I\'m following this easy tutorial to start coding with the Google+ API in C#. However, I\'ve been stuck for hours on Step 3, where the first substeps are:
I had this problem and found a fix that may or may not work for you. I had to edit the csproj files because they were pointing to wrong or non-existent packages folders.
Look for the reference paths in your csproj file and be sure the packages folder path is correct:
..\packages\path\to\file.dll
Maybe because of an unusual folder setup, that needs to be ..\..\packages. Also, towards the top, NuGet adds this line:
..\
If you had to edit your HintPaths, you probably also need to edit this. In my example you'd change the value to ..\..\. Finally, at the bottom, NuGet adds a target with the name EnsureNuGetPackageBuildImports. You'll see a couple of attributes with the ..\packages paths in them. Again using my example, you'd have to change this to ..\..\packages. The base for all of these values is of course the folder containing the csproj file.
It may be unusual for your folder paths to be set up in a non-default manner, but mine were, and this information would have been useful to me.
