://drive.google.com/file/d/0B_2A8x02vzDwOWVGUmxkeGdBNm8/view?usp=sharing" rel="nofollow noreferrer">https://drive.google.com/file/d/0B_2A8x02vzDwOWVGUmxkeGdBNm8/view?usp=sharing</a></p>
  
  <p>However when i try to install my package in VS, then i get following error:</p>
  
  <blockquote>
    <p>Severity  Code    Description Project File    Line    Suppression State
    Error     Could not install package 'zlib 1.2.8'. You are trying to
    install this package into a project that targets
    'native,Version=v0.0', 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.         0</p>

  <p>Using the grpc zlib package is working fine.</p>
  
  <p>Thanks for your help in advance!</p>
