Nuget Restore via build server "unable to find version"

Question

I have a VS solution and as part of a TeamCity Build, we restore packages from both a private NuGet feed (myget) and the public feed (nuget.org). Most packages restore fine, but it hangs on the ones below for WebApi and Mono.Security. This is all working locally in Visual Studio.

Answer 1

Try using https://www.nuget.org/api/v2instead of https://api.nuget.org/v3/index.json per the nuget docs: https://docs.nuget.org/consume/Command-Line-Reference.

Answer 2

The reason why the build failed, was an old version of nuget.exe. I finally solved this problem by downloading the latest version and put this executable in the Program Files x86 folder. Then I created a new system variabele to point to this executable. After that I add a NuGetInstaller package in my TFS Build Definition to let me configure TFS using this new NuGet.exe. This link helped me to let TFS use this new NuGet version
