Hi,
The build in Jenkins in failing due to Nuget Restore failure.
error MSB3073: The command ""D:\NuGet\v3.5.0-rtm\NuGet.exe" restore "..\Demo.sln" -MSBuildVersion 14 -NonInteractive" exited with code 1.
In solution project.json is used with wild cards to get the latest version of nuget package. Also here in project file nuget cache is implemented.
