Typical block of reference node change looks like:

Before:
<Reference Include="MassTransit, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b8e0e9f2f1e657fa, processorArchitecture=MSIL">
  <HintPath>..\packages\MassTransit.3.0.14\lib\net45\MassTransit.dll</HintPath>
  <Private>True</Private>
</Reference>
After: (file version removed, hint path version number updated)
<Reference Include="MassTransit">
  <HintPath>..\packages\MassTransit.3.0.15\lib\net45\MassTransit.dll</HintPath>
  <Private>True</Private>
