title: VSTS/Azure DevOps: Auto-Increment NuGet Package Version on Pack
body: <p>Running the .NET Core Pack task, how do I get the outputted NuGet package version to auto-increment itself? </p>
  
  <p>So, for example, if my current version is <code>1.0.0</code>, then the next time I call the Pack task, I would like to see <code>1.0.1</code>.</p>
  
  <p>I'm using environment build variables with <code>Build.BuildNumber</code> and getting outputs at the moment of e.g. <code>20180913-.2.0</code>, etc. I would like to establish to a more traditional versioning system.</p>
