I'm unable to build a project that uses the Google APIs. I followed the build instructions at https://code.google.com/p/google-api-dotnet-client/wiki/Build. I get several errors like the following:

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".

I also tried using NuGet to resolve dependencies, but I get:

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.

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

  • Let me know what solution works for you, because there are several users who complain about a similar problem. Thanks! – peleyal Jul 23 '13 at 21:14
  • @peleyal As I look back at it, I think it failed because I had a file in my project called service.vb. – Edwin Oct 25 '13 at 01:02

I've got it working now. I'm not exactly sure what fixed it.

I had an old version of NuGet installed in VS 2010. I might have originally installed it as an administrator, because I had to open VS2010 as an administrator to remove it. After removing NuGet, I installed the latest version. I was then able to do package-install google.apis -pre and package-install google.apis.authentication -pre with success. But my project still wouldn't compile. From my memory, though I could be wrong, the only other thing that I did was remove the Google API Lib references from a separate project in the same solution, and then the compile errors were gone.
